Description
Technical Field
The present disclosure relates to an electronic device, and more particularly to a batteryless active and passive hybrid device for secure wireless payment comprising a secure element.
Background
EMV was named after its originator in 1994 (Europay, MasterCard and Visa), which now defines a set of credit and debit card transaction security standards that can be used for NFC mobile and contactless payments. An "EMV card" or "EMV credit card" uses a smart chip instead of a magnetic stripe to hold the data needed to process a transaction. EMV brings enhanced security and global interoperability for credit cards and mobile payments. The chip on the EMV card may have much more advanced authentication capabilities than a magnetic stripe credit card. Essentially, each EMV card has embedded therein a fully functioning computer system. The chip is tamper-resistant, making it almost impossible to clone.
Since EMV is almost one hundred percent effective in preventing face-to-face (in-store) false card fraud, the click-to-press convenience of contactless EMV cards is likely to increase credit card loyalty and consumption. Therefore, it is desirable to incorporate EMV cards or the like into various mobile wearable devices for contactless or mobile payment operations.
With mobile EMV, the account credentials of the customer are loaded directly onto an NFC enabled cell phone or wearable device, which is as secure as contactless EMV but has higher convenience and more opportunities for utilization, in particular, existing contactless payment systems are smart mobile devices, such as smartphones, smartwatches, etc., that utilize EMV credit or equivalent cards (e.g., union pay cards) and use wireless communication modules (e.g., NFC) for secure payment.
The embedded chip and antenna of the contactless payment system enable users to conduct lower value transactions by waving their smart phone or smart watch over the reader of the point of sale terminal. Since you no longer need to count money or take out a heavy wallet for cash payment, the embarrassing moment when long teams stare at you count money no longer occurs. Global fast food chains and convenience stores have used POS terminals to conduct contactless payment transactions.
Smart mobile devices, such as smart watches, employed by contactless payment systems often include contactless active payment units or modules that need to be powered by their built-in powerful batteries. However, for a variety of reasons, many do not want to use any smart watch and prefer to use a traditional watch.

Referring to fig. 1, a block diagram of a hybrid batteryless active and passive device according to a preferred embodiment of the present disclosure is shown, according to which the hybrid device for secure wireless payment comprises a secure element 20 adapted to store at least one secure payment applet and at least one token for secure contactless payment and to be operatively connected with an active operating unit 10 and a passive operating unit 30.
The hybrid device is configured to be switchable between an active state and a passive state in response to operational requirements and conditions of the various operations required. In the active state, the active operating unit 10 is activated on demand, preferably wirelessly, for example by means of an external power supply or an initiator/activator, to enable the hybrid device to act as an active device and to be suitable for various operations requiring a high and stable power consumption, in particular for providing the secure element with personalization information of a payment card and/or a payment token of a device. In this regard, the active operating unit enables the hybrid device to support end-users for installation and loading of third party applications.
In the passive state, the active operating unit is deactivated and/or separated from the external activator and the passive operating unit is activated to enable the hybrid device to function as a passive device and to be suitable for various operations requiring relatively low or instantaneous power consumption/power, in particular for payment token authentication and/or contactless payment transaction operations by means of said secure element, wherein the low or instantaneous operating power can be obtained from a predetermined matching device adapted to work with the passive device.
In some embodiments, such as the one shown in fig. 1, when in the active state, the active operating unit 10 is activated by being operatively coupled with and powered by a wireless power transfer unit 60 for wireless data communication with a configuration unit, such as a dedicated machine, a computer with a dedicated module for configuring data to the secure element 20, a smart or mobile device, for configuring personalization information of the payment card and/or payment tokens of the device according to/from the configuration unit to the secure element.

In some embodiments, the active operation unit comprises a first wireless communication unit adapted to couple with and wirelessly communicate data with the personalization information and payment token configuration unit. The first wireless communication unit is operatively coupled to a wireless power receiving unit and/or a transient power storage unit, preferably an ultracapacitor, adapted to receive and/or store power from the coupled wireless power transfer unit in order to be able to perform routine and specific operations of the hybrid device requiring high and stable operating power.
In some embodiments, the first wireless communication unit is a WIFI, BLE and/or NFC enabled communication unit.
In some embodiments, the passive operating unit comprises a second wireless communication unit adapted to couple and conduct wireless data communications with the payment transaction unit and operatively coupled with the antenna unit to receive its operating power and payment transaction data and signals from the coupled payment transaction unit.
In some embodiments, the second wireless communication unit is an NFC enabled communication unit acting as an NFC passive target unit configured to draw its operating power from a payment transaction unit acting as an NFC initiator unit.
In other embodiments, the first wireless communication unit and the second wireless communication unit are both or the same NFC enabled communication unit, i.e. the first wireless communication unit and the configuration unit are both active mode NFC communication units, since the NFC device can operate in a peer-to-peer mode, which allows two active mode NFC enabled devices to communicate with each other for exchanging information in an ad hoc manner, wherein one device will deactivate its RF field while it is waiting for data.
In some embodiments, the antenna element comprises an antenna having dimensions of 10 x 24 mm. This size is quite desirable for stable and reliable data communication with the payment transaction unit without the need to incorporate an antenna booster to ensure proper operation of the passive operating unit as may be found in some prior art devices using smaller or miniature antennas. If the size of the antenna is large, the hybrid device cannot be integrated into some conventional wearable devices, such as conventional watches and jewelry.
In some embodiments, the security element, the active operating unit and the passive operating unit are configured to be operatively coupled to each other and mounted on a bendable board/flexible board that is adapted to be easily mounted on a non-planar or curved surface or easily inserted or embedded into a curved receiving space.
Referring now to fig. 2, there is shown a block diagram of a hybrid batteryless active and passive device according to another preferred embodiment of the present disclosure, according to which the hybrid device for secure wireless payment comprises a secure element 200 adapted to store at least a secure payment applet and at least a token for secure contactless payment and to be operatively connected with an active operating unit supporting Qi and BLE and a passive operating unit supporting NFC.
In some embodiments, such as the embodiment shown in figure 2, the active operating unit is a Qi-enabled BLE unit 100 comprising a Qi standard power receiver, and the wireless power transfer unit is a Qi-enabled power transfer unit 600 comprising a Qi standard power transmitter for wirelessly powering the BLE unit for wireless data communication with the configuration unit, i.e. with the smartphone 400 as shown in figure 2. The passive operating unit is an NFC passive target unit 300 operatively coupled with and wirelessly powered by a payment transaction unit, i.e. with the POS terminal 500, and configured to draw its operating power from the payment transaction unit as NFC initiator unit for payment token verification and/or contactless payment transaction operations with said payment transaction unit through said secure element 200.
Furthermore, in the hybrid device as shown in figure 2, the security element 200, the Qi-enabled BLE unit 100 and the NFC passive target unit 300 are operatively coupled to each other and mounted on a bendable plate/flex-plate 700, which is adapted to be easily mounted on a non-planar or curved surface or to be easily inserted or embedded into a curved accommodation space.
In some embodiments, the hybrid device is mounted on and preferably embedded on or within the wristband or wristband clip of a conventional watch in order to replace the original wristband or wristband clip of the user's watch for contactless payment transactions and other applicable operations so that the user can wear and use the watch in a conventional manner while benefiting from the contactless payment functionality provided by the new and replaceable portion of the watch.
A conventional wristwatch mainly includes a mechanical part and a metal material for a case connected with a band or a wrist band. The wristband may also be made of a variety of materials, including leather, plastic, metal, and the like. Under normal circumstances, adding smart functionality (such as a payment applet) on this part of the wearable device requires the use of a battery in order to be able to communicate with an external device (such as a smartphone).
Challenges or problems with adding integrated battery power to traditional wearable products are as follows:
design and aesthetic problems, where the battery is rigid and its placement takes up space, adding unnecessary thickness, affecting aesthetics and design;
the problem of battery recharging, in which the continuous use of rechargeable batteries requires the addition of components and interfaces, such as cable accessories for connecting the devices, affecting the aesthetics and the production costs of the final product;
battery replacement problems, in which the life of all the batteries is limited, which require replacement, whether or not the batteries are rechargeable; and
waterproof issues, where the encapsulation of the battery and charging cable interface would limit the waterproof capability of the entire device.
The technical solution proposed by the present invention thus clearly allows to solve the above mentioned technical problems, which allow to power traditional and basic wearable products (including but not limited to watches and jewelry) as required, while eliminating the dependency and need for integrated batteries. The present disclosure incorporates a flex-board that can implement a unique/unique payment token configuration procedure to add NFC payment capability on traditional and basic wearable products without the need for an integrated battery power source. Being able to make the battery detachable from the wearable device while having the ability to communicate with the smart device through bluetooth technology is critical to overcoming all of the above challenges or problems in the prior art.
Referring to fig. 3, there is shown a flow chart of a method for providing contactless payment capabilities to a conventional wearable device by a batteryless hybrid active and passive device for secure wireless payment, the hybrid device comprising a secure element adapted to store at least a secure payment applet and at least a token for secure contactless payment and being operatively connected with an active operating unit and a passive operating unit, the active operating unit preferably being adapted to be removably connected with the secure element, the method comprising the steps of:
mounting/embedding a batteryless hybrid active and passive device on/within the legacy wearable device (801);
switching/setting the hybrid device to an active state to cause the secure element to configure personalization information of a payment card and/or a payment token of a device (802); and
switching/setting the hybrid device to a passive state such that the secure element is configured for performing payment token validation and/or contactless payment transaction operations (803).
In some embodiments, the aforementioned method comprises the steps of:
mounting/embedding a batteryless hybrid active and passive device on/within the legacy wearable device;
switching/setting the hybrid device to an active state by having the active operating unit wirelessly activated as required or activated by an engageable and disengageable or detachably/detachably connected external power transfer unit to enable the hybrid device to act as an active device and the secure element to configure personalization information of a payment card and/or a payment token of a device; and
by deactivating the active operating unit wirelessly, or by detaching/decoupling from the external power transfer unit, as required, and activating/configuring the passive operating unit to switch/set the hybrid device into a passive state, to enable the hybrid device to act as a passive device and to configure the secure element for performing payment token authentication and/or contactless payment transaction operations.
According to another aspect of the present disclosure, there is provided a configuration process flow for a batteryless active and passive hybrid device for secure wireless payment, the hybrid device comprising a secure element adapted to store at least one secure payment applet and at least one token for secure contactless payment, the configuration process flow being as follows:
step 1: a token strap or hybrid device with a security element is placed on top of the activated or charged token mooring to wirelessly receive power from the token mooring to power its BLE unit.
Step 2: a mobile application is launched on the smartphone and standard BLE pairing with the token band is completed to initiate a token service configuration request over the payment network.
And step 3: the mobile application then communicates with the SE via the global platform standard and securely completes the personalization of the payment token at the SE.
And 4, step 4: the token strap is removed from the token mooring and a passive token strap, which is not unpowered, is placed on an NFC enabled point of sale terminal that applies power to an antenna on the token strap to communicate with the payment applet and complete an NFC contactless payment transaction with the terminal.
Referring to fig. 4, a block diagram of a hybrid batteryless active and passive device according to a preferred embodiment of the present disclosure is shown, according to which the hybrid device for secure wireless payment comprises a secure element 1020 adapted to store at least one secure payment applet and at least one token for secure contactless payment and to be operatively connected with an active operation unit 1010 and a passive operation unit 1030. This embodiment differs from the embodiment shown in fig. 1 and 2 in that the active operating unit therein is preferably adapted to be engagably and detachably or detachably/decouplably connected with the safety element. For example, the active operating unit may be integrated with the power transfer unit and/or mounted or permanently attached to the hybrid/flexible board without the safety element and the passive operating unit.
The hybrid device is configured to be switchable between an active state and a passive state in response to operational requirements and conditions of the various operations required. In the active state, the active operating unit 1010 is activated and powered on demand, e.g. by an external power supply, to enable the hybrid device to function as an active device and to be suitable for various operations requiring a high and stable power consumption, in particular for providing the secure element with personalization information of a payment card and/or a payment token of the device. In this regard, the active operating unit enables the hybrid device to support end users in installing and loading third party applications to the secure element.
In the passive state, the active operating unit is deactivated and/or separated from the external power source, and the passive operating unit is activated/configured to enable the hybrid device to function as a passive device and to be suitable for various operations requiring relatively low or instantaneous power consumption/power, in particular for payment token authentication and/or contactless payment transaction operations by means of said secure element, wherein the low or instantaneous operating power may be obtained from a predetermined matching device adapted to work with the passive device.
In some embodiments, such as the embodiment shown in fig. 4, when in the active state, the active operating unit 1010 is activated by being operatively coupled with and powered by a power transfer unit 1060 for wireless data communication with a configuration unit, such as a dedicated machine, a computer with a dedicated module for configuring data to the secure element 1020, a smart or mobile device, for configuring personalization information of the payment card and/or payment tokens of the device from the configuration unit to the secure element.
In some embodiments, such as the one shown in fig. 4, when in the passive state, the passive operation unit 1030 is activated by being operatively coupled with the payment transaction unit 1050, such as with a dedicated machine terminal, with a computer, smart or mobile device having a dedicated module for contactless payment transactions with the secure element 1020, and is wirelessly powered by the payment transaction unit, so that payment token verification and/or contactless payment transaction operations can be conducted with the payment transaction unit through the secure element.
In some embodiments, the active operation unit comprises a first wireless communication unit adapted to couple with and wirelessly communicate data with the personalization information and payment token configuration unit. The first wireless communication unit is operatively coupled to a power receiving unit and/or a transient power storage unit, preferably an ultracapacitor, adapted to receive and/or store power from the coupled power transfer unit, in order to be able to perform routine and specific operations of the hybrid device requiring high and stable operating power.
In some embodiments, the first wireless communication unit is a WIFI, BT and/or NFC enabled communication unit, and preferably a BLE unit having a plurality of contacts (preferably 2 or 4 contacts), preferably waterproof and/or exposed contacts.
In some embodiments, the passive operating unit comprises a second wireless communication unit adapted to couple and conduct wireless data communications with the payment transaction unit and operatively coupled with the antenna unit to receive its operating power and payment transaction data and signals from the coupled payment transaction unit.
In some embodiments, the second wireless communication unit is an NFC enabled communication unit acting as an NFC passive target unit configured to draw its operating power from a payment transaction unit acting as an NFC initiator unit.
In other embodiments, the first wireless communication unit and the second wireless communication unit are both or the same NFC enabled communication unit, i.e. the first wireless communication unit and the configuration unit are both active mode NFC communication units, since the NFC device can operate in a peer-to-peer mode, which allows two active mode NFC enabled devices to communicate with each other for exchanging information in an ad hoc manner, wherein one device will deactivate its RF field while it is waiting for data.
In some embodiments, the antenna element comprises an antenna having dimensions of 10 x 24 mm. This size is quite desirable for stable and reliable data communication with the payment transaction unit without the need to incorporate an antenna booster to ensure proper operation of the passive operating unit as may be found in some prior art devices using smaller or miniature antennas. If the size of the antenna is large, the hybrid device may not be entirely built into some conventional wearable devices, such as conventional watches and jewelry worn around the wrist, waist or neck.
In some embodiments, the security element, the active operating unit and the passive operating unit are configured to be operatively coupled to each other and mounted on a bendable board/flexible board, which is adapted to be easily mounted on a non-planar or curved surface or to be easily inserted or embedded into a curved accommodation space; or the active operating unit may be adapted to be an external separate unit and removably connected with the safety element and/or integrated with the power transfer unit instead of being mounted on the bendable board/flexible board.
Referring now to fig. 5, shown is a block diagram of a hybrid batteryless active and passive device according to another preferred embodiment of the present disclosure, according to which the hybrid device for secure wireless payment comprises a secure element 1200 adapted to store at least one secure payment applet and at least one token for secure contactless payment and to be operable with a BLE enabled active operating unit and an NFC enabled passive operating unit.
In some embodiments, such as the embodiment shown in figure 5, the active operating unit is a BLE unit 1100 comprising a plurality of contacts for receiving power from a removably coupled power transfer unit, and the power transfer unit is a USB power transfer unit 1600 comprising a USB power transmitter, preferably equipped with connecting members, preferably connecting pins or hooks, for contacting and/or interlocking with said contacts of said BLE unit, thereby energizing the BLE unit for wireless data communication with a configuration unit, i.e. a smartphone 1400 as shown in figure 5. The passive operating unit is an NFC passive target unit 1300 which is operatively coupled with and wirelessly powered by a payment transaction unit, i.e. with the POS terminal 1500, and is configured to draw its operating power from the payment transaction unit as an NFC initiator unit for payment token verification and/or contactless payment transaction operations with said payment transaction unit through said secure element 1200.
Furthermore, in the hybrid device as shown in figure 5, the secure element 1200, BLE unit 1100 and NFC passive target unit 1300 are operatively coupled to each other and mounted on a bendable board/flex board 1700, which is adapted to be easily mounted on a non-planar or curved surface or easily inserted or embedded into a curved receiving space. Alternatively, the BLE unit is adapted to be detachably connected with the safety element without being fixedly mounted on the bendable board; and/or the BLE unit may be integral with the USB power transfer unit 1600, as will be described in further detail below.
In some embodiments, the hybrid device is mounted on and preferably embedded on or within a wristband or bezel buckle of a conventional watch, preferably made of a non-metallic material such as leather or plastic or the like to reduce interference therein, so as to replace the original wristband or bezel buckle of the user's watch for contactless payment transactions and other applicable operations, so that the user can wear and use the watch in a conventional manner while benefiting from the contactless payment functionality provided by the new and replaceable portions of the watch.
Referring to fig. 6, there is shown a schematic diagram of a watchband 6800 employing a hybrid battery-less active and passive device, wherein the power transfer unit is a USB power transfer unit 6900, generally in the form of a front portion of a clip or a clothes peg, according to a preferred embodiment of the present disclosure. The USB power transfer unit comprises an upper part and a lower part, on which are affixed a plurality of connecting pin or hook elements extending from the bottom of said lower part along a longitudinal axis and adapted to couple with corresponding contact elements provided in the bracelet. The USB power transfer unit may further comprise at least one securing or locking member (not shown) for contacting and/or interlocking with the contacts of the BLE unit. The power received through the contacts is used to activate an internal power source of a hybrid device embedded in the wristband for powering an active operating unit comprising a MCU and a BT/BLE unit operatively connected with the security element and the NFC unit. When in the passive state, the antenna of the passive unit will wirelessly extract its operating power from the external payment transaction unit to power the passive operating unit comprising the NFC unit operatively connected with the secure element and the antenna.
Referring now to figure 7, there is shown a schematic diagram of a watchband 7800 employing a hybrid battery-less active and passive device, wherein the power transfer unit is a USB power transfer unit 7900, also generally in the form of a front portion of a clip or a clothes peg and integrated with an active operating unit comprising a BLE unit and a MCU, according to another preferred embodiment of the present disclosure. In this regard, the active operating unit is removably connected with the security element and only the security element and the passive operating unit will be mounted on the flexible board and embedded in the wristband, and this configuration will greatly simplify the layout/layout and design of the hidden or concealed portion of the hybrid that will be mounted and embedded in a wearable device such as a wristband.
Similarly, the USB power transfer unit comprises an upper part and a lower part, on which are affixed a plurality of connecting pins or hooks extending from the bottom of said lower part along a longitudinal axis and adapted to couple with corresponding contacts provided in the bracelet. The USB power transfer unit may further comprise at least one securing or locking member (not shown) for interfacing and/or interlocking with the contacts to which the secure element and NFC unit are operatively connected. The coupling between the connection pin and the contact member is adapted to configure the personalization information of the payment card and/or the payment token of the device to the secure element via the external active operating unit. The contacts are adapted to enable power transfer and data communication between the external active operating unit and the secure element. In this embodiment, there are four contacts so that data and power signals can be transmitted simultaneously to facilitate operation of the active operating unit and the security element. When in the passive state, the antenna will wirelessly extract its operating power from the external payment transaction unit in order to power a passive operating unit comprising an NFC unit operatively connected with the secure element and the antenna.
