How does a Barcode Scanner Work?

23 Feb.,2024

 

Ever wondered about the magic behind a barcode scanner? This blog unveils the intricate process that powers this seemingly simple yet highly impactful technology. Barcodes, often underestimated, have significantly transformed daily life, especially in the retail sector. The features of barcode readers are impressing small to large businesses and it has thus become a basic need to install Barcode Scanning Systems.

Come, let’s see how does a Barcode scanner works?

What is a Barcode Scanner?

A Barcode Scanner, or barcode reader, is a device equipped with essential components:

  • Light Source: Illuminates the barcode for readability.
  • Lens: Reads the code.
  • Photoconductor: Converts optical information into electrical signals.
  • Decoder: Interprets signals and transmits data to the business’s system.

Together, you can call it a Barcode Scan Engine that scans/reads the code via hardware to software. Barcode solutions are thus a combination of physical devices and software.

Varied Types of Barcode Readers

Depending on business needs, various types of barcode readers exist:

  • Handheld: Corded or wireless, the most common type.
  • Mobile Computers: Cordless with an in-built computer for code processing.
  • Presentation: Hands-free scanners for swift multiple-item scans.
  • In-counter: Set into kiosks or counters for seamless integration.
  • Fixed-mount: Sensor-based readers in factories and processing centres.
  • Wearable: Mounted on the body, often on fingers or arms.
  • Mobile: Modern invention using mobile phones and barcode reader apps.

What are Barcodes used for?

Barcodes encode product details using bars and alphanumeric characters, streamlining the process of item checkout at stores and facilitating efficient inventory tracking in warehouses.

Beyond enhancing ease and speed, barcodes offer significant business advantages such as enhanced accuracy, effective inventory control, and substantial cost savings.

How does a Barcode Scanner work?

While using a barcode scanner may seem straightforward, its functionality is remarkably sophisticated. The process involves five key steps:

  1. The scanner emits light, usually LED or laser, onto the barcode.
  2. Reflected light, captured by a specialized component, distinguishes black and white colours on the barcode.
  3. Moving along the barcode generates an on-off pulse.
  4. The pulse is interpreted and converted into numbers.
  5. Numbers are transmitted to the computer and matched to the corresponding item.

This seemingly simple process has revolutionized both business and customer experiences, streamlining transactions and inventory management.
