Hello Everyone,
I need to read and write Mifare 1K tag.
I currently be able to read UID of the tag, but in the NFC library I have not found nothing to deal with KEY A , KEY B authorization and read/write blocks.
I've to build to myself a libray to this task or is possible to manage reading and writing MIFARE 1K tags direcly from some B4A library?

Thanks a lot for the attention.

The NFC lib gives you the possibility to communicate with a NFC Tag.
A specific Protocol (like the one you want to use) you need to implement by yourself.
