Understanding Barcode Scanning Technology for Business and Everyday Operations
Learn How Barcode Scanners Work, Where They Are Used, and How to Choose the Right Solution
Barcode scanners are among the most widely used data-capture technologies in the world. They help businesses identify products, track inventory, manage assets, process shipments, and improve operational accuracy.
From retail stores and supermarkets to warehouses, hospitals, manufacturing facilities, and logistics operations, barcode scanners play an important role in collecting information quickly and accurately.
This guide explains what barcode scanners are, how they work, the different types available, and the factors businesses should consider when selecting a scanning solution.
What Is a Barcode Scanner?
A barcode scanner is an electronic device that reads information encoded in a barcode and converts it into digital data that can be processed by a computer, mobile device, point-of-sale system, or business application.
Instead of manually entering numbers or product information, users can scan a barcode and instantly retrieve the associated data.
Barcode scanners are commonly used for:
- Product identification
- Inventory management
- Asset tracking
- Warehouse operations
- Shipping and receiving
- Healthcare identification
- Manufacturing processes
- Retail transactions
How Does a Barcode Scanner Work?
A barcode scanner typically performs three functions:
1. Capture
The scanner captures an image or reflected light pattern from the barcode.
2. Decode
The scanner interprets the barcode pattern and converts it into usable information.
3. Transfer Data
The decoded information is sent to a computer, mobile computer, tablet, POS system, or software application.
The entire process usually takes a fraction of a second.
What Is a Barcode?
A barcode is a machine-readable representation of information.
Barcodes contain numbers, letters, or other identifiers that can be read electronically.
Common examples include:
- Product codes
- Serial numbers
- Asset identifiers
- Shipment references
- Inventory numbers
- Patient identification numbers
Types of Barcodes
1D Barcodes
One-dimensional (1D) barcodes use vertical lines and spaces.
Examples include:
- Code 128
- Code 39
- EAN
- UPC
Common uses:
- Retail products
- Shipping labels
- Inventory identification
Advantages
- Widely used
- Easy to print
- Supported by many systems
2D Barcodes
Two-dimensional (2D) barcodes store information both horizontally and vertically.
Examples include:
- QR Codes
- Data Matrix
- PDF417
- Aztec Codes
Common uses:
- Manufacturing
- Healthcare
- Mobile applications
- Product traceability
Advantages
- Can store more information
- Better error correction
- Smaller print size possible
