Hi, I'm looking for some advice on whether something like this would be possible. Any advice is welcomed, thanks!
I'm wanting to emulate a MiFare Classic 1k card on an Arduino so I can change the UID it is sending out and the data on the card without having to flash or clone a card.
So basically, can I make a circuit similar to one in a smart card that would allow Arduino to broadcast an 13.56Mhz RFID or NFC signal through an antenna? And with my choice of data on that signal?
