Linear & 2D Codes

What is a 2-D  Barcode (Data Matrix)?

  • A two-dimensional, (2-D) machine-readable code capable of a higher data capacity than a standard 1-D linear barcode
  • A public domain code and a recognized international standard (BS ISO16022)
  •  An approved code for use within Aerospace (ATA Spec2000)
  • A code suitable for use in industrial applications

Why Use a 2-D Barcode?

  • Considerable more information can be stored in a smaller area
  • Automatic data acquisition/transfer with high accuracy and reliability
  • Elimination of human transcription errors through the use of automatic data collection

Linear Barcodes

Barcodes in their most familiar format — a series of varying-width parallel bars and spaces — have been with us for over 25 years. These linear, or 1D (one dimensional as opposed to two dimensional bar codes discussed below) symbologies continue to be the most widely used optical recognition technology. Well over 100 encodation schemes or symbologies have been invented over the years, but the most common 1D symbologies are Code 39, pioneered by the defense and automotive industries; the Universal Product Code (U.P.C.), first employed by the supermarket industry in 1973; Codabar, used early on by blood banks, Interleaved 2-of-5 (ITF), and Code 128.
