Hello,
I want to make a small device using the Arduino that will connect to the phone using NFC. I want this device to be read by the phone like a passive chip (like a bank card for example) but the tag sent by the device will be different, it will gather in it the codes of several chips or cards that can be changed thanks to an interface on the Arduino.
I've never used NFC before, so I'd like to know if this is possible, and if so, which module I should use and where I should start.
Thank you in advance for your answers.
