Hey! this is a wicked video TYSM so it looks like each RFID reader use the same digital pins in the Arduino, can you add say up to ten RFID readers to this configuration?

For those struggling with having several readers. I had the same issue and had to check 2 things: 1 - that the reset should go to the right pin, 2 - that I had good connection on all pins. If you have some resistance, it means the connection is not great and it will probably not work. I had to dish the jumper wires I had and get some good connectors. In doubt, test the resistance to see how good you connection is.

Excellent project. I am looking to develop a project with two MFRC522 readers in which i need to display the uid of the card and which reader is reading the card (Either card 1 or 2). Is my usecase possible with 2 rfid reader and esp32?

Oh my god, I was looking for this video my whole life! :( I was desesperate to find a correct wiring diagram and explanation, thank you so much! I have a plan to make a plan where the players should move the job. It is the successive activation of the readers in a certain order that allows the opening of an electromagnet. I am still very far from having succeeded..! One question, are you French? :) J'ai vu que le livre était en français :3

Hey awesome project! in ur code you use: {0x4B, 0x17, 0xBC, 0x79}, {0x8A, 0x2B, 0xBC, 0x79}, {0x81, 0x29, 0xBC, 0x79}, {0xE6, 0xDF, 0xBB, 0x79}, How does this work and how can I change this into the numbers of my cards?

Il semble que le fonctionnement dépende des lecteurs. Alors que tous semblent identiques, avec certains ton montage ne marche pas du tout car il y a confusion sur les MISO. En fait, quand tu branches 2 modules SPI ensemble, tu as MISO, MOSI et CLK qui sont communs (comme sur ton schéma). Or avec certains modules RFID, le MISO commun fait qu'un seul module fonctionne. La solution semble être d'avoir des MISO séparés. A priori cela peut marcher avec la librairie Sunfounder.

Some people all over the internet face issues when connecting multiple RFID boards in parallel to Arduino board. When 2+ readers connected it stop working. One reader works perfectly but 2+ pcs. not. The problem is weak MISO output of some reader board. Checked some Russian electronics forums and found answer how to make multiple readers work. You need to connect MISO outputs through the OR logic gate to Arduino. It is possible to use logic OR IC chip or just simple diodes+resistor OR element. Connect anodes of diodes to MISO reader outputs. Then tie all cathodes together, put 4k7 resistor to the ground (yeah we just built OR logic gate) and then connect to the MISO pin 12 (on Arduono Uno). That's it! Tested with 3 readers. Work like ice ;)

Another issue with multiple boards on one Arduino is that with some of these RFID boards the MISO line does not go high impedance when not addressed. It remains high and prevents other boards from communicating. I found this problem with low cost boards I bought on Amazon. A simple fix is to use a Tri_sate buffer (74AHC125) and connect each of the inputs to the MISO line from the RFID boards. Connect the outputs together and then to the MISO pin on the Arduino. Finally connect the chip select line for each of the RFID lines to corresponding Output enable pin on the buffer. This worked well for me.

What if you want each reader to open a different door? Like in an office situation
@annaane8817

If you want each reader to open a different door, you just need to add as much relays as the doors you have and then make a test loop on the Card ID so it opens that specific door and not another one.

sweet, I was looking for an example with multiple RC522 readers. Exactly what I needed. PS: haven't tried your setup, but from reading the code it looks like one can easily cheat the system by simply tapping/removing the same card 4 times as it only counts the number of valid recognised tags

with this code not only does the order not matter, but you can swipe the same valid card 4 times in any sensor and the gate would open, so keep that in mind while watching this

Thanks for uploading this. Small issue though, it is possible that the same RFID card can be used multiple times on the same RFID reader to get the door to open. The code does not check if a card has been used before, or if the card is used on a specific reader.

Hello agghanim, thanks for your comment. In fact, yes, you are right. I'm aware of the issue but as I said before, in the real life usage, the rfid card is held on a certain object that has a certain form due to which it can be put on only one the reader, that's why I didn't really bother going further in the programming. But thanks again for your comment, I'll find some time to fix the issue. Cheers!
