Barcodes and QR codes are machine-readable codes used to store information in a visual pattern that can be scanned using barcode scanners, mobile phones, or POS systems.

📊 What Is a Barcode?

A barcode is a pattern of parallel black lines and spaces that represents numeric or alphanumeric data.

• Each line pattern corresponds to a specific number or character.

• The scanner reads the reflected light from the lines and converts it into digital data.

Common Uses

• Retail product billing (price lookup)

• Inventory management

• Shipping and logistics tracking

• Library systems

Types of Barcodes

• 1D (Linear) Barcodes:
  Examples: UPC, EAN, Code 128

• These usually store limited information (mostly product IDs).

The barcode concept was first developed by Norman Joseph Woodland and Bernard Silver, and later standardized globally by GS1.

🔳 What Is a QR Code?

A QR code (Quick Response code) is a 2D square-shaped code that stores much more data than a traditional barcode.

• It can store text, URLs, contact details, payment links, or product information.

• It can be scanned quickly from any direction using smartphone cameras.

The QR code was invented in 1994 by Denso Wave.

Common Uses

• Digital payments (UPI, wallets)

• Website links and marketing

• Product authentication

• Event tickets and passes

• App downloads
