multiple rfid readers spi bus arduino I have problems with multiple RFID (MFRC522) usage. I use the MFRC522.h . How to use Quick Share: Find the file, photo, or content you want to share. Tap on the Share button. Select Quick Share. Your device will start .There are many hardware features that can be important when choosing a credit card reader. However, the most important feature is compatibility with your Android device. The reader should connect to your device easily and be able to process payments quickly. Other hardware features that can be important . See more

You could ditch the Uno and buy an Arduino Mega, which has 4 hardware serial ports. Then you can connect both RFID readers to hardware serial interfaces, using the first serial interface for communication with the PC and still having one interface left. This would be my preferred way. So I want now to move forward on a new prototype, with 9 differents RFID readers (type RC522) on a arduino mega, I've updated my script (based on GitHub - miguelbalboa/rfid: Arduino RFID Library for MFRC522). By connecting multiple MFRC522 RFID readers to an Arduino Uno, she’s come up with a method of triggering a device (like an electronic door lock) only when the appropriate combination of. Multiple SPI devices on the same bus shouldn't be a problem. I would try the following steps to narrow down the problem: Add Pull-Up resistors to each CS line (10k should be enough) (The is no need for resistors on the MISO, MOSI .
RFID Readers: Multiple RFID readers, such as the MFRC522 or RC522, are commonly used with Arduino. RFID Tags : Passive RFID tags that match the frequency of the RFID readers (typically 13.56 MHz). Breadboard and Jumper Wires : For making connections between components.Example sketch/program showing how to read data from more than one PICC (that is: a RFID Tag or Card) using a MFRC522 based RFID Reader on the Arduino SPI interface. Warning: This may not work! Another option is to create an SPI object for each reader in your code and only change the MISO lines for each, keeping the same MOSI, SLCK and CS lines. Then selecting the boards to read from will change the MISO input and read from the correct board.
To read data from that RFID reader, use the Arduino's output pins as SPI chip-select signals so you can have all RFID readers on the same SPI port. (I didn't see the chip-select signal on the chip pin-out but I'm sure there is one.) I have problems with multiple RFID (MFRC522) usage.
