I am very new to all this so sorry for my extreme ignorance. I purchased the ring with a proxmark3 with the goal of duplicating cards for work. This worked fine for writing to a test 5577 card but have been unable to read or write to the 5577 in the ring. I know it is supposed to be programmed by default but clearly I have broken or erased it by accident.
Unfortunately still silence. Is it possible that such a thing could occur in shipping/handling? If it is actually dead I’ll get another and use my card for now
Yes, I have done a clone of a Keri card out of curiosity. No issue writing to the included ID-5577 card. I too thought that might be the issue but tuning shows no problem and it easily detects other cards.
Just checked mine and it goes from 25/26 to 23/24 depending on orientation. Having the ring opening at 90’ to the antenna causes the biggest voltage drop.
