Fingerprint

From Wikiversity

There are many operations with a scanner. It could be great to see a car that you open only by a hand and it stays fully secured.

Before the conception was to pay just with a finger. It was generated on when an EU community was preparing to enter a fingerprint system to a special agents in their department. my friend asked me from where they will have a copy of the same fingerprint? and idea was going further

step one: department store collects it when asks an information for a customers database. or probably it is in the banking database, where you store your funds. and all pay terminals have an admission to operate with your identification. but we need very very strong computers.

step two: department store has integrated with a government database, but uses a commercial, previously allowed data only. also was spoken about a subway security, for example i saw a subway where a door opens by a finger pushing, as i understood it was made to lower electricity consumption. But if you have it with a fingerprint scanning, also have a photocameras to see a passenger behaviors, it is very nice to locate a terrorist.
