What is a Barcode?

Everything to know about Barcodes

A barcode is a machine-readable representation of data that consists of a series of parallel lines (also known as bars) and spaces of varying widths. These patterns encode information in a format that can be quickly scanned and decoded by barcode scanners or digital devices. Barcodes function as a form of optical, automatic identification technology, allowing computers and databases to retrieve and process information efficiently. Each barcode type follows a specific encoding standard that determines how data is structured within the pattern.

Traditional 1D (one-dimensional) barcodes store data in a linear format, typically representing numerical or alphanumeric characters, while 2D (two-dimensional) barcodes (such as QR codes) can store more complex data, including URLs, text, and contact details. Barcodes streamline data entry and eliminate manual errors by enabling fast and accurate scanning, making them an essential tool in modern automation and digital record-keeping.

Who invented the Barcode?

The barcode was invented in 1952 by Norman Joseph Woodland and Bernard Silver, who were inspired by Morse code. At the time, Morse code used a sequence of dots and dashes to represent information. Woodland and Silver extended this concept by developing a system that encoded data using bars and spaces of varying widths, making it machine-readable. Their invention revolutionized data processing and automation, paving the way for modern barcode technology used across industries worldwide.

Best Practices for Using Barcodes

Barcodes are a powerful tool for improving efficiency, accuracy, and inventory management. However, to get the most out of them, you need to follow best practices to ensure they are easily scannable, properly formatted, and effective for their intended purpose. Here are some key best practices for using barcodes:

✔ Choose the Right Barcode Type

Different barcode formats are designed for specific applications. Make sure to select the correct one based on your needs:

  • UPC / EAN: Ideal for retail products and global trade.
  • Code 128 & Code 39: Best for inventory tracking, logistics, and asset management.
  • Pharmacode: Used in pharmaceuticals for tracking medications.

✔ Ensure Proper Barcode Size & Placement

  • Size Matters – A barcode that is too small may be difficult to scan, while a barcode that is too large may not fit properly on packaging. Follow standard dimensions based on barcode type.
  • Leave Adequate Quiet Zone – The space around the barcode (quiet zone) should be free from any text or design elements to ensure accurate scanning.
  • Position for Accessibility – Place barcodes on flat, smooth surfaces where they can be scanned easily, avoiding edges, corners, and folds.

✔ Use High-Quality Printing

  • Resolution & Contrast: Print barcodes at a high resolution (at least 300 dpi) with sharp, clear lines.
  • Color Combinations: Black on white is the most reliable; avoid using light colors, low contrast, or complex backgrounds.
  • Material Selection: Choose durable printing materials for barcodes used in harsh environments (e.g., warehouses, outdoor logistics).

✔ Keep Data Consistent & Accurate

  • Avoid Special Characters & Spaces – Some barcode formats support only numbers or specific character sets. Ensure your data is correctly formatted.
  • Follow Industry Standards – If using barcodes for retail (UPC/EAN), inventory (Code 128), or shipping (ITF-14), ensure they meet industry guidelines.
  • Test Before Mass Printing – Always verify that the barcode encodes and scans correctly before printing on product packaging or labels.

✔ Regularly Test & Maintain Your Barcodes

  • Verify Barcode Readability – Use different scanners and mobile apps to check if your barcode scans quickly and correctly.
  • Avoid Scratches & Damage – If barcodes are printed on labels, ensure they are resistant to wear and tear to avoid scanning issues.
  • Update Barcodes When Needed – If product details change, ensure the corresponding barcode is updated and correctly linked to new data.

✔ Optimize for Digital & Online Use

  • Use High-Quality PNG or SVG Formats – If displaying barcodes digitally, use high-resolution images for clear scanning.
  • Test on Different Devices – Make sure your barcode scans well on mobile devices and barcode scanners.
  • Add Barcode to Online Product Listings – Helps with inventory tracking and POS integration in e-commerce stores.
