This crate is work in progress and may permanently damage your tag. Also, the interface WILL change. Use with care (especially write methods), at your own risk!
This crate implements basic Mifare operations - Authentication and Reading. It's designed to be reader-agnostic so in order to use it, you just need to impl NFCTag for YourType. However, it already has impl for PN532 reader (enabled via feature with_pn532).
