QR stands for “Quick Response”.

While they may look simple QR codes are actually capable of storing lots of data. But no matter how much they contain, when scanned, the QR code should allow the user to access information instantly – hence why it’s called a Quick Response code.

How do QR codes work?

The patterns within QR codes represent binary codes which can be interpreted to reveal the data stored by the code.

A QR reader can identify a standard QR code based on the three large squares on the outside of the QR code. Once it has identified these three shapes, it knows that everything contained inside the square is a QR code.

The QR reader then analyzes the QR code by breaking the whole thing down to a grid. It looks at the individual grid squares and assigns each one a value based on whether it is black or white. It then groups grid squares together to create larger patterns.

Easy to read

Unlike barcodes, which require special technology to read and interpret, QR codes can be read and understood by smartphones and digital cameras.
