You are likely familiar with barcode scanners used by grocery stores and department stores. These small devices generally enable the sales clerk to quickly identify the price of an item, calculate total, and expedite checkout. However, barcodes are also used for many other purposes. Because barcodes make recording and retrieving data simple, many employers and corporations have begun using barcodes or UPC numbers to keep track of inventory. Barcodes include a range of numbers, bars, and lines. Furthermore, each code is unique. This way, when a barcode is scanned, information about a single product is retrieved. There are many ways to retrieve information from a barcode. These consist of barcode wands, flat scanners, and trigger scanners. Another way to read UPC numbers involves a USB barcode scanner.
USB ports are located on computer desktops, laptops, and select cellular phone models. Because USB ports connect directly to computers, if an item’s barcode is scanned using a USB barcode scanner, the information can be instantaneously transmitted to a computer database or program. Programs might include Access, Excel, or Word documents.
Although USB barcode scanners are commonly used by organizations or businesses as a way of managing inventory or merchandise stock, these can also be used by individuals looking for a simpler means of staying organized. Because barcodes are easy to reproduce using a computer or laptop, small business owners and individuals can create their own barcodes, record information, and place the barcode number on items. If you need to retrieve or record new information, simply connect the USB barcode scanner to the computer port, scan the barcode, and read the data.
USB barcode scanners do not require batteries. Rather, all power is received directly from the computer port. Furthermore, scanners are able to accurately read data and provide a good visual image.
