Bluetooth Barcode Scanner

I hate it when it's payday and everyone is at the supermarket . That would only mean one thing..long lines! With the volume of the people shopping compared to the number of cashiers open to ring your groceries, a long line is really expected. But two weeks ago, I was amazed to see the new bluetooth barcode scanner at the cashier. Wow!It surely made everything a lot faster than before. A lot of customers were happy that they upgraded this tool from their old one. It made things easier both for the cashier and the customer. I hope some other stores would follow too. No one wants long lines when paying, right?
