Barcode
Every time when I go to do grocery, I will normally bring my kids along. They like to see the varieties of merchandise items on the shelves. The thing that annoying me sometimes is when they start playing with the wall barcode scanner to check the prices of these items. They will compare the price on the tag with the price in the system by using the scanner and now my girl wants a barcode scanner for her self-made grocery store at home.
