Anybody here have experience with NFC tags and the hardware used to read them? Is there a way I can make my own readers so I'm not spending 50 bucks a pop?
So don't buy new phones then. But you'll have a really hard time find cheap 2nd hand phones with NFC readers.
And don't expect that you can rip out the readers and cobble 'm to an arduino
Tell first what the fuck you're trying to accomplish
