I love barcode scanners! I really do! I love scanning items at Walmart to see how much they cost. I love the places that let you check out yourself. I love the barcode scanner on my iPhone - I use it to scan items into my grocery list. What is it about barcode scanners? I have always loved computers so I guess it has something to do with that. I also like the little beep you get when the item is scanned. What would we do without them? Enter everything by hand, that's what!!
