Paying at the check out counter is now faster and easier, thanks to the barcode scanner. This piece of technology has been very helpful to both the shopper and the seller. The shopper no longer has to stand in line very long while the cashier goes through each item he/she bought. With the scanner, check out is done in a couple of minutes.
This electronic device used for reading printed barcodes on packages of goods we buy was first developed to help get an accurate and faster inventory of grocery items on the shelves. This enabled the seller to know with accuracy the stocks on-hand so that they can immediately order or replenish their merchandise. Today, sellers ranging from small convenience stores to large shopping centers use barcode scanners.
