Hello! :smile:

I am trying to do a similar thing with the ID-12 RFID reader. I would like to return the ID number of a tag to the cloud when the reader is presented with a tag. I have tried using this example, but i do not know what changes to make? (I am indeed very new do this)

Here is the layout of the ID-12 pins.

Cheers guys thanks !
