How to setup a Raspberry Pi RFID RC522 Chip

In this video, I go through the steps of setting up the RFID RC522 chip with the Raspberry Pi.

The process of getting the circuit wired up correctly is pretty straightforward. There are seven pins that you will need to wire to the Raspberry Pi.

To start this tutorial, you will need a few pieces of equipment. I have listed everything you will need right below.

Raspberry Pi 2, 3, or 4

Micro SD Card

Power Supply

RC522 RFID Reader

Breadboard

Breadboard Wire

To ensure that you won't run into any issues, you need to make sure your RFID reader is the RC522 model. Other models might work, but I can't guarantee it.

You may also need to solder some header pins to the RFID chip as many of them don't have them already pre-soldered.

The code is pretty straightforward and will take you through the basics of interacting with the chip. Such as reading and writing to the RFID chip.

I hope that this video on the Raspberry Pi RFID RC522 chip helps you with your project. If you have some feedback, then please don't hesitate to leave a comment below.

Great video. Glad you're back. I do miss the old talking videos though. Keep it up!

hello,
great project ! i have managed to complete the project up until the attendance is being recorded. As i am not using a LCD scrren i have struggled to apapt and execute the script to write data to my database. Is there a script available that allows this without using the lcd screen ?

[kittenseather]

when i try to write it the tag it stays stuck on the "place your tag to write" part. I've tried placing multiple tags on the reader but none will write. Advice?

I own a Velleman vma 405 rfid reader. Can i use it with the mrfc522 library?

I have in errors when trying to use pip3 to install spidev

[benjamingeit]

Great Video, everything worked womderfully. I'm just wondering whether it would be possible that my password is written for example in an open text document, when I use the RFID chip?

Awesome!! Can you pls do another tutorial for RPi & Nokia 5110 Display?

[Iggyme]

im getting errors saying the channel is in use please set gpio to false i did that and it didnt work

[anonymeranonymer]

Do i need an additional RFID reader for every single card/chip ?? Iam asking because there are several RFID reader delivered.

[XWRKS]

card and token which came with rc522 in package already have a code, and seams like I can't delete those by writing new one. no idea what to do. Please help.

Is it possible to reset toner chips (RFID Tags 13.56 MHz) with this approach?

[Kholaslittlespot]

I'm interested in adding an OLED screen to display data from the tag. I'm pretty new and am unsure how both devices would connect if they share pins. Do I need to re-address pins, or just provide different IC2 addresses? Any help appreciated.

Your code is working but i cannot read the data continuously... If i read the continuously ... Authentication error is occured....

[Lamoboos]

Does that work if the text in the rfid card has auth key?

[bobpiper]

It is telling me directory does not exist Errno 2. If anyone finds a solution pls reply. Thx for your time. (Problem solved, in the tutorial it does not say how to save the python file)

[tenchujonacarbonero]

hello! your video was a great help thank you very much!
How can I connect more than one reader to the raspberry?

[markgil]

What if i install a devian os in my rpi does this tutorial the ssme?

[magiconverse]

Why are the jumper wires loose on the pins? I’m trying to put the pins into the breadboard and they seem too short

[venric]

Hi, it don't work for me with the latest version of OS and Raspberry Pi3 model b. What OS release you used? Thanks

[manuelsanchez-zecl]

is there a way to add an antenna to extend the range of the reader? Preferably a couple of feet
