I have this Mifare 14 byte UID: "04502E22D45380" than i need to have converted to a 5 byte hex: "63AE03D0AA".
I have tried all kinds of conversions on the web and suggestions and haven't been able to convert it:
Tried to take each nibble from unkown type and Reverse the bits of each nibble (least significant bit becomes most significant bit, second bit becomes second last bit).
Didn't give a useful result.
Tried to take 0450 (0x4 50) away and tried the same, and many hex to binary, to hex... with the the Unique Serial Number:
But I'm running out of ideas. The supplier of the RFID scanner of the unknown number couldn't help either. They said:
Thats difficult i'm afraid. It might have been a 4byte vs 7byte ID thing, but when i assume that we use the 4 and customer the 7byte ID and i XOR this. I don't get the expected result.
So I thought perhaps some of you could help.
this is my try please check the print result if ok ?
here i used
binasciilibrary you can read more on it's documentation here binascii.htmlnot the part of answer but to discuss on result :
after trying to find a potential mistack i try to run all the possible combination to extract hexadecimail out of the 14 digit UID
below i add the all print result please taake a look at it :
