QR codes are essentially the same as the bar codes you find behind items in the supermarket. They're machine-readable and can easily be interpreted by humans once scanned with devices by rearranging the data to its original form.

Although there are several different QR code format, the most important parts include:

1. Data Module - the black and white squares are standard across all QR codes
