GS1-128 Barcode Introduction
GS1-128, is a high-density, discrete linear barcode which is employs application standard of GS1 implementation within Code 128 barcode. GS1-128 is also known as EAN-128, UCC-128, USS-128, GS1 128 and GTIN-128. It is able to encode high density data including all 128 ASCII characters and widely used in retail and shipping management systems. GS1-128 is able to handle distinguished information since it utilizes a series of Application Identifiers. For example, AI 00 indicates the Serial Shipping Container Code, 21 indicates the Serial Number, 310y means the data encoded is related to Product Net Weight in Kg etc.
