The point of sale (POS) system is very important locations in every business. It's inefficient for employees to manually enter every Universal Product Code (UPC). Barcode scanners can simplify the entire process and save time during checkouts. These devices read barcodes and enter the product information to your registers.
There are two main types of barcode scanner technologies being employed today: Imager Barcode Scanners and Laser Barcode Scanners. Depending on what you are scanning and how the barcode was printed, choosing the right type of scanner will determine how quickly and easily you can scan.
Imager Barcode Scanner
Linear imager barcode is a Barcode Scanner that really functions more like a digital camera than a laser scanner, and is capable of reading two-dimensional symbols. Linear imager barcode combines the functionality of a bar code scanner, digital camera and document scanner in a single, cost-effective device. Two dimensional barcodes come in a variety of styles. All imagers can still read the one-dimensional codes, but usually without the greater range capability of a laser scanner. There is a significant price difference between imagers and laser scanners but if you need to read anything beyond basic 1D barcodes or have issues with the performance of your current scanners an imager will provide more aggressive and capable reading. Linear imager barcode scanners are better for reading damaged or poorly printed barcodes as well as barcodes under plastic film or covering. Linear imager barcode scanners are ideal for a variety of applications including retail, shipping, receiving, and inventory
Laser Barcode Scanner
Laser scanners provide excellent scanning accuracy and productivity. This allows achieving high productivity in high-throughput areas of business. Laser scanners are capable of decoding barcodes over wide ranges. They can read a barcode from about 6 to 24 inches away; a long range Scanner can read one from about 2 to 8 feet away. As laser scanning technology has been refined, scanners are less expensive than comparable digital imagers. Although laser scanners are incapable of reading 2D barcodes, they are capable of reading 2D-like symbols, PDF417. Laser scanners offer a number of advantages for a multitude of applications and should be considered the technology of choice for: decoding UPC/EAN and other 1D barcodes used in retail, applications that require motion tolerance, self-service shopping.
