Abstract
The invention discloses an RFID (radio frequency identification) reader for near-field communication by a mobile phone. The RFID reader comprises a shell, an LCD (liquid crystal display), a key, a central processing unit, a data storage unit, an information safety circuit, a communication circuit and a tag reading-writing circuit. A data port of the central processing unit is connected with each of the tag reading-writing circuit, the data storage unit and the information safety unit, the information safety unit is connected with the communication circuit which comprises an antenna, a radio frequency circuit, a Millett code encoder and a Manchester code encoder, the antenna is connected with the radio frequency circuit which is connected with the Millett code encoder and the Manchester code encoder, the information safety circuit comprises an encryption and decryption device and an information authenticator, and the encryption and decryption device is connected with the information authenticator. The RFID reader has good anti-jamming capability; meanwhile, the information safety circuit is added into the RFID reader, so that identities of clients can be recognized effectively and accurately.
Description
Technical field
The present invention relates to a kind of RFID reader, particularly relate to a kind of RFID reader paying near field.
Background technology
It is to utilize close range communication techniques to realize mobile phone and the contactless information interaction of consuming POS that mobile phone near field pays, to complete the novel modes of payments of both parties' monetary payoff process.It is one of instrument of paying by mails that mobile phone near field pays, the brand-new means of payment of one of Shi Ji bank magnetic stripe card, IC-card.At present, the close range communication techniques that mobile phone near field pays 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 of what China was the most general be applied as 13.56MHz, its range of application comprises 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, the mobile phone wallet RFsim card that its product form is China Mobile.
The product form analysis that mobile phone near field pays is current, and China's mobile phone near field payment standards is also not clear and definite, and therefore, each money pool enterprise releases pilot product one after another, adopts technology and external form to be mainly divided into two large classes, four kinds of forms according to product.The one, based on non-external card, SIMpass card and three kinds of forms of NFC mobile phone that meet rf frequency 13.56MHz; The 2nd, based on the non-RFID-SIM card that meets rf frequency 2.4GHz.In addition also have the non-modes of payments that connect such as Quick Response Code identification, bar-code identification.Using at present maximum mobile phone near fields to pay is RFID-SIM card, and RFID-SIM card is the product of double-interface smart card (rfid card and SIM card) technology to field of mobile phones infiltration, is a kind of new SIM cards of mobile phones.RFID-SIM card had both had the functionality mobile communication that common SIM card is the same, 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.But the security performance of the RFID reader only paying for mobile phone near field is at present poor, lack effectively identification and security control means of client identity.
Summary of the invention
The object of the invention is to provide in order to address the above problem a kind of safe, RFID reader paying for mobile phone near field that cost is low and simple in structure.
The present invention is achieved by the following technical solutions:
A kind of RFID reader paying for mobile phone near field, comprise housing, LCD display and button, central processing unit, data storage cell, 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 telecommunication circuit comprises antenna, radio circuit, the special code coder of Miller and Manchester code scrambler, described antenna is connected with described radio circuit, described radio circuit is connected with the special code coder of described Miller and Manchester code scrambler 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 invention has the beneficial effects as follows:
The present invention adopts miller coding and Manchester code to carry out communication, because miller coding and Manchester code contain abundant clock information and have good antijamming capability, for improving read write line blocking up environment or the ability to work in interference environment easily occurs, in RFID reader, increase information security circuit, can carry out exactly client identity and effectively identify simultaneously.
