Definition Laser Barcode Reader/Scanner are the most common type of Barcode Readers/Scanners. A laser Barcode Reader/Scanner need not be in contact with a barcode to read it. A standard range laser Barcode Reader/Scanner can read a barcode from about 6 to 24 inches away, and a long range Barcode Reader/Scanner can read one from perhaps 2 to 8 feet away. Certain extra long-range laser Barcode Readers/Scanners are capable of reading a barcode from up to 30 feet away.
