My project I made for my daughter using nfc tags and the dfplayer mini was a hit, so much that I’m getting requests from family members for birthdays, Christmas, etc. I’m glad everyone is happy with it, but with this many requests and the fact that its for children who will inevitably lose or destroy the nfc tags, I need a way to produce them in quantity. Right now I’m using the UID from each tag, unfortunately this requires reprogramming the xenon for a replacement, which is unrealistic.
I’ve searched for hours, through the forums and Google, but nobody seems to need to read the ndef data on a tag, or at least didn’t come up with a solution. So is there a way to write to multiple tags, and read that data with a PN532, using the adafruit library, to accomplish this?
