如何使用Android读取（和写入）Mifare DesFire卡

Question

I'm trying to read and write with an android app an mifare desfire card (classic works already) but don't know how it works :). I know it has something to do with transceive(byte[]) which is responsible for communicating through raw bytes but how does it work in detail? Can you give me some Code-snippets?

Thanks a lot and best regards.

Answer 1

恩智浦推出了一个SDK，以处理与Mifare DESFire EV1卡的通信： https : //www.mifare.net/en/products/tools/taplinx/

Answer 2

It is rather complicated than that, because all communication is ciphered and could also be with CMAC. I've found a high level SDK than does all the job so you don't have to deal with transceive and all that, private message me if you are interested..
