multiple rfid cards in one how do I write in multiple cards? The clumsy, but easy to write way is to write this section of code once for each card number. if (strID.indexOf ("89:E2:7E:CB") >= 0) //put your own tap card key; { Serial.println (""); Serial.println ("Authorized Access"); Serial.println (""); digitalWrite (A0, HIGH); delay (5000); digitalWrite (A0, LOW); } Surface Go for Business devices are equipped with support for near field communication (NFC), allowing users to take advantage of several common scenarios with the exception of NFC card payments. Applicable scenarios include: Passwordless authentication.

I keep my RFID cards separate by leading one in the catscard slot of my wallet and the other in the cash fold. As it is neither are strong enough to work from the inside of the wallet, so that might be enough separation depending on how thick your wallet is. how do I write in multiple cards?

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. 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.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 two cards that are allowed. But be warned: this code is rather ugly, don't use it in a productive environment. First: the String class should not be used on AVR Arduinos (memory fragmentation). 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.In this tutorial, we'll show you how to set up the SparkFun Simultaneous RFID Reader to take multiple, if not nearly unlimited, RFID readings simultaneously by connecting either the M7E Hecto or M6E Nano directly to your computer using a USB-C connection and running Universal Reader Assistant (URA) software, which provides a simple and . I've read about ISO14443A tags and that they should work with the RC522 RFID Arduino reader, however it's reading speed is slow. I have no need for a long reading range, quite small actually, all my tags are disposed separated from .
