Fingerprints don't expire

Electronic chip in ID card for Emiratis lasts five years (Zawya.com)
Abu Dhabi: The Emirates Identity Authority (EIDA) has fixed a five-year validity period for Emirati national ID cards because of the five-year life span of the electronic chip in the card, the authority explained yesterday in a statement.

The lifespan of the electronic chip in the national ID card is five years, Eida said.

And there may be biological changes in an individual with ageing which affects biometrics like fingerprinting. “Such changes have to be recorded in the system,” Eida said.
There are all sorts of good reasons to have ID cards expire but, barring severe bodily trauma such as permanent scarring or actually losing digits, changes to fingerprints aren't one of them.

Baby footprints are taken at birth and, given adequate skill and care in recording them, they are reliable over extremely long periods of time. FBI print experts have identified the adult victims of such disasters as fires and airplane crashes by using the footprints of the individuals taken in infancy.

Anybody know why they use baby footprints instead of hand prints?
