What are QR Codes?

What are QR Codes? | Hitrendsetter

So, QR codes are these funky square barcodes you’ll be able to scan with your phone or a special gadget. They’re like regular barcodes on steroids – way more information stuffed into a little space. Whereas old-school barcodes can only hold a bit of information in one heading, QR codes cram in tons more stuff from all angles. Instead, QR codes can hold data both horizontally and vertically.

1. Anatomy of a QR Code

• Finder Patterns: Three large squares in the corners that help scanners locate the QR code.

• Version Information: Specifies which version of the QR code is being used.
• Data and Error Correction Keys: The actual information encoded in the QR code.
• Quiet Zone: The blank margin around the QR code, crucial for proper scanning.

2. Encoding Process

• Data Encoding: Information is converted into a binary string.
• Error Correction: Additional data is added to allow for successful scanning even if parts of the code are damaged.
