How to get 5 bytes UID ?

[msw1998]

I want to get 5th byte output from MIFARE Classic Card instead of 4 bytes output.
Currently I am getting this UID from arduino code
8B 65 66 B9
but from the raspberry pi code of SimpleMFRC522.py I get this uid in hex
8B 65 66 B9 31

I can't update the raspberry pi code to change the output from 5 byte to 4 byte as it is already in production
Is there anyway I can get the 5th byte from this library?

Block 0 contains the raw data for uid.

How can I print the raw data for the uid?

I did run the dumpinfo and it only gives me 4 bytes as mentioned above
i tried increase uid->size to 5 and increase the bytesToCopy variable to 5 as well
then it outputted the 5th byte as 00

The fifth byte is just a checksum. For instance, in your case:

In [1]: hex(int("8B", 16)^int("65", 16)^int("66", 16)^int("B9", 16))[2:]
Out[1]: '31'
