This reminds me of an article I read about street vendors in Southeast Asia offering ID photos, which was a bustling business, since most people at the time had no photo ID whatsoever.

Something like this: https://www.alternativephotography.com/wet-contact-printing-negatives/ https://www.alternativephotography.com/wet-contact-printing-... Aside from the idea that most people had no ID, the more interesting tidbit was that these vendors were known to scam people by giving them photographs of other people! Apparently, the whole ID/photograph thing was so novel that many customers didn't notice the substitution.
