Yesterday, my husband and I went to the supermarket to buy some groceries. We went there around 8 in the evening and since it is Friday, there were a lot of shoppers and it really took a long time for us to get to the Cashier. Thanks to the barcode scanners that make it a little bit faster to scan and pay for the things we bought. If there were no barcode scanners and payments are done manually, I am sure we would still be in the supermarket until now. This just made me realize that if I have my own supermarket, which will be up very soon, I should invest on reliable barcode scanners to make sure payment processing is done faster and more convenient.
