Question

USB Smart card reading

Asked by: orapb

I have EZPU100 smart card reader connected to my PC with all drivers loaded and tested successfully. Now I want to read data in smart ard using either powerbuilder or java gui. Anybody has some sample code? I have CASMCARD.DLL supplied by manufacturer but documentation is not clear and powerbuilder doesnt have exact equivalent for API function arguments. I can use WINSCARD.DLL of Windows but the same problem exists.

Thanks

You need to use JNI for this to be able to communicate with the DLL provided by the vendor of the device. Might be better to use JNI Wrapper so that some of the native JNI-related intricacies are handled by it and you are presented with an OO interface to deal with. www.jniwrapper.com Otherwise, if its a serial device which gets connected through the COM port, you can directly use Java Comm to communicate with the device (by-passing the DLL) if you know how to interpret and parse the data.
