QR codes
What is a QR code?
A QR code (Quick Response code) is a type of two-dimensional barcode that stores data like URLs, text, or contact info. It can be scanned using a smartphone or QR reader to quickly access digital content or perform actions.
How do QR codes work?
QR codes work by encoding data in a pattern of black and white squares. A scanner, like a smartphone camera, reads the pattern and translates it into readable information, such as a website link, text, or contact details.
What do the black and white squares mean?
The black and white squares in a QR code represent encoded data. The black squares are binary “1"s, and the white spaces are “0"s, together forming a pattern that can be interpreted as a URL, text, or other information.
Why is the white space around QR codes important?
The white space around QR codes, called the “quiet zone,” is essential for proper scanning. This border helps scanners distinguish the QR code from surrounding content and ensures accurate detection of the code’s boundaries. Without adequate quiet zone, scanners may fail to read the code.
Picture QR code
What are picture QR codes?
Picture QR codes are customized QR codes that are weaved into images, logos, or designs. They maintain their scannability while adding a visual element that can enhance branding and aesthetics.
How do they work?
Their base is any image you choose. The QR code pattern is then integrated into the image, adding your data. It works by reducing the traditional black and white squares to a minimum, while ensuring the QR code remains functional and scannable.
Can they always be scanned perfectly?
Yes, picture QR codes can usually be scanned successfully, but factors like device type and lighting conditions can affect performance. It’s best to test the QR code with multiple devices and apps to ensure reliable scanning in your specific situation.
