Supported barcode symbologies

All barcode types supported by the SDK and their common applications

1D barcodes

1D barcodes, or linear barcodes, are the original type of barcode. They are widely used across various industries for simple, efficient data encoding. These barcodes consist of parallel lines of varying widths and spacing, which represent numeric or alphanumeric information. This data can then be scanned rapidly and reliably with barcode readers. 1D barcodes are particularly common in retail, inventory management, and logistics, where they serve to streamline operations and enhance data accuracy.

EAN

image

The European Article Number (EAN) is a standard barcode symbology used for product identification in retail and supply chain management worldwide. EAN barcodes encode Global Trade Item Numbers (GTINs), which uniquely identify products. They are assigned and managed by GS1.

  • EAN-13: 13-digit barcode for individual product identification, used globally.
  • EAN-8: Compact 8-digit barcode for small product packaging, suitable for retail and distribution.
  • EAN-2: 2-digit supplemental barcode used with EAN-13, typically for issue numbers on periodicals.
  • EAN-5: 5-digit supplemental barcode used with EAN-13 for price, weight, or variant information.
  • ISBN: The International Standard Book Number (ISBN) barcode is a specialized form of the EAN-13 used exclusively for books.

UPC

UPC-A Example

The Universal Product Code (UPC) is a barcode symbology widely used in North America for retail and distribution purposes. UPC barcodes encode Global Trade Item Numbers (GTINs) to uniquely identify products. This facilitates efficient supply chain management.

  • UPC-A: 12-digit barcode encoding the GTIN, widely used in retail and distribution in North America.
  • UPC-E: Compressed version of UPC-A barcode, designed for smaller items where a full 12-digit barcode would be too large.
