Understanding Barcodes
A barcode, or bar code, is essentially a visual representation of data that can be read by machines. Typically printed as stickers or directly onto packaging, barcodes consist of a series of black and white vertical lines of varying thicknesses.
Barcodes are not limited to retail; they are used across various industries. Beyond the lines, the numbers beneath a barcode provide further information about the product. These numbers are structured into different segments, including:
Number System Character (NSC)
The Number System Character (NSC) is a digit in the UPC (Universal Product Code) barcode system that indicates specific categories. UPC is widely used in industries, especially in North America. In a UPC barcode, the NSC is usually the leftmost digit. Here’s what each digit signifies:
- 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 located at the beginning, middle, and end of a barcode. The start and end guard bars are represented as “bar-space-bar” or “101”. The middle guard bar is represented as “space-bar-space” or “01010”.
Manufacturer Code
The Manufacturer Code is a five-digit number identifying the product’s manufacturer. This code is assigned and protected by the Uniform Code Council.
Product Code
The Product Code is a five-digit number assigned by the company to each specific product they produce.
Check Digit
The check digit is located on the far right of the barcode. It’s used to validate the accuracy of the other digits read during scanning.
Benefits of Barcodes
Barcodes offer numerous advantages, particularly for businesses. Here are some key benefits:
1. Faster Transaction Processing
Barcodes printed directly on products significantly speed up data entry compared to manual methods. They eliminate errors in manually typing product codes or numbers during transactions.
2. More Accurate Data Retrieval
Scanning barcodes ensures faster and more accurate data retrieval. This improves employee efficiency by enabling quicker and more precise work processes.
3. Versatility Across Industries
Barcodes aren’t just for supermarket products. They have diverse applications, including book publishing, non-retail sectors, pharmaceutical identification, asset tracking, inventory management, laboratory data, and even identification cards or memberships.
4. Cost Reduction
Barcodes are a cost-effective solution due to their simplicity and inexpensive printing requirements—just paper and ink. Barcode scanners are also widely available and relatively affordable.
