What Is a QR Code?
QR code stands for Quick Response code. It is a type of barcode that can store information in a two-dimensional pattern. Unlike traditional barcodes, which hold data only in one dimension, QR codes can store much more information in a compact space.
QR codes can contain:
- URLs for websites or social media
- Contact information (vCard)
- Text messages
- Wi-Fi login credentials
- Payment or ticket information
These codes can be scanned by a smartphone camera or a QR code scanner app, instantly displaying the stored information.
How QR Codes Work
A QR code works by encoding information into a matrix of black and white squares. When scanned, the device’s QR code reader interprets the pattern and translates it into readable content.
The QR code contains error correction, allowing it to remain readable even if partially damaged. This makes it reliable for both digital and physical use, such as printed flyers or online documents.
Types of QR Codes
There are several types of QR codes, each serving different purposes:
- Static QR Codes
- Fixed content that cannot be changed after generation
- Best for URLs, contact info, or simple text
- Dynamic QR Codes
- Content can be updated after creation
- Trackable and analytics-enabled
- Ideal for marketing campaigns
- vCard QR Codes
- Store personal or business contact information
- Can be scanned to save directly into a phone’s contacts
- Wi-Fi QR Codes
- Allows users to connect to Wi-Fi networks instantly
- Useful for cafes, events, or classrooms
- Payment QR Codes
- Used for quick digital payments
- Supports apps like PayPal, Venmo, or local payment systems
By understanding the type of QR code you need, you can choose the right tool and format for your purpose.
