What is a bar code used for?
Bar codes are used to identify a product, item, device, etc. From there we use the information that is held on a computer server and is associated with that thing for:
- keeping track of the large number of items in a store
- tracking of item movement, including rental cars, airline luggage, nuclear waste, mail and parcels.
- individual bees for researchers to track the insects' mating habits.
- tickets which allows the holder to enter sports arenas, cinemas, theatres, fairgrounds, transportation etc.
- for advertisement, information services etc. (for mobile tagging)
- and can also be used for the game thing where you get creatures when you scan a barcode, those things are cool!
