@Pilgrimsmaster, I found a location that seems to be pretty stable as shown here. Also, I can confirm it is a 4-bit key. I am not sure if it is a Gen2, but I could get a read using TagInfo.
@Equipter- I started running hf mf autopwn, but it’s been running for about 10 minutes. About how long should I expect this to run in your estimation? Also, are these error codes being thrown expected?
Thank you for your help!
