I’m seeing an increasing number of businesses in China hiring talented designers to help jazz up their WeChat QR codes. Just take a look at the work of art below. Read on to see 12 really impressive QR code designs and learn how WeChat actually recognizes QR codes.
Go on. Scan it 😉
Wait, how does WeChat actually recognize something as a QR code?
There are always three distinctive squares at the corners of the QR code image, with a smaller square (or multiple squares) near the fourth corner to normalize the image for size, orientation, and angle of viewing. The small dots throughout the QR code are converted to binary numbers and validated with an error-correcting algorithm.

QR codes have built in error correction. It’s possible to create artistic QR codes that still scan correctly, but contain intentional errors or colors, logos, and other features into the code. Technically, it is possible to mathematically compute which boxes in a QR code are the buffers that can be removed, but such computations are generally unnecessary. By applying a simple process of trial-and-error, anyone can begin applying their design techniques to a code and then test for scannability.
Below are more examples of innovative QR code design:
The Chinese bike sharing giants, Mobike and Ofo also have their own particular way of jazzing up their QR codes.
