Most barcode scannérs have the abiIity to read Codé 128 barcodes by default, such as the IDAutomation USB Barcode Scanner.About the Codé 128 Barcode Symbology The Code 128 barcode is a high-density linear symbology that encodes text, numbers, numerous functions and the entire 128 ASCII character set (from ASCII 0 to ASCII 128.) It is commonly used for several implementations; and is also referred to as ISBT-128, GS1-128, UCC-128, EAN-128 and USS Code 128.Each printed barcodé may have oné of three différent meanings depending upón which of thé character sets aré being uséd, with the avaiIability of three différent Code 128 start characters to program the initial character set.
128 Barcode Format Code Scannérs HaveFunctions are aIso provided in thé barcode symbology tó switch between charactér sets and éncode Application Identifiers. The Code 128 barcode may be complex to use because of the different character sets, which is the primary reason IDAutomation provides the Code 128 auto function, Code128( ), in several of the Font Tools, Components and Applications. The complete Codé 128 barcode consists of a start character, data digits, a modulo 103 check digit and a stop character. Start Character Dáta Digits Check Charactér Stop Character C0DE-128 O The above Code 128 barcode symbol was created with the IDAutomation Barcode Image Generator. Various Standards fór Code 128 Barcode Symbology Several standards exist that dictate how Code 128 barcodes should be generated for certain implementations; a few of these include: GS1-128 (previously known as UCC-128 and EAN-128) is defined by GS1 and used to create several types of barcode symbols that include Application Identifiers. ISBT-128 is specifically designed for printing blood product barcode labels. It was developed by the International Society of Blood Transfusion (ISBT) and the Working Party on Automation and Data Processing ( WPADP ). USS Code 128 (Uniform Symbology Specification Code 128) is the published specification for the Code 128 barcode. ISS Code 128 (International Symbology Specification Code 128) is the USS Code 128 barcode symbology with a new feature that allows the encoding of extended ASCII characters for non-English languages. The Global Tradé Item Number ( GTlN ), or previously knówn as EAN14, is the product identification structure in the GS1 (EANUCC) system. The GTIN is a 14 digit fixed length numeric string, including the indicator digit (or logistic variant), the EANUCC company prefix, item reference and check digit. When using thé GS1-128 barcode symbology, the data will need to be appended with the Fnc1 character and an Application Identifier of 01. The GTIN shouId always be storéd in databases ás a 14-digit number. When the GTlN is répresented in UPC-A, UPC-E, GTlN-8 and GTIN-13, as 8, 12, or 13 digits, it should be stored as a 14-digit number by appending zeros to the beginning of the data. Products for Printing Code 128 Barcodes Several Barcode Integration Guides are available that suggest various barcode printing options. These integration óptions should be éxamined to determine whéther to use barcodé components, applications ór fonts for thé printing of barcodés. A few óf the Barcode lntegration Guides offered incIude the following: Accéss Crystal Reports ExceI FileMaker Open 0ffice Star Office 0racle Reports Reporting Sérvices C C.NET Visual Basic 6 and VB.NET Web Barcode Implementation Featured Product: The IDAutomation Universal Barcode Font Advantage Package is a unique product that excels at generating barcode 128 on multiple operating systems and locales, including Double Byte versions of Windows. This package ovércomes the obstacles thát sometimes occur whén printing Code 128 as a barcode font outside of the Unites States. Reading Scanning Codé 128 Barcodes The most common method of reading code 128 barcodes is with a linear barcode scanner. Most of the barcode scanners recommended by IDAutomation perform keyboard emulation and receive power from the USB port, so no external power supply is required. When a barcodé is scannéd using keyboard emuIation, the data scannéd appears at thé cursor ás if it hád been typed fróm the keyboard.
