Implement NFC

[chris1howell]

Implement NFC/RFID Read, Write and authenticate.

Add ability to read NFC tag and authorize based on a locally stored tag.

Developers tool - Add ability to write to NFC tag and store tags that are authorized locally.

Future OCPP Add ability to read tag and pass tag via OCPP for authentication. Accept or reject tag based on response from OCPP server.

I plan to start working on this with a common PN532 chip and PN532.h libraries over I2C (connected to Huzzah).

Example code:
NFC on 8266

I agree I would love this. This would be great for keeping the charger from activating until the owner returns or if I want to keep track of how much a renter uses. It is too bad that there has not been any activity in the last four years on this.

The feature is available on a ESP32 version 4.x development release here:
https://github.com/OpenEVSE/ESP32_WiFi_V4.x/actions/runs/2045138078
It will soon be merged into the stable releases.

ESP8266 2.x is no longer supported or under development.

Thats amazing. Is there any documentation on how it works, and configured? Are there RFID modules for sale?
