Description
Technical field
Technical field is read and write the present invention relates to a kind of IC-card.Specifically related to a kind of Non-contact IC card reading/writing device, this hair
It is bright to be related to a kind of method that non-contact IC card read-write is carried out using Non-contact IC card reading/writing device.
Background technology
Non-contact IC card is applied in many technical fields at present, correspondingly needs to set this for reading and writing
The read-write equipment of non-contact IC card, and the communication between these read-write equipments and main frame (such as computer or PDA handheld devices)
Network is carried out by wired modes such as wire cable or surface-mounted integrated circuits.
Read-write as shown a kind of identity card of the prior art (a kind of certain types of non-contact IC card) in Fig. 1
Device, as shown in figure 1, the read-write equipment has a host machine part, is provided with host computer control module and short distance in host machine part
Penetrated from wireless communication module reception, transmission, control section, and Ministry of Public Security's standard identity card read-write module and non-contact IC card
Frequency interaction Anneta module.Wherein host computer control module is received by host circuit and short-range wireless communication module, sent, controlled
Part is connected；Short-range wireless communication module is received, sent, control section is read and write by Ministry of Public Security's standard identity card module for reading and writing
Telecommunication circuit is connected with Ministry of Public Security standard identity card module for reading and writing during module；Short-range wireless communication module is received, sent, control
System part interacts Anneta module with non-contact IC card radio frequency by the circuit in main frame and is connected.And non-contact IC card radio frequency is handed over
Mutual Anneta module is interacted with contactless IC card by radiofrequency signal.
Thus, in Fig. 1 the scheme of prior art by Ministry of Public Security's standard identity card module for reading and writing and host computer control module collection
Into together, but the main frame such as the volume of Ministry of Public Security's standard identity card module for reading and writing and existing handheld communication devices compares volume
