When creating a single barcode, IDAutomation recommends using the Online Barcode Font Encoder. Therefore, references to the character sets should not be necessary. This site demonstrates how the symbols are created from the characters found in the different character sets.įor easy application integration, IDAutomation provides several Font Encoders that are free to use with IDAutomation barcode fonts. The character set for this symbology is best described by viewing the UPC/EAN Barcode Font Specifications. This scanner dependably reads the IDAutomation UPC/EAN Font when printed at any size allowed by GS1, which is from 12 to 32 points. Most barcode scanners have the ability to read UPC and EAN barcodes by default, such as the hand-held IDAutomation USB Barcode Scanner with DataBar. When a barcode is scanned using keyboard emulation, the scanned data appears at the cursor as if it had been entered from the keyboard. Most barcode scanners recommended by IDAutomation perform keyboard emulation and receive power from the USB port, so that no external power supply is required. The most common method of reading barcodes is with a barcode scanner. For a thorough evaluation of these products, visit the Barcoding for Beginners FAQ & Tutorial. IDAutomation offers many other barcode generation products. When creating a single barcode, the online font encoder may be easily used with the UPC/EAN Barcode Font.

The font meets ANSI, ISO and IEC 2000 specifications (ISO 15420:2000) and is supplied with several barcode font encoders, plug-ins and source code samples for easy application integration. The IDAutomation UPC/EAN Font Advantage Package is a single font used to create all UPC-A, UPC-E, EAN-8, EAN-13, JAN, ISBN and Bookland barcodes.

A few of the Barcode Integration Guides offered include the following: These integration options should be examined to determine whether to use barcode components, applications or fonts for the printing of barcodes. Several Barcode Integration Guides are available that suggest one or more barcode printing options.

Visual Basic source code to the compression algorithm may be obtained by examining the UPCe7To11 function in the IDAutomation Visual Basic Source Code, which is used to automate printing for the IDAutomation UPC Barcode Font. ** The UPC-E number of 02349036 displayed in the barcode equals the 00023400000900 UPC-A number after it is expanded by the UPCE suppression rules.

If the full 14-digit GTIN is needed after reading the symbol, it may be generated with a MOD10 calculation.

The last digit of the GTIN-14 is a MOD 10 check digit and is not encoded in the DataBar symbology. * GS1 DataBar ( previously known as RSS) barcode encodes 13 digits with the required AI of 01 and a DataBar check digit. The portion of the GTIN displayed in green is what the associated symbol cannot encode. The various types of UPC and EAN barcodes with their GTIN capability.

DataBar Expanded should be used when it is necessary to encode additional information such as weight, expiration dates and country of origin or serial numbers.įig: 1. When encoding complete GTIN-14 numbers, GS1 DataBar should be used. For example, a UPC-A barcode of 123456789012 would be represented as 00123456789012 in the database of a GTIN compliant system. To be fully GTIN compliant, all UPC and EAN numbers should be stored in databases as 14-digit numbers and filled in with zeros for the spaces to the left as shown in Fig: 1.

Less chance of scan errors than UPC and EAN symbols.

Better sell by and expiration date management.

Traceability and product recall capabilities.

Smaller size and usually quicker scanning.

The benefits of using DataBar instead of UPC and EAN include: POS systems have been required by GS1 to read DataBar symbols since 2010. GS1 DataBar is a barcode type that works just like UPC and EAN barcodes, with enhanced capability. UPC, UCC, EAN, JAN, GTIN-8, GTIN-12 and GTIN-13, ISBN and Bookland barcodes are all created from the same symbology type, commonly known as the UPC/EAN barcode. The UPC and EAN barcodes have been in use since the 1970s to encode Global Trade Item Numbers ( GTIN), which uniquely identify a product for retail checkout or tracking purposes.
