Have you ever noticed those black and white vertical lines accompanied by numbers on product packaging? That’s a barcode, a simple yet powerful code used to store specific data like product codes, expiration dates, or identification numbers.
Barcodes are incredibly useful for quickly and easily storing information about an item. They remain a staple in various industries due to their speed and ease of use when scanned.
Interested in learning more about how to scan barcodes? Let’s dive into this comprehensive guide!
What is a Barcode?
A barcode, essentially a “bar code,” is a visual representation of data that machines can read. Typically printed on labels or directly onto product packaging, barcodes consist of a series of parallel lines of varying widths and spaces. These patterns represent numbers and other symbols that, when scanned, translate into specific information about the product.
Beyond retail, barcodes are versatile tools used across diverse sectors. Along with the visual lines, barcodes also include numbers that provide further details about the item. These numbers follow a standardized structure, including elements like:
Number System Character (NSC)
The Number System Character (NSC) is a single digit at the beginning of a UPC (Universal Product Code) barcode, primarily used in North America. It indicates the type of product or the barcode’s purpose. Here’s a breakdown of common NSC digits:
- 0 & 6 & 7: Standard UPC numbers for most retail products.
- 2: Used for random weight items, like produce or meat, where the weight determines the price.
- 3: Specifically for pharmaceuticals.
- 4: In-store codes used by retailers, often for items weighed or packaged in-store.
- 5: Coupons.
- 1, 8, 9: Reserved for future or specific uses.
Guard Bars
Guard bars are essential for barcode scanners to correctly read the code. There are three sets: start, middle, and end guards.
- Start and End Guard Bars: These are identical “bar-space-bar” patterns, represented as “101” in binary. They signal the beginning and end of the barcode to the scanner.
- Middle Guard Bars: Located in the center of the barcode, these are represented as “space-bar-space-bar-space” or “01010”. For UPC-A barcodes, they separate the left and right halves of the code.
Manufacturer Code
The Manufacturer Code is a five-digit number that uniquely identifies the company that made the product. This code is assigned and regulated by organizations like the GS1 (formerly Uniform Code Council) to ensure each manufacturer has a distinct identifier.
Product Code
Following the Manufacturer Code, the Product Code is another set of five digits. Assigned by the manufacturer, this code is specific to each product they produce. It differentiates individual items within a company’s product line.
Check Digit
The Check Digit is the final digit on the right side of the barcode. It’s a calculated digit used to verify the accuracy of the scanned barcode. The scanner performs a mathematical calculation on the preceding digits, and if the result matches the check digit, it confirms the barcode was scanned correctly. This helps reduce errors in data entry.
Benefits of Barcodes
Barcodes offer numerous advantages, especially for businesses, streamlining operations and improving efficiency. Here are some key benefits:
1. Faster Transaction Processing
Printed directly on product packaging, barcodes drastically speed up data input compared to manual entry. At checkout, scanning a barcode is much quicker than typing in product codes, leading to faster transaction times and reduced queues. This efficiency is crucial in retail environments and any high-volume transaction setting.
2. Improved Data Accuracy
Scanning barcodes minimizes errors associated with manual data entry. Human error is significantly reduced as scanners accurately capture the encoded information, leading to more reliable inventory management, sales tracking, and overall data accuracy. Accurate data improves decision-making and reduces costly mistakes.
3. Versatile Applications Across Industries
Barcodes are not limited to retail; their applications span various industries. They are used in:
- Publishing: For book identification and inventory.
- Non-Retail Sectors: In manufacturing for tracking parts and components.
- Pharmaceuticals: For medication identification and tracking, ensuring patient safety and preventing errors.
- Asset Tracking: For managing equipment and resources within organizations.
- Inventory Management: For efficient stock control and monitoring product movement.
- Laboratory Data: For sample tracking and management in scientific settings.
- Identification and Membership Cards: For access control and member management.
4. Cost Reduction
Implementing barcode systems is cost-effective. The media used (labels, ink) are inexpensive, and barcode scanners are readily available and affordable. The efficiency gains and error reduction further contribute to cost savings in the long run by optimizing processes and minimizing losses due to inaccuracies.
How to Scan Barcodes on Your Phone Using a Browser
