It's not a software bug. People did this sort of thing before fingerprints. It used to be fairly common for immigrants and refugees to not know their birthday.

It's not a software bug. People did this sort of thing before fingerprints. It used to be fairly common for immigrants and refugees to not know their birthday. The beurocracy was often unable to cope with that idea, as they wanted to use name and date of birth as the unique identifier. A lot of people just made something up to make immigration happy, which then resulted in problems down the line as they didn't recall what they made up.
- hkai 6y agoIndeed! As a software developer in Hong Kong, I learned that the "month of birth" and "day of birth" are optional fields - some people who fled from Communist China to Hong Kong only knew their birth year, and the ID card just shows something like "1946" instead of a full date.
