Description
Technical field
The present invention relates to financial payment instrument, relate in particular to a kind of contactless financial payment terminal.
Background technology
Radio-frequency (RF) identification (RFID) technology is a kind of noncontact tag information identification transmission technology, carries out contactless bidirectional data communication with wireless radio frequency mode, reaches the object of target identification and exchange data.
At present, market is progressively proposed a kind of contactless financial payment terminal based on RFID technique, adopts radio frequency Card Reader chip to carry out the modulation and demodulation of radiofrequency signal.This technology Problems existing is: payment terminal function is relatively simple, and current interface is abundant not, can not be applicable to various communications protocols, and prior art radio frequency Card Reader chip realizes the integrated high cost of multi-communication protocol by force simultaneously.
Summary of the invention
The utility model provides a kind of contactless financial payment terminal, is intended to make up the problems referred to above.
The technical scheme that the utility model adopts is as follows:
A kind of contactless financial payment terminal, comprise control module, LCD cell, encryption/decryption element, push-button unit, communication unit and card reading unit, described LCD cell display payment terminal information, described encryption/decryption element realizes the data encryption and decryption of payment terminal, and described push-button unit realizes the information input of payment terminal, described communication unit realizes the data interaction of control module and other equipment, and described card reading unit realizes the exchanges data between control module and radio-frequency card;
It is characterized in that: described card reading unit comprises modulation circuit, power amplification circuit and antenna, many detecting circuits of at least 2, and the amplifying circuit corresponding with each bar detecting circuit;
Described control module exports card reading unit by after Card Reader command code, is modulated by described modulation circuit and high frequency carrier, and after modulation, signal is gone out by described aerial radiation after described power amplifier amplifies; Described antenna receives the return signal of radio-frequency card, carries out detection by described detecting circuit to return signal, and described amplifying circuit carries out filter and amplification to the signal after detection, is sent to the decoding that described control module completes baseband signal.
The technical scheme of further improvement is: described communication unit comprises USB interface and blue tooth interface.
Compared with prior art, technique effect of the present invention is: the structure changing whole card reading unit, instead of radio frequency Card Reader chip with modulation circuit and detecting circuit respectively and modulation and demodulation function is realized to signal, when antenna receives the return signal of the radio-frequency card of different communication protocol, by detecting circuit and the amplifying circuit of correspondence, signal is returned to the different input ports of control module, reach the object that payment terminal realizes multi-protocols read-write.

Embodiment
The present invention will be further described for the embodiment of showing below in conjunction with accompanying drawing.
As shown in Figure 1: contactless financial payment terminal of the present utility model: comprise control module 1, LCD cell 2, encryption/decryption element 3, push-button unit 4, communication unit 5 and card reading unit 6, described LCD cell 2 shows payment terminal information, described encryption/decryption element 3 realizes the data encryption and decryption of payment terminal, described push-button unit 4 realizes the information input of payment terminal, described communication unit 5 realizes the data interaction of payment terminal and other equipment, and described card reading unit 6 realizes the exchanges data between control module 1 and smart card.
As shown in Figure 2: the payment terminal of prior art, radio frequency Card Reader chip 7 is outputted to after control module 1 is encoded by protocol command, the signal madulation carrier wave will accepted by radio frequency Card Reader chip 7, signal after modulation is amplified by power amplification circuit 62, eventually through antenna 63, carrier energy and protocol command is radiate; When antenna 63 receives the feedback signal of radio-frequency card, by bandwidth-limited circuit 8, amplitude attenuation is carried out to this signal, output signal is delivered to radio frequency Card Reader chip 7 and carry out demodulation, digital signal after demodulation is sent to control module 1 by radio frequency Card Reader chip 7, control module 1 receives this signal, complete protocol analysis, realize the telecommunication with radio-frequency card.
As shown in Figure 3: the card reading unit 6 of embodiment 1 of the present utility model comprises: modulation circuit 61, power amplification circuit 62, antenna 63, three detecting circuits 64, and the amplifying circuit 65 corresponding with each detecting circuit 64.
Control module 1 exports after Card Reader command code, is modulated by modulation circuit 61 and high frequency carrier, and after modulation, signal is radiate by antenna 63 after power amplification circuit 62 amplifies;
Antenna 63 receives the return signal of radio-frequency card, according to the communication protocol that this radio-frequency card adopts, carry out detection by detecting circuit 64 pairs of return signals of correspondence, the signal after corresponding amplifying circuit 65 pairs of detections carries out filter and amplification, is sent to the decoding that described control module 1 completes baseband signal.
The superiority of the technical solution of the utility model is: prior art carries out the modulation and demodulation of radiofrequency signal with radio frequency Card Reader chip, because radio frequency Card Reader chip technology realizes that various communications protocols is with high costs causes existing card-reading terminal function comparatively single.The utility model structurally achieves the signal madulation of transmitting terminal and the signal receiving of receiving end respectively with modulation circuit and detecting circuit, instead of the function of radio frequency Card Reader chip.When antenna receives the return signal of the radio-frequency card of different communication protocol, by detecting circuit and the amplifying circuit of correspondence, signal is returned to the different input ports of control module, realize the object of multi-protocols read-write.Make financial payment terminal can meet the use of the radio-frequency card of various communications protocols simultaneously.
