About the CPU card read and write operations-CodePudding

Which master did the operation of the contactless IC card, CPU card main need is to read and write operations, can give a description or source code

CodePudding user response:

I don't know the CPU card, but want to see what card reader, card reader has a different interface, card reader, today

CodePudding user response:

Specific see card reader manufacturers provide the interface dynamic link libraries, generally contact manufacturers can get the dynamic link library and documentation, some vendors may be packaged directly, and the pattern of events or news via the corresponding function interface directly application, some vendors may be provide a bunch of function interface, from the open communication port (COM or USB), to the polling data read, to close port, etc., in simple terms is similar to a serial port communication application, specific can consult online a lot about the source program of serial port communication,

CPU card used ACR38 card reader,
If you just read and write COS that is simple,
Under the query winscard. DLL data (Windows's own)

n you have winscard. DLL data, give me a copy

CodePudding user response:

Buy it CARDS and card reader, don't even offer a demo?
The worst will provide a card read instructions?
I don't know you use the card, didn't send help to you,

Lch0422 give some instructions, these functions is what ah?

CodePudding user response:

Lch0422 how are you, my email is [email protected], have detailed instructions to send me email, thank you,

CodePudding user response:

Also please know ~

CodePudding user response:

Different manufacturers internal protocols are different

CodePudding user response:

Don't know the building to find a way,
Have the data, pass me a also, recently the company also to do card reader in terms of function,,
Hope to have information can send me a

IC card CPU card read and write functions is different, depends on reading and writing
