Description
Technical field
The utility model relates to a kind of RFID reader, particularly relates to a kind of RFID reader that is used for the near field payment.
Background technology
The payment of mobile phone near field is to utilize close range communication techniques to realize mobile phone and the contactless information interaction of consuming POS, to finish the novel modes of payments of both parties' monetary payoff process.Mobile phone near field payment is one of instrument of paying by mails, is a kind of brand-new means of payment of bank's magnetic stripe card, IC-card of continuing.At present, the close range communication techniques of mobile phone near field payment has two frequency range: 13.56MHz and 2.4GHz.The technical requirement difference of two frequency ranges, product form is also different.The intellective IC card that is applied as 13.56MHz that China is the most general, its range of application comprise Bank Danamon card, mass transit card, all kinds of member card and promotional card etc.; 2.4GHz technology is because the transmission of wireless signal needs continued power, and mainly at moving communicating field, its product form is the mobile phone wallet RFsim card of China Mobile.
The product form analysis of mobile phone near field payment is present, and China's mobile phone near field payment standard is also not clear and definite, and therefore, each money pool enterprise releases the pilot product one after another, adopts technology and external form mainly to be divided into two big classes, four kinds of forms according to product.One is based on non-external card, SIMpass card and three kinds of forms of NFC mobile phone that meet rf frequency 13.56MHz; Two are based on the non-RFID-SIM card that meets rf frequency 2.4GHz.Also have the non-modes of payments that connect such as two-dimension code identification, bar-code identification in addition.Using maximum mobile phone near field payments at present is the RFID-SIM card, and the RFID-SIM card is the product of double-interface smart card (rfid card and SIM card) technology to the field of mobile phones infiltration, is a kind of new SIM cards of mobile phones.The RFID-SIM card had both had the same functionality mobile communication of common SIM card, can carry out wireless near field communication by antenna and RFID card reader attached and on it again, thereby realize mobile phone on-site payment and identity authentication function.Yet the security performance that is used for the RFID reader only paid in the mobile phone near field at present is relatively poor, lacks client identity effectively identification and security control means.
Summary of the invention
The purpose of this utility model be provide in order to address the above problem a kind of safe, cost is low and simple in structure is used for the RFID reader of mobile phone near field payment.
The utility model is achieved through the following technical solutions:
A kind of RFID reader that is used for the payment of mobile phone near field, comprise housing, LCD display and button, central processing unit, data storage cell, the information security circuit, communicating circuit and label read/write circuit, the FPDP of described central processing unit respectively with described label read/write circuit, data storage cell is connected with described information security unit, described information security circuit is connected with described communicating circuit, described communicating circuit comprises antenna, radio circuit, special code coder of Miller and graceful Chester code coder, described antenna is connected with described radio circuit, and described radio circuit is connected with graceful Chester code coder with the special code coder of described Miller respectively.Described information security circuit comprises encrypting and decrypting device and authentification of message device, and described encrypting and decrypting device is connected with described authentification of message device.
Further, described RFID reader also comprises warning circuit, and the signal input part of described warning circuit is connected with the signal output part of described central processing unit.
Further, described RFID reader also comprises clock circuit, and the signal output part of described clock circuit is connected with the signal input part of described central processing unit.
Particularly, described data storage cell comprises interface circuit and storer, and described storer is connected with described central processing unit by interface circuit.
The beneficial effects of the utility model are:
The utility model adopts miller coding and graceful Chester sign indicating number to carry out information transmission, because miller coding and graceful Chester sign indicating number contain abundant clock information and have better anti-jamming capability, blocking up environment or ability to work in the interference environment takes place easily for improving read write line, simultaneously in the RFID reader, increased the information security circuit, can carry out client identity exactly and effectively discern.
