Is it possible to read card ID and memory?

[mrNo0b]

I use this library, everything works fine, but I would also like to read data that I write to the cards/tags. Is it even possible with WG? Do I have to buy specific WG RFID reader or everyone can read memory? I don't know much about Wiegand protocol and RFID that why I ask,,,

Hi @mrNo0b

The Wiegand RFID reader will only output the card ID.

To read data written into user area, you need RFID reader like this

Thank you for the info!

I use this:

I also have MFRC522 but the problem is that this board is not exactly "production ready" I will need some case for it and it requires too many wires instead of D0 and D1...😢
