RFID Kit RC522

I initially had problems with the boards becoming unresponsive. It turns out it's not the board but the self-test call in the Arduino library!

I got this as a little side project to mess around with on my Raspberry Pi. I wasn't too sure how to install this properly but upon purchase I got an email with all instructions and how to install. Within about 15 minutes, this includes soldering time as well, and installation onto the Pi I was running and managing getting the RFID tag recognised and printing the id etc. The fob and the card that come with it worked perfectly as well. This actually seems perfect both for a production and a side-hobby environment!

Took me a few hours to work out how to read and write data to tags using this and a raspberry pi but I got there in the end and it works really well. However, I was hopeful that it could be used to clone a key fob I already have but the fob and card included don't have changeable UIDs. Most NFC tags have locked UIDs like this I was just hopeful given the nature the device that that wouldn't be the case. Basically it's not a problem with the product but I wanted to make it known to anyone who might be in my shoes

Bought as a gift, but they arrived promptly

Following the link included with the chips took me to all of the relevant documentation for wiring it up to my raspberry pi, which was easy to read and get hooked up. I didn't use their suggested library for interacting with the chip, googling the board name and then python library brought up a vast selection of code to help you get started with this board. Within about 30 minutes I was scanning all of my student ID and reading it through a simple python script on my raspberry pi. Very happy! Just be prepared to do a bit of soldering (it's really easy) Really cool that it comes with programmable chips and cards to work with too, so that you can start prototyping and getting to grips with the chip without damaging any of your actual RFID cards.

It seems ages ago now, but it very good has I recall.

I used these with an alarm system, worked great.

Was easy to setup, plenty of tutorials online. Unfortunately I couldnt use it, it doesnt work for rfid chips in pets, or those tags that rfid that surefeed and other petcare suppliers use. It requires close contact to trigger and there doesnt appear to be any way to use a wire antenna so that it can read tags passing through a doorway. I couldnt get it to read at the advertised 3cm range.

Individually packed in anti-statick bags. Includes QR that directs to manufacturers website with how to e-books. Good quality product overall.

Funziona perfettamente.

Doosje enigszins verfrommeld bij aankomst maar alles er in is prima. Eén set inmiddels in dienst

Gör vad de ska har börjat testa dem och allt till belåtenhet

Wurde schnell geliefert und entspricht der Abbildung. Das Modul unterstützt SPI (vorkonfiguriert), UART und I2C. Das Interface muss über KonfigurationsPins ausgewählt werden. Allerdings gibt es bei diesen Modul keine Pull Up/down dafür. Entsprechend Datenblatt müsste man für den UART Pin EA von high auf Low ziehen. Hier würde es aber bedeuten, eine Leiterbahn zu durch trennen und eine Drahtbrücke nach GND zu ziehen. Ich verwende das Modul über SPI an einem Raspberry Pi Zero mit Python für eine Kinder Musikbox. Die Pythonbibliothek, welche ich zuerst gefunden habe für das Modul, war leider nicht mehr ganz aktuell und passte nicht zur SPI Bibliothek. Da hatte sich was bei den Parametern für SPI read und Write geändert. Aber dafür kann das Modul ja nichts.
