The utility model content
The utility model provides a kind of passive magnetic card reader, it mainly is to solve the existing in prior technology digital product with the built-in chip type of swiping the card, mobile phone cost and weight have been increased, when not needing function of swiping card, can't remove, and this chip of swiping the card can't be applied to the technical matters of all digital products etc.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of passive magnetic card reader of the present utility model, comprise the card reader body, it is characterized in that described card reader body interior is provided with controller and demoder, one end of card reader body is provided with the plug that can insert the digital product audio interface, and the other end of card reader body is provided with the chute magnetic head that can read magnetic card.The utility model is passive card reader, only needs to connect the audio interface of mobile phone, utilizes the audio frequency input that data on magnetic card is delivered to the technology that mobile phone is finished Card Reader.The plug of one end of card reader body can be changed according to the audio interface of different model digital product, to be applicable to different digital product models.The chute magnetic head is general can directly read the magnetic head of magnetic card content.Only need to be stuck in to slide in the chute, the data of magnetic card promptly can be input in the digital product by the intrinsic demoder of card reader, controller.Plug, chute magnetic head can be located at the two ends of card reader body, also can be located at the both sides of card reader body.
As preferably, described card reader body interior is provided with the magnetic card demoder that is connected with the chute magnetic head, and the magnetic card demoder is connected with shaping circuit, modulation circuit in turn by circuit; The card reader body interior also is provided with audio frequency input circuit, the audio output circuit that is connected with plug, the audio frequency input circuit is connected with modulation circuit, audio output circuit is connected with modulation circuit, energy recovery circuit respectively, and energy recovery circuit connects shaping circuit, magnetic card demoder respectively by circuit.
Card reader obtains energy from audio output circuit, does energy at the energy recovery circuit place and recovers, and produces the electric energy greater than 3mW, supplies with the decoding work of magnetic card demoder, and through the processing of shaping circuit, the control modulation circuit sends the ASK modulation code stream of 300BPS.
Energy recovers to adopt 0 bias voltage field effect transistor full-wave rectification, with minimal losses, obtains ceiling capacity, adopts the high efficiency dc-to-dc transducer then, obtains stable power.
The chute magnetic head is small-sized magnetic card card-reading magnetic head, and the magnetic card demoder is a low-power consumption magnetic card demoder, adopts MCU or mimic channel, reads the decoded data of demoder, as the control signal of modulation circuit.
Adopt audio output signal as carrier wave, can further reduce the power consumption of equipment, make equipment oneself not need to produce in addition carrier wave.
Modulation circuit adopts the ASK modulation, can simplify circuit structure to greatest extent, reduces energy consumption.
Audio output circuit can use any audio frequency more than 900 hertz, typically supplies with the audio standard sinusoidal signal of 2K.
As preferably, the width of described card reader body is the width of digital product not quite, thereby can not influence the use of mobile phone.
Therefore, the utility model only need utilize the audio interface of card reader linking number code product the audio frequency input data on magnetic card is delivered to digital product and finish Card Reader, digital product can be used as the POS machine and uses, characteristics such as passive operation is removed the trouble of changing battery from, only is connected with audio port, and is easy to use.
