The easiest solution to your problem is to connect your MFRC522 to an Arduino nano each. Then you can talk between the raspberry and the 3 arduino using I²C. Moreover you are able to stack 256 RFID readers using this technique. You have various options how to connect two of these chips to the RasPi: - both on UARTs (additional UART needed), - both on I2C, - both on SPI, - one on UART, one on I2C, - one on UART, one on SPI, - one on I2C, one on SPI. From software perspective, it would make sense to connect both chips using the same interface type. Here's a new solution using a resistor and a FET to parallel multiple RC522 RFID readers. I tried UART interface without success, and I2C is too short range. Using SPI code from https://www.raspberrypi-spy.co.uk/2018/02/rc522-rfid-tag-read-raspberry-pi/ .

Using serial connected radios, you can have multiple arduinos listening and replying to one Pi (and far away depending on the radio). The devices you want to use (RDM6300) are 'dumb' and will just send a data stream over serial if a card is waived near them. For my project, I need to use four RFID readers (the ID-20LA Innovation). Each one needs their own tx/rx pins. Can anyone suggest any pi hats/bonnets or thoughts on how to wire these up? In this Raspberry Pi RFID RC522 tutorial, I will be walking you through the steps on how to setup and wire the RFID RC522 chip with your Raspberry Pi. This guide shows how to connect an RFID RC522 to a Breadboard and then to the Raspberry Pi's GPIO Pins, although you could also wire the components straight to the Pi. Simply connecting 7 of the Raspberry Pi's GPIO pins to the RFID RC522 reader is .
