I’m trying to find the best hardware and library to implement a production ready rfid detection.
I implemented a RC522 chip with the following library: https://os.mbed.com/users/AtomX/code/MFRC522/?utm_source=platformio&utm_medium=piohome
The RFID detection takes random time, from 1s to 10s sometimes, with the need to move the card in multiple direction before it’s detected. I’m looking for something instant (less than 1s) and not random.
I can only find posts before 2015 and mainly on cheap hardware or old versions of MbedOS. What would be a production ready and modern architecture?
