Good morning, everyone. I’m new to this forum and to the world of Arduino.
I’m starting to get very interested in all of the different applications you can do, and it’s really cool.
I decided to start with a basic kit to familiarize myself with the tools.

My goal, however, will be to use Arduino with RFID / NFC.

I’ve seen some help on the various tutorials and examples, but I’d like something a little different.

Is it possible to connect more than one RFID RC522 board to a single Arduino and have them all read the same NFC?

I would have to connect about 10 of these cards and when one of these cards detects the presence of the tag, it turns on a different led.

Dear sir,

The RFID module available on market which is RC522 (MFRC522) module is based on SPI port. One pin on SPI port is slave select or SS which is used to select a particular module by a pin and use that to read cards. Please refer to widely used Github library for arduino https://github.com/miguelbalboa/rfid .

However RC522 is not fully working with NFC. NFCs are just a step ahead of RFID in technology. However there are PN532 modules in market and you can use those with Arduino. Goodluck
