Barcode Scanners


Modern day shopping is quite faster than before barcode scanners were invented. Being able to whiz through a large grocery store order is something that few people actually pause to think about. Without barcode scanners each price would have to be located and keyed into the cash register manually. This could double or triple your time at the checkout counter of the store.†

Barcode scanners at first were wired into the computer cash registers. Cashiers could only scan items within reach of their scanner since the cables were not extremely long. When barcode scanners and readers became wireless cashiers could just walk around to the item, scan it with their hand scanner and the price would automatically ring up. Some barcode readers and scanners could actually pick up a price a few feet or yards away. The laser technology involved has been fine tuned and developed into something we take for granted while out shopping.†

When placing your items on the register belt for the cashier always try to place them with the barcode facing up or towards the cashier. This will enable the cashier to ring your items up much faster. This especially helps for large or heavy items. Even if you have the large item in your shopping cart if the barcode is visible they can easily scan it from wherever they are standing. This works well for large items like cases of soda, water, or baby diapers that you place under your shopping cart on the shelf.†

UPC codes, or Universal Price Codes, were developed in the 1970ís and these codes along with the barcode scanners are what revolutionized the shopping industry. RCA, IBM, and Sylvania were key companies involved in the barcode scanning industry. Krogerís was actually one of the first grocery store chains to work with developers to test and evaluate the UPCís and the barcode scanners.†

There are different kinds of scanning systems. Some are complex and some are simple. Each built to do a specific job. Some use symbology and some are very basic and operate using a photo sensor. We see barcodes on just about every item. Companies use barcodes to keep track of their equipment, Railways use barcodes on freight cars, and libraries use barcodes to keep track of their books and periodicals. Barcodes are essential to everything we do.†

Barcode readers and scanners are very popular with the airlines too. Since they changed over to electronic ticketing passengers no longer have paper tickets with boarding passes attached. Passengers can either print a copy of their boarding pass from their carrierís website or bring it with them to the airport or if they have internet access on their phone they can bring up the barcode on their phone and the gate agent can actually scan them in and let them board the plane.†

Being able to use cell phones and Smart phones to bring up UPC codes saves more than just time. Being able to use electronic devices saves paper which in turn saves our forests and helps the environment.†
