technical field

The invention relates to a mobile phone shopping and payment technology in the financial field and the mobile communication field, in particular to a mobile phone shopping payment method based on NFC communication technology.

The invention also relates to a short-distance shopping solution for mobile phones that can be done with just one post.

The present invention also relates to a series of software implementations of a short-distance shopping system for NFC mobile phones that can be done with just one post.

Background technique

NFC is essentially similar to existing Wi-Fi and Bluetooth, but NFC uses a frequency of 13.56MHz, which is the same as the frequency used by the currently popular non-contact smart card ISO14443, so the mobile payment market is dominated by NFC technology. The territory to be dominated. And NFC itself has master-slave two modes of operation, that is to say, the device embedded with NFC chip can be used as a payment tool instead of a card, and can also be used as a payment terminal to play the role of POS.

Like RFID, NFC information is also transmitted through electromagnetic induction coupling in the radio frequency part of the spectrum, but there is still a big difference between the two. First of all, NFC is a wireless connection technology that provides easy, safe, and fast communication. Its transmission range is smaller than that of RFID. Low consumption and other characteristics. Second, NFC is compatible with existing contactless smart card technology and has become a formal standard supported by more and more major manufacturers. Thirdly, NFC is also a short-range connection protocol that provides easy, safe, rapid and automatic communication between various devices. Compared with other connection methods in the wireless world, NFC is a close-range and private communication method. NFC plays a huge role in the fields of access control, public transportation, and mobile payment. At the same time, NFC is also superior to infrared and Bluetooth transmission methods. As a consumer-facing transaction mechanism, NFC is faster, more reliable and much simpler than infrared. Compared with Bluetooth technology, NFC is oriented to close-range transactions and is suitable for exchanging important data such as financial information or sensitive personal information.

The NFC mobile phone has a built-in NFC chip, which can be used as an NFC passive tag—for payment; it can also be used as an NFC reader—for data exchange and collection. This function of the chip can be fully utilized through software design. NFC technology supports a variety of applications, including mobile payment and transactions, peer-to-peer communication, and information access on the move. Through NFC smartphones, people can connect with the entertainment services and transactions they want at any place, any time, and through any device, so as to complete payment, obtain poster information, etc.

Mobile payment, also known as mobile payment (Mobile Payment), is a service method that allows mobile users to use their mobile terminals (usually mobile phones) to pay for the goods or services they consume. In the future, mobile phones will integrate functions such as bus cards, bank cards and keys to pay for some daily services and facilitate citizens to travel and shop. This technology is already very mature abroad. This will greatly improve the quality of life of the public and make travel more convenient. Mobile payment technology realizes the entire mobile payment value chain, including mobile operators, payment service providers (such as banks, UnionPay, etc.), application providers (buses, campuses, public utilities, etc.), equipment providers (terminal manufacturers, card suppliers, chip providers, etc.), system integrators, merchants and end users.

Android is the name of Google's open source mobile phone operating system based on the Linux platform. The platform consists of an operating system, middleware, user interface and application software, and is the first to be built for mobile terminals. The system provides support for Near Field Communication (NFC) technology, and provides a set of standard APIs for applications to read and write access tag technology. The present invention adopts the smart phone equipped with the Android operating system to carry out the design and realization of the scheme, so as to meet the practical application of most users.

Contents of the invention

The realization of the present invention requires four hardware parts to provide support: an android smart phone terminal with an additional NFC chip, an NFC reader, a "commodity display wall" and a server, and the present invention is based on the NFC tag reading and writing program, mobile phone and NFC reader P2P communication program, commodity and customer information management system, and solutions for the realization of the shopping process.

Users need to hold an Android terminal with an NFC chip and load our host computer software. The service object facing the user is a "product display wall" with printed products and payment areas. The back of the "display wall" product introduction information also needs to be attached with NFC tags to record product information. The NFC tag is written and updated by the NFC tag reading and writing program written by us. The payment area needs to have a fully functional NFC device for exchanging data. The upper end of the commodity display wall is connected with the network payment server. By making full use of the android API, design NFC applications, complete the identification and processing of NFC tags, and short-distance communication with NFC devices to complete the transaction function.

Technical scheme of the present invention is realized through the following steps:

Step 1. Users with NFC mobile phones can register on websites that support NFC short-distance shopping. The registration content includes the user's usual address, the IMEI serial number of the NFC mobile phone, and the user's virtual account, which means binding the user to the mobile payment terminal device ;

Step 2, start the NFC module of the smart phone in the wireless and network options in the system settings;

Step 3, run the NFC application program installed on the smartphone to enter the shopping cart interface;

Step 4, the smart phone with built-in NFC chip scans the NFC tags corresponding to each product to be purchased on the "product display wall" in turn;

Step 5, on the NFC application program interface, the name, unit price, and quantity of the commodity appear, and at the same time, the total price and the payment switch button are displayed on the top;

Step 6. In step S5, click on any column in the product list, and the product details, buyer comments and promotion interface of the product will appear;

Step 7. Click the payment button on the mobile phone, approach the NFC reader in the payment area on the "commodity display wall", establish an NFC P2P connection with it, and send a payment request to it through the NFC signal;

Step 8, the NFC reader/writer transmits the order data to the server to verify the identity of the user;

Step 9, if the verification in step S8 fails, an error message is returned, and if the verification is successful, a payment success message is returned to complete the order transaction;

Step 10, the commodity seller delivers the commodity to the paid buyer.

The invention makes up for the defects of online shopping in daily necessities, and proposes a short-distance shopping technical solution based on NFC and mobile terminals. The solution will introduce near-field communication technology to achieve the purpose of convenient remote shopping, and truly realize that people can connect with the services and transactions they want through devices at any place and any time, so as to complete payment and obtain posters Product information, etc. Using the latest Android system to support NFC, develop NFC applications on Android phones, so that every Android phone with NFC function can become a smart terminal integrating shopping and payment.

In order to solve the leakage of user passwords, the present invention proposes a "one-post" mobile phone payment scheme. This solution uses the IMEI serial number of the mobile phone for device identification, abandons the traditional payment methods, including the emerging online payment, and changes the "input password" to "one post", opening a new path for portable payment and micropayment aisle. It saves users from worrying about password theft.

The invention enriches the function of the "carry-on" mobile phone as a shopping "identity card" and promotes its development. It fully combines modern humans' dependence on mobile phones (that is, "carry") with the "recognition" of NFC near-field communication technology and its "short recognition distance" characteristics. Enriching the functions of the mobile phone makes the mobile phone more like an "ID card", reducing the possibility of the mobile phone being "cumbersome". Turning the "short distance" short-board of near-field communication into an advantage, so that it will no longer be the object of criticism.
