What is a QR Code?

QR (Quick Response) codes are two-dimensional barcodes that contain information such as text, URLs, email addresses, or even payment details. They were first introduced in 1994 by Masahiro Hara, an engineer at Toyota, to track parts during the manufacturing process.

Importance and Use Cases

QR codes have become increasingly popular due to their versatility and ease of use. Some common use cases include:

• Marketing: Businesses use QR codes on advertisements, flyers, or products to link customers directly to their website, social media, or online ordering platforms.
• Payment: Many businesses, especially in Asia, use QR code payments for easy transactions.
• Information sharing: QR codes are used to share information about products, events, or services.
• Navigation: Some cities use QR codes on street signs to provide directions and information.

How to Open a QR Code on Your Phone

To open a QR code on your phone, follow these step-by-step instructions:

Step 7: Verify the Information (Optional)

If you need to verify any information provided by the QR code, double-check it manually.
