I'm new to Arduino so I'll try to keep this short and to the point.
Setup 2 Arduinos that can share small [preset] data packets via NFC or RFID. Similar to a "bump data transfer."
I assume I would be able to equip each Arduino unit with a reader as well as a tag
I'm unsure of any sane way to accomplish this task without the host device also reading its own tag. Is there a more obvious approach I am overlooking? I do not want to use Bluetooth as I want this to be a close range action.
