Online stores with barcode scanner

My friend Kim and her hubby are going to start up a new online store. In fact it has been launch unofficially. I check out the online store and they only have 3 items at the moment. They will be adding more items when it is available. At the moment they are not using any barcode system. I think they their business grow, they will probably need to get one of the barcode scanner like the ls2208. I have seen such scanner in use at some of the big stores here. It is pretty useful and handy for the staff to use.
