Requirements

- @pokusew/pcsclite for actually communicating with the tag (see examples).
- On Linux, you may also need:
- apt install libpcsclite-dev pcsc-tools
- In case you have a ThinkPad with a built-in reader, it might conflict with libpcsclite. This may help: https://stackoverflow.com/a/66558992
- This library was tested with the reader Alcor Micro AU9540
- You can use crypto.hkdf (builtin) or nistkdf-800-108 for key diversification/derivation.
- ndef to parse and create NDEF messages
