UCC/EAN-128 is not intended to be used for data to be scanned at the point of sales in retail outlets. UCC 128 facilitates the encoding of the full 128 ASCII character set. The use of three different character sets (A, B and C), one of the most compact linear barcode symbologies. Character set C enables numeric data to be represented in a double density mode. Here, two digits are represented by only one symbol character saving valuable space. This symbology uses two independent self-checking features which improves printing and scanning reliability.

Ultraviolet light

Ultraviolet is the invisible range of light spectrum from 200-395nm. UV light is further categorized as UVA, UVB, and UVC. The specific wavelength range for UVC is 200-280nm. This range of light is commonly used for disinfection applications.

USS (Uniform Symbol Specification)

The current series of symbology specifications published by AIM; includes USS-I 2/5, USS-39, USS-93, USS-Codabar and USS-128.                                                                    

Valid characters

Lists the available characters or character sets which can be encoded with the symbology.                                                                                                                                       

Verification / Barcode

The technical process by which a Bar Code symbol is evaluated to determine whether it meets the specification for the specified symbol.                                                                 

Verifier / Barcode

A device that measures a symbol’s bars, spaces, quiet zones, and optical characteristics to determine whether it meets the requirements of a specific symbol. A verifier should not be confused with a bar code reader.
