Re: [Discover TAG]

you have got everything! what else for discover?! you have a reader, what kind of tag is it, picture? any imprint on tag?

Clock:64, Invert:0, Bits Found:625
ASK/Manchester - Clock: 64 - Decoded bitstream:

clear 4 data blocks repeating pattern in the binary string. Sorry even 2 repeat data blocks.

PS: now i understand why you mean with "discover": An EM tag copy to T55x7 with manipulated UID... 1rst question comes to mind: How to program this coded UID? 2nd Question Should we know that ... No, maybe no need...
