NFC UID readers
Hi, I’m in the beginning stages of a project installation where when the audience enters they are given a small sculpture with an NFC chip inside (something like the NTAG213). They then tap their sculpture on a reader and that triggers sounds/video unique to their sculpture, and everyone’s contribution is composited in Max/MSP/Jitter.
I need 40 of these readers, and everything I keep coming up with recommends enterprise-focused readers that are like $70USD each — way out of budget for 40 of them. Can anyone recommend a simpler, cheaper, preferably off-the-shelf solution? All I really need is something that can read the UID from the NTAG and report it to Max and I can take it from there.
Search for Arduino RFID reader and you'll find units at around 3-7$, although they'll need to be connected to a controller like an Arduino, Raspberry or ESP32. Depending on your installation, you might be able to use one controller for multiple readers.
Thanks. What would be the criteria for using one controller for multiple readers?
