I can't seem to figure out how to set the serial number or get it to generate one. As such I assume it won't work very well if I have more than one of these cards. I'm using a J3R180 card, and as long as I manage gpg and pcscd fighting, I can get this output:

gpg --card-status
Reader ...........: 04E6:5116:53312211227478:0
Application ID ...: D276000124010304AFAF000000000000
Application type .: OpenPGP
Version ..........: 3.4
Manufacturer .....: unknown
Serial number ....: 00000000

I searched the repo but could not find references to card serial number other than in some test scripts. Is this something set with install parameters? custom APDUs? Theoretically generated from some unique on-card value?

I do see that gpg thinks the AID is D276000124010304AFAF000000000000 which ends in a lot of zeroes - do I customize the app AID to set the serial?

I am installing with gp --load ~/Downloads/SmartPGP-v1.22.2-jc304-rsa_up_to_4096.cap
