In what order is it customary to write the identifier bits in EM-marin tags?

Question

RFID

The essence of the question is this: let's say we read 40 significant bits of the identifier from the map. So, how now to bring this set of bits into the usual HEX form? Do the bits go from high to low, or vice versa? (there is no label with a stamped number to check ...)

Let's say ID was considered:
0110 1011 0000 0000 0110 0001 0010 0100 0001 1100 (omitting parity bits, etc.).
If translated in the same order as it was considered, then it turns out from the most significant bit to the least significant:
6B 00 61 24 1C
Will such an ID decoding be correct?
If you believe the description of the protocol here at this link , then it turns out just like that, I did not find other descriptions ...
