It's not as matches/doesn't match as it looks like
Taking a print is not perfect, even in perfect conditions. From a print in an object, not good at all.
And a lot of people have similar prints. You can't have one print you recovered from some place and find a perfect match with 100% confidence in a database (your target may not even be on the database)
Having a known identity and matching a provided sample to that DB is much better, as is having a smaller DB (for example, entering a gym)
So, yes, you can have a computer finding candidates but then you can have a human to match it more carefully (that's what the Spanish did apparently)
