check digit - What is the algorithm of generating the code on 100 USD banknote? -

i designing primary key storing product. around find insight how design id using auto increment boring. 1 know code 'kb46279860i' on below banknote meaning?

100 usd picture

i think code not using auto-increment algorithm check digit,etc.

could 1 give me hints , thanks!!

if you're not planning on showing user id auto-increment save processing time handled database directly.

if planning on showing id user without showing 1 in database, consider using hashids, or guid or generating own unique random value check digit. can utilize luhn or damm's algorithm check digit.
