I'm creating a clocking in system for work and I'm considering using a raspberry pi for the card interface. Having never used one before I just want to check if this is possible. I've seen a few things about how to read the cards but I can't find details on how to write the cards.

Are you able to write RFID cards from a raspberry pi and can you point me in the right direction if so?

    search for raspberry pi rfid writer and you'll find there's plenty of products to choose from, and equally plenty of tutorials Feb 25, 2020 at 21:43

    A group of "my" middle school kids did that as a project. See Jaromanda X's advice about searching. Get everything working with a breadboard, then use one of these to make the connections permanent: adafruit.com/product/571 You'll need a suitable case, too.

  • This tutorial looks good: "How to setup a Raspberry Pi RFID RC522 Chip (Level - Beginners) - Gus, PiMyLifeUp 2019oct03 ": pimylifeup.com/raspberry-pi-rfid-rc522.

    thanks all. I'll have a read of that tutorial. I think Ive been confused thinking a reader and writer were different things but looking at these I think it might be the same thing in some circumstances. Feb 26, 2020 at 6:47
  • Ha, yes, I was also confused, when I tried to answer the following question: How to configure PN532 RFID module as a NFC tag ..." (Note: Read the chat record): "raspberrypi.stackexchange.com/questions/108502/…". I knew the PN532 module can read and write RFID card, but I did not know that the module can also PRETEND/FAKE as a NFC/RFID card/tag. In other words, it can do three things, (1) Read, (2) Write, (3) Pretend to be a card/tag.
