An Introduction to Barcodes
Overview
Barcodes transform numeric or textual information into a machine-readable format, significantly reducing costs in warehouse management and inventory control. There are two primary types of barcodes: Linear and Two-Dimensional (2D).
Types of Barcodes
Linear Barcodes
Linear barcodes encode data in a one-dimensional, horizontal format, typically storing between four and forty characters. While most linear barcodes only encode numbers, exceptions like Code 39 and Code 128 can include alphanumeric characters. The most widely adopted linear barcode is the EAN code, used globally for retail article numbers, except in the USA, which uses the UPC code. Variations of EAN include:
- EAN with Addon: A smaller barcode, or Addon, accompanies the main barcode to encode additional information, such as pricing.
- Five-digit Addon: Used for ISBN (International Standard Book Number).
- Two-digit Addon: Used for ISSN (International Standard Serial Number).
Other notable linear barcodes include:
- Code 39: Common in the pharmaceutical industry.
- Code 128: Used in warehouse management and retail.
- Code Two-of-Five: Utilized for warehouse management and inventory.
Two-Dimensional Barcodes
2D barcodes can encode much more data, up to three thousand characters, thanks to their format. They often include numbers, letters, and special characters. Popular 2D barcodes include:
- PDF417
- DataMatrix
These are widely used in manufacturing, package tracking, and situations requiring extensive data encoding.
Barcode Checksums
Barcodes incorporate checksum or check digit mechanisms to ensure accurate reading and scanning. A checksum is derived from the encoded data and appended to the barcode. Scanners verify this checksum during the reading process to confirm data integrity. While simple check digit systems detect basic errors like missing characters, more advanced systems in 2D barcodes can also repair damage to the code.
Applications of Barcodes
Barcodes are extensively used across various industries. Initially popular in retail to encode article numbers, manufacturer details, and pricing, their usage has expanded to include:
- Transport Industry: For address and tracking information.
- Personal Identification: 2D barcodes are increasingly used in ID cards and driver’s licenses.
- Electronics: Tagging of electronic components like computer chips.
Barcodes have become integral tools in improving efficiency and accuracy across many business operations.
