in Propeller 2
I once wrote a short program to determine if a card was rw just r on a propeller 1 many years ago. I want to do the same know but for the life of me I can't remember how I did it. Does anyone have an idea?

It would be cool to generate the 13.56 Jigowatts aham, excuse me, the 13.56 MHz carrier using the streamer to drive a coil and then detect the "dips" in the amplitude that the rf chip produes with the goerzel mode - it should be somehow doable
This P1 code looks like it works:

Or, or you using the Parallax 125 Khz UART RFID Reader/Writer ?
Guess that would be easier...
See some people were using an Arduino with it for some reason...

I wrote a driver for the mfrc522 here: https://obex.parallax.com/obex/mfrc522/
