A barcode is compiled of machine-readable information, which is commonly used on retail merchandise and other tangible products. Standard barcodes feature a series of printed parallel lines with numbers located just below. Barcodes are read by barcode scanners, which are also known as barcode readers.



A barcode scanner is a computer device used for reading printed barcodes. This type of product is commonly found in retail stores. A small handheld unit that reads, translates and provides information from a product is one type of popular scanners. As you pass through the checkout line, if you notice the checker searching for a tag, he or she is likely looking for the barcode. Among other things, a barcode scanner can interpret an item description and price from just one quick swipe.

Similar to a flatbed scanner, barcode scanners consist of a light source, lens and photo conductor. These come together to translate optical impulses into electrical impulses. The vast majority of all barcode scanners feature decoder circuits, which analyzes the barcode's image date.

There are a variety of barcode scanners on the market, including the handheld model as previously mentioned. Pen scanners are small and look exactly like a writing pen. In order for them to work, you must point the tip at the beginning of the barcode and slide it across until the entire code has been scanned. Stationary scanners are similar to those found strategically placed throughout retail stores. These are usually posted for customers who wish to find out the price of an item without standing in the checkout line, which they can quickly accomplish by holding the barcode underneath the scanner window and, within a few seconds, the product name and price is displayed on a small screen.

Barcode scanners have helped to make the retail world, along with other businesses, work more efficiently and accurately. With computerized data being stored in one main location, a barcode automatically reads the product data and allows customers to get through the checkout line much faster. In addition, barcode scanners are beneficial in helping to keep track of sales, measure accurate sales records and provide an efficient way for stores to reorder a product.

Barcode scanners are available at most office supply stores, specialty business centers and at business liquidation sales. Prices vary depending on the model, performance and warranty that you select. Barcode scanners are a good investment if you need to have an efficient way to distribute, manage or keep track of sales, revenue and reorders. Before choosing a barcode scanner, be sure to realistically assess your business needs, size requirements, a reasonable budget and performance guidelines. For example, will you be using the scanner in a retail setting? Will it be used by cashiers, stationed throughout the store or both? As with any business equipment, always select a reputable dealer and inquire about product warranties. Retain all warranty information, along with the owner's manual, in case of future technical problems. All paperwork should be tucked away in a safe location, which is easily accessible incase it is later needed.
