arduino rfid readers Hello everyone. As my title says I have a problem when I try to connect 5 RFID Readers (RC522) at my Arduino Uno. I am using the common MFRC522 Library by miguelbalboa. What I want to do is when I put the correct tags at each reader a relay activates. My problem is that when I put all the Readers together and power through my laptops USB the Readers don't . Because to simulate a card, the NFC Card Emulator needs to write the Card-ID to the NFC configuration file on your phone, which requires root privileges.) . If I stick an RFID card on the back of my phone it will continuously read the card .

3. Tap and pay at checkout. You can pay with your phone in stores anywhere you see the contactless symbol. To use your phone to make a payment, just tap or hold your device over the card reader and wait until you .
Using Arduino Programming Questions. stangists June 5, 2016, 10:47pm 1. Hy, 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 . Using Arduino Project Guidance. yesyes February 24, 2015, 12:55pm 1. Hi, I was wondering if there are any RFID readers for these RFID microchips that are implanted in pets. We have 2 chipped cats and the idea is to attach a reader on either side of the cat flap, which would allow me to check which cat is in or out.system October 10, 2010, 2:27pm 2. If you are only now at the hardware acquisition stage, I'd get two serial RFID readers and a Mega (with 4 hardware serial ports). Connect each RFID reader to a separate serial port, write a little code, and you're done. Depending on the RFID readers that you get, and thier range, you may need to consider some .

Then slide the two along side each other and see where they line up to find out what bits you have to exclude. hii all, I have been working on wiegand protocol Rfid readers..I can successfully read single rfid reader with single arduino by using wiegand library..the code is as follows: #include WIEGAND wg; voi.. Using Arduino Project Guidance. Brittio January 18, 2017, 4:24pm 1. I'm working on a project where I need to connect a maximum of 6 RFID readers to an arduino Mega. I used Miguelbalboa's github library, and built it off of his ReadUidMultiReader example. The program works reliably with the "credit card" style tags, but when i use the blue .
One RFID i connected like this: RFID Mega * RST/Reset 6 * SPI SS 7 * SPI MOSI 51 * SPI MISO 50 * SPI SCK 52 *. I tried connect second RFID in the same way, using this same reset pin, but changing SPI SS pin to 8 using the example of library MFRC522 ReadUidMultiReader, but didn't work (program can't find any RFID reader). I have no idea how .
Thank you for the response. Depending on the tag being read it but typically it has two read 12-16 characters. I think maybe the bank of pro mini's might be the best solution as they will then be able to store the ids found and transmit back when available kind of . Using Arduino Networking, Protocols, and Devices. Hi guys, I hope that you'll be able to help me. I made two differents prototypes using one arduino Uno. One with one RFID reader, one with three different RFID readers. They are both working fine. So I want now to move forward on a new prototype, with 9 differents RFID readers (type RC522) on a .
