About Barcodes

What is a barcode?

A barcode is a method of representing data in a visual, machine-readable form – you can think of it like a different language. It consists of a series of parallel lines or geometric patterns of varying widths and spacings. Barcodes are widely used for automatic identification and tracking of products, assets, and information in various industries.

There are different types of barcodes – linear (also called 1D Barcodes) and matrix (also called 2D barcodes). The primary difference lies in the structure and encoding capacity. 1D barcodes use lines and spaces to represent data in a linear fashion, while 2D barcodes use a matrix of squares or dots, allowing for more data to be stored in a two-dimensional space. The choice between 1D and 2D barcodes depends on factors such as the amount of data to be encoded and the specific requirements of the application or industry.

The most common barcodes are called 3 of 9, 128, and UPC. These are just different styles of encoding information into those lines and spaces.

Linear Barcodes (1D Barcodes): 1D barcodes, also known as linear barcodes, are the traditional and most common type of barcodes. They consist of a series of parallel lines and spaces of varying widths that encode data. The information is typically read left to right, and the thickness and spacing of the lines represent different characters. Examples of 1D barcodes include UPC (Universal Product Code), Code 39, Code 128, EAN-13, and ITF-14. These barcodes are widely used for product identification and inventory management in industries such as retail, logistics, and manufacturing.

Matrix Barcodes (2D Barcodes): 2D barcodes, also known as matrix barcodes, are more advanced and can store information both horizontally and vertically. They use patterns of squares, dots, or other geometric shapes to encode data. Unlike 1D barcodes, which are read in a single line, 2D barcodes can store much more information, including alphanumeric characters, and can be read from any angle. Examples of 2D barcodes include QR codes (Quick Response codes), Data Matrix, and PDF417. 2D barcodes are commonly used in applications such as mobile payments, ticketing, and document scanning.

How do barcodes work?

Have you ever wondered how barcodes work? The answer lies in their encoding process. At their core, barcodes are a way of storing information in a pattern of parallel lines and spaces of varying widths. This pattern represents a specific character or piece of data, and the barcode scanner uses it to decipher the information stored in the barcode. To read the information, the scanner emits light onto the barcode, which reflects back differently depending on the widths of the lines and spaces. Barcodes are a fast, efficient, and reliable resource for small businesses to collect and track data and make customer transactions quick and seamless.

What types of plastic cards work well with barcodes?

Any card that requires identification, tracking, or transactional functionality can utilize barcode technology. Some plastic cards that commonly use barcodes include:

  • Gift Cards
  • Loyalty Cards
  • Membership Cards
  • Library Cards
  • Access Control Cards
  • Event Badges
  • Student ID Cards
  • Health Insurance Cards
  • Discount Cards

How do I know if I should use a Barcode or a Magnetic Stripe?

Choosing between a barcode and a magnetic stripe for your cards depends on several factors related to your specific use case, system requirements, and goals. Here are some considerations to help you decide if utilizing a barcode is the best fit for your needs:

Ease of Implementation: Barcodes are easy to generate, print, and implement. Standard barcode scanners are widely available and affordable.

Cost-Effectiveness: Barcodes are a cost-effective solution for card production and the equipment required for scanning.

Versatility: Barcodes are versatile and can be used in various applications, such as retail, inventory management, and event tickets.

Data Capacity: While limited compared to some technologies, barcodes are suitable for storing moderate amounts of data, such as product IDs or membership numbers.

Widespread Adoption: Barcodes are widely accepted and standardized, making them compatible with various systems and industries.

Ease of Reading: Barcodes are easily readable by standard barcode scanners, facilitating quick and efficient data entry.

Durability: While not as durable as some alternatives, barcodes are suitable for applications with moderate wear and tear.
