Description
Technical field
The present invention relates to a kind of being input as and to read and write contact type CPU card, logic encryption card and contactless RFID radio-frequency card, be output as that portable thermosensitive is printed or the input-output device and the card reading method of the microminiaturization that integrates that the wireless blue tooth mode is exported.
Background technology
The portable thermosensitive printer is very general in all trades and professions are used, and is used for printing notice for payment of the fine as the traffic police, and logistics is used for printing joins the goods receipt, and water power is checked meter and is used for printing premium notice list etc.Some industries are the management level that constantly promote self, increase work efficiency the various users of distribution (management) card in the industry or this group, drive card as traffic, shop member cards etc., these cards have plenty of the CPU card or the logic encryption card of contact, have plenty of contactless RFID radio-frequency card.Because no card reading interface, the configuration mode of the PDA/ smart mobile phone+portable thermosensitive printer that generally uses in the application of today owing to can't Card Reader, can not satisfy application demand.
Print application scheme that can Card Reader has following dual mode at present:
1. use and print the Card Reader all-in-one:
This kind scheme is used the all-in-one that integrates Card Reader, printing, PDA function, and all-in-one itself uses the general-purpose operating system (as WINDOW CE, LINUX), as long as operation different industries application software just can be applied to no industry.
The advantage of this scheme: a machine can be finished all functions, and the system integration is comparatively convenient.
The shortcoming of this scheme: 1) all-in-one all is import at present, and price is very expensive, and large-scale promotion has certain degree of difficulty; 2) all-in-one is because integrated a lot of functions, and the unit volume is bigger, carries inconvenience.
2. use band card-reading function PDA/ smart mobile phone+portable thermosensitive printer:
The key of this kind scheme is to select the PDA/ smart mobile phone of a band card-reading function, mixes portable thermosensitive printer commonly used at present, uses bluetooth communication between the two.The data that PDA/ smart mobile phone Card Reader will need to print after handling send to printer, the printer output corresponding results.
The advantage of this scheme is closely similar with present application, and volume is also smaller.
The shortcoming of this kind scheme is to select very difficulty of a band card-reading function PDA/ smart mobile phone for use, even if choose certain PDA or smart mobile phone, can not satisfy the continuous variation demand of client, and to customize a such machine expense also be quite expensive to PDA/ smart mobile phone style, function.
Summary of the invention
The objective of the invention is: propose input-output device and card reading method that a kind of portable thermosensitive is printed, especially provide a kind of have input function, can read and write contact type CPU card, logic encryption card and contactless RFID radio-frequency card, the way of output is portable minisize thermal printing or a kind of input-output device by wireless mode output.On the basis of basic function, increase PSAM deck, user's deck with existing portable thermosensitive printer, and the RFID radio-frequency card reader.
The object of the invention also is: a kind of printing device with cipher key function of empowerment management is provided, guarantees that using all kinds of law enfrocement officials of this equipment is legal user, can be used as printer prints and go out legal law enforcement document, have the two function fully concurrently.If the data in the subscriber card have security requirements, the cryptographic algorithm that reads such data is just in the PSAM card.
Technical scheme of the present invention is: input-output device and card reading method that portable thermosensitive is printed, utilize the input-output device of the microminiaturization that input/output function integrates: the input-output device of described microminiaturization comprises the complete machine and the electric framework of portable thermosensitive printer, comprises microprocessor and needed storer, user's deck and PSAM deck, smart card reader chip and/or RFID Card Reader chip, bluetooth module and/or infrared module.The smart card reader chip connects user's deck and PSAM deck, is used to read and write the information of subscriber card.Described input mode is by PSAM deck and the user's deck (IC-card, magnetic card or RFID radio frequency Card Reader) that is used to read and write subscriber card are set.Other is provided with infrared and/or the Bluetooth signal input mode; Read-write is used to the input information reading and writing CPU card, logic encryption card or most of contactless RFID radio-frequency card and receive general PDA/ smart mobile phone during subscriber card; The described way of output is by minitype thermal printer printout or by the output of wireless blue tooth signal on paper is situated between; But any mode is exported, and also can two kinds of modes export simultaneously; And be that miniaturization integrates, become the equipment of a hand-held; Read-write CPU card, logic encryption card or most of contactless RFID radio-frequency card (following general designation IC-card) will promptly make the process initiation of read-write subscriber card through the authentication of PSAM card by the credit verification of PSAM card in the PSAM deck of authorizing.Data in the subscriber card have security requirements, and the cryptographic algorithm that reads user's data is just in the PSAM card, as des encryption algorithm commonly used.
The input-output device that portable thermosensitive is printed, the complete machine and the electric framework that comprise the portable thermosensitive printer comprise microprocessor and needed storer, user's deck and PSAM deck, smart card reader chip and/or RFID Card Reader chip, bluetooth module and/or infrared module and printer motor driver module, power-supply management system, man-machine dialog interface etc.Described microprocessor is 32 bit processors, is the core of entire equipment.
