How can I edit the content of my smart card?

Question

Can you tell me please how can I 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

Thanks in advance! :)

Answer 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.
