Can we use RFID modele with Electric Imp?

Can we use PN532 ( ) library to communicate with RFID module instead of NFC?

RFID module

The device you link to uses an NXP MFRC522, so it’s from the same company as the PN532. They ought to be similar, but you’d need to try it out to be sure of that. We have not done so.

We don’t have a library for the MFRC522 (all of our hardware libraries are listed here), and I don’t believe there are any plans to produce one (though that would change if a customer requested assistance with this). That said, even if the PN532 library doesn’t work with the MFRC522 fully, it should give you a good basis to begin creating code for the latter.
