barcode scanner

Last Monday while waiting for my mom to be done on her Theraphy appointment I walked by to the clothes store near by. And I found some clothes that I like. But I was not able to bring them home. I got so annoyed when I’m about to payed the item. It takes ages! I wish that store could get a barcode scanner to help them. So that they don’t have to type in all the codes on the computer when doing the sale and type the wrong codes and selling things at the wrong price.
