Can you tell me please how I can edit the content of my smart card?
How should I use APDU commands in order to edit the content?
Lets say I have something like this on a smart card:
00 00 05 00 00 00 00 00 00 00 00 FF FF FF 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00
And I want it to be :
00 00 06 00 00 00 00 00 00 00 00 FF FF FF 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00
How can I do that? Is it possible? If yes, how?
I have ACR-122 NFC READER/writer
回答1:
You're talking about simple Mifare tags apparently?
ACR122 has its own API manual for wrapping the RFID in the CCID frames to talk to tags, first have a look at this.
It also contains practical examples with mifare data tags.
