RFID reader working properly ??

[mtacki]

Hi all,

I followed the steps above with the exact same hardware...
Unfortunately, my RFID-Reader doesn't seem to work properly.
It's making it's "BEEP"-sound on power-on - but there's no beep when I'm holding a NFC Card next to it... and YES - they are the nfs cards that came with the reader and should therefore be the compatible types.

I could not find any setup steps regarding the reader during the tutorial !?

Shouldn't there be any drivers installed for the reader ??

Thanks and many greets !!

Hi @mtacki
I wish I could help you, but I can't help you much. The USB card readers that I came across all work like this:

• Plug it in: the PC will recognize it as a keyboard
• Swipe a card / key fob: the USB reader will act like a keyboard and "type in the number and press enter"

Therefore: swiping a RFID chip in front of a USB reader will always "enter the number" no matter where you are. If you have the command line open or a text editor, it will literally type the numbers and start a new line.

The ones I know all beep when you swipe. But that might differ from model to model. And I know that not all cards work on all readers. There are differences.

However, as I said, I can't help you. There is the one in a million chance your reader does not work. That might be the case if the wires are broken.

What I do know for sure: the Raspberry Pi does not need any drivers to work with a USB reader.

I hope this helps. All the best, micz

Thank you so much for your answer !!
Since my reader doesn't seem to work properly, I contacted the shop and asked for a refund / exchange... curious how it goes !
Have a nice week !

Hi @mtacki
good luck with the project. As I said, I can not say if the USB reader is faulty or not. The readers which you attach to Arduino devices for example make no sound at all. So I told you all I know, good luck.
