Linear or 1D barcodes, like the UPC code commonly found on consumer goods, use a series of variable-width lines and spaces to encode data — what most people probably think of when they hear “barcode.” Linear barcodes hold just a few dozen characters, and generally get physically longer as more data is added. Because of this, users typically limit their barcodes to 8-15 characters
Barcode scanners read 1D barcodes horizontally. 1D laser barcode scanners are the most commonly used scanners, and typically come in a “gun” model. These scanners do not need to be in direct contact with the 1D barcode to work properly, but typically need to be within a range of 4 to 24 inches to scan.
1D barcodes are dependent on database connectivity to be meaningful. If you scan a UPC code, for instance, the characters in the barcode have to relate to an item in a pricing database to be useful. These barcode systems are a necessity for large retailers, and can help increase inventory accuracy and save time.
