AZDelivery RFID Kit - MFRC522 Compatibel with RC522 RF IC Card Reader Sensor Module, RFID Chip Key Ring and S50 Card 13.56MHz I2C IIC SPI, Compatible with Arduino and Raspberry Pi including E-Book!

I used these with an alarm system, worked great.

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

My order arrived ahead of the earliest delivery date in perfect condition. The items were exactly as wanted - BUT. The description includes a E-book, presumably with the instructions I need. For that, the package contained a small card with pictures of E-books and a website address. Unfortunately, the card was in German! Not really a problem as the website address was obvious. However, on visiting the website I found that it was also in German and could not find any way to view it in English. Struggling, I found that an appropriate E-book appears to be available. This is free, but to get it requires entering an online form in German - haven't managed to do that yet :-(

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!

Works fine, connect and load the libraries and away you go...

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.

I bought a cheap one of these from Ebay I think it was. However, it was corrupt, never worked, that's the chance you take when buying cheap.So I paid a little more (well worth the money) and no issues at all.. I have one for the nfc mp3 player I'm building and another for programming nfc cards, leaving 1 spare.No instructions included, but qr code takes you to a site where instructions for this and other products are available. Instructions were clear and example code given.I would definitely recommend this item for your projects and thankyou to the seller..

I just honestly couldn't get it to work
