This probably means that either the card you’re trying to copy to isn’t a gen1a, which you can check with hf search or hf mf info
Or, you aren’t getting a good coupling between the PM3 and the card. Magic cards are particularly picky, try moving the card around on the PM3 and retrying the command. Personally I find I get the best results with gen1 cards about half-on/half-off the PM3
Thanks alot for the response.
I have verified the coupling with hf tune, i am getting a good 7V connection.
Also hf mf info verifies its a gen1 card.
But i was trying to clone between gen1 magic cards to clone each other, not using any original hotel keys, it may be the reason why i cant clone, not sure
