multiple rfid reader arduino I have problems with multiple RFID (MFRC522) usage. I use the MFRC522.h library from GitHub - miguelbalboa/rfid: Arduino RFID Library for MFRC522, and I want to read 8 . When a debit or credit card has the contactless feature, it can be tapped or held near a contactless-enabled merchant terminal. Encrypted card information is then sent using near field communication (NFC) technology between the card and .Eva Lacalle. Hotel key cards, NFC, magnetic stripe and RFID cards are various kinds of cards that ease hotel room entry. They also offer a range of other functionalities – from increasing the average daily spend to providing .

I have problems with multiple RFID (MFRC522) usage. I use the MFRC522.h library from GitHub - miguelbalboa/rfid: Arduino RFID Library for MFRC522, and I want to read 8 .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 . I have problems with multiple RFID (MFRC522) usage. I use the MFRC522.h library from GitHub - miguelbalboa/rfid: Arduino RFID Library for MFRC522, and I want to read 8 RFID modules with one Arduino Uno, but I have managed only 2! I connect all the SPI pins, SS1 to pin10 and SS2 to pin2.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.
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 RFID.
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). How would I go about expanding this code to include 8 or more RFID readers per arduino? Is that even possible? My old code included a reset pin for the RFID readers.

This is a multiple RFID Readers system designed specifically for an Escape Room. The door will open after the 4 right cards (Tags) are read and recognized.
Is it possible to connect multiple RFID-RC522 readers to the same 3.3V, RST, GND, IRQ, MISO, MOSI and SCK pins if you use a different pin for each SDA? If so, this would save me a lot of pins. So far, I have only seen direction on how to connect one RFID-RC522 to an Arduino.You have successfully learned how to read multiple RFID tags simultaneously using an Arduino board. By modifying and expanding the code, you can develop more complex RFID systems to suit your specific needs. RFID (Radio-Frequency Identification) technology enables wireless communication between an RFID reader and RFID tags. The Arduino microcontroller is an excellent platform to manage multiple RFID modules due to .
These HEX bytes can be deciphered and recreated using an Arduino or other microcontroller if you need a particular capability or feature that is not supported in the SparkFun Simultaneous RFID Reader Arduino library.
