The fingerprint access systems schools and other organisations use is nothing like conventional fingerprinting, where an image is available for copying or checking.
The systems only take a digital image of a person's fingerprint. This is stored as some sort of numerical code but can't be transmitted or transferred from the system.
There are lots of more learned and technical explanations online which would make my brain explode. But I have no problem with these systems, which actually cut down the amount of bullying in schools by doing away with the need for children to have cash or cards.
What's one health habit you've started that's actually made a difference?
