For starters, you need a pre-wired NFC RFID module as the key hardware. NFC and RFID projects have become a huge trend, but many modules are pricey for electronics hobbyists and need a complex setup.

The already-large family of Arduino boards is enriched with a new entry, the Arduino Nano RP2040 Connect, integrating the RP2040 microcontroller developed by Raspberry Pi Foundation with the u-blox ...
