Fingerprint scanners are known to record a portion of your finger in order to be accessed. What would happen if you age? Your hands grow and eventually even get wrinkles on your fingers. Would a fingerprint sensor still work?

For Example: A toddler is given an fingerprint scanner of some sort and he inputs his fingerprint. He ages and his hands grow with him. If he is now 7 years old would he still be able to access the fingerprint scanner of some sort he input his fingerprint years ago or would the scanner fail to recognize his finger print

  • Probably not as well... note however that it takes years*/*decades for the fingerprints to deteriorate and in decades you'll most likely change device which means you'll provide new fingerprints which include some of the deterioration. The only places which might have issues are something like military facilities (or similar) where you may have access for decades and in that case I believe they'll probably update the fingerprints in the database every X years for the personnel.

    Sorry, this site is not for asking any question you might have - it is for (dis)proving claims. If you can find references claiming that fingerprints scanners no longer seem to work with age, edit them into your question.
