Use ACR122U as RFID reader #27

Closed raymonvdm closed 6 years ago

raymonvdm commented 6 years ago

I am trying to get an ACR 122U working as RFID cardreader. The reader is seen on the USB port, but it looks like it is not reporting as HID input device

Is it still possible to use this reader (since i had it laying arround)

MiczFlor commented 6 years ago

(I leave this issue open, because I get similar questions quite often)

I can not give any advice how to use this code with this model, because I don't have it here to check if it works :). If you solve it or anybody else has ideas and pointers, feel free to post them in this issue thread.

USB RFID readers usually are set up in a way that they act "like a keyboard". The Chip ID is pushed to the RPi as if you were typing it in a keyboard and pressed "enter". This input is what the python daemon is waiting for and then it pipes the result into the bash script.

raymonvdm commented 6 years ago

I found a work arround but it is not usable without an X session (display connected) so i gave up on it.

Maybe you can uses this code for a solution? In the meantime i ordered some MFRC522 readers just to keep the project going :-)

MiczFlor commented 6 years ago

Hi @raymonvdm , I'll close the issue, because I can't keep up with hardware specific issues and edge cases. Hope you found a solution and got it going.
