What is a Barcode?

A barcode is a machine-readable optical label that contains information about the item to which it is attached. Visually, a barcode is a series of vertical black and white lines of varying thicknesses.

Barcodes aren’t just for shopping; they can be used in any business. In addition to the lines, barcodes also contain numbers that provide information about a product. These numbers in a barcode include:

Number System Character (NSC)

The Number System Character (NSC) is a digit in the UPC (Universal Product Code) barcode system that indicates specific types of barcodes. UPC is widely used in industries, especially in America and Canada. In a UPC barcode, the NSC is usually located at the far left of the barcode. Here’s what each digit means:

  • 0: Standard UPC number
  • 1: Reserved
  • 2: Random weight items
  • 3: Pharmaceuticals
  • 4: In-store code for retailers
  • 5: Coupons
  • 6: Standard UPC number
  • 7: Standard UPC number
  • 8: Reserved
  • 9: Reserved

Guard Bars

There are three guard bars placed at the beginning, middle, and end of a barcode. The start and end guard bars are written as “bar-space-bar” or “101”. Meanwhile, the middle guard bar is written as “space-bar-space” or “01010”.

Manufacturer Code

The manufacturer code consists of a five-digit number that identifies the product’s company of origin. This code is assigned and protected by the Uniform Code Council.

Product Code

The Product Code is a 5-digit number assigned by the company for each product they produce.

Check Digit

The check digit is located on the right side of the barcode. This check digit is used to validate that the other digits have been read accurately.

Benefits of Barcodes

Barcodes are more than just random codes; they offer numerous benefits. Here are some key advantages of barcodes, especially for businesses:

1. Accelerate Transaction Processes

Barcodes can be printed directly on product packaging, making data input much faster and easier compared to manual methods. There are no more errors in typing product codes or numbers during transaction processes.

2. More Accurate Data Retrieval

In addition to speed, data retrieval using barcodes is also more accurate. This is useful for improving employee performance by enabling faster and more accurate work.

3. Versatile Applications

Barcodes aren’t limited to product tags in supermarkets; they can also be used for book publishing, non-retail applications, pharmaceutical identification, asset tracking, inventory management, laboratory data, and even identification cards or memberships.

4. Cost Reduction

Barcodes are advantageous because they are easy to implement and inexpensive. The media used is simply paper and ink. Barcode scanners are also widely available on the market at relatively affordable prices.
