Irresistible Barcoding

Bar coding is the most common ID technology providing instant, error-free information that can be used to accurately verify routine business transactions and increase productivity. In fact every type of industry is using barcodes to replace keyboard data input. Studies have shown that a proficient data entry clerk will make one error for every 300 characters which are manually entered. 1/300 is way too high as an error rate. The error rate using bar codes is almost negligible. And if we use bar code symbologies with check digit support, it can be error-free!

Bar coding is similar to Morse Code. Instead of using dots and dashes, bar coding uses wide and narrow bars and spaces to encode information.

Nowadays we see bar codes marked on grocery items everywhere. Meanwhile we all have experienced the benefit of being checked-out in a fraction of the time that it took when a supermarket clerk had to manually enter an SKU (Stock Keeping Unit) number for each item. With this technology, not only does the customer get benefit, but the store managers can easily maintain an accurate, efficient stocktake since it's connected directly to the store inventory data base. While grocery and retail uses of bar codes are the most commonly recognized applications, they account for only one third of all installations. Industrial, governmental, and health-care installations have historically accounted for the rest. Many possibilities exist and, with the advancement of ID technology, previously inconceivable applications begin to emerge.

Usually most of the inventory systems don't have to be modified to support bar coding solution. USB, RS232, Keyboard wedge products are available for most terminals, POS systems and PCs. When a bar code is scanned, the barcode data appears on the computer screen. This is the basic component of a bar code system that should be considered in the first place.
