BAR CODES

BAR CODES

1. Adavantages

   • Stores specific data
   • Cheap to operate
   • Finds the prices of a product faster than doing in manually

2. Disadvantage

   • Can only be read by a barcode scanner
   • Can only be scanned manually at a time.
   • Can be easily damaged

3. The checkouts at stores have barcode scanners when you buy items. This information on the barcode is scanned in the database that shows the prices

4. Self- service checkouts work because all information about the items doesn't need to be entered again since they're already on the store database, so it doesn't need to be scanned again
