Travel thoughts: Incoherent Seats and Pattern Matching on an un-developable surface

I thought this was funny or I am becoming too much of a nerd.

As I was boarding a plane recently, the gate attendant took my boarding pass and patched it through some reader. The LCD screen buzzed and blinked with the mention "Incoherent Seat". So a seat number is now a projection, what's up with that ? I thought.

I was also going some pretty thorough fingerprinting exercise in the same journey and was thinking: What type of software does pattern matching for patterns that are inscribed on a non-solid and non-cylindrical (un-developable) surface ? what are the chances this projection is different everytime you take a new fingerprint ? I'd like to know.
