Every product in the supermarket has a unique barcode. It contains information. By scanning it, the checkout assistant quickly knows which product it is and how much it costs.
A QR code is similar to such a barcode. Only it is square and consists of blocks instead of bars. You can also store info in a QR code. By scanning it, you quickly get to see that info. For example, you can get to the right web page in the blink of an eye. QR therefore stands for ‘Quick Response’.
Each QR code has a unique pattern, but a QR code, for example, always has three large squares in the corners. That way, your smartphone quickly knows it is a QR code and what the top and bottom are. That way, it can also read it upside down without making a mistake.
