What are QR codes

QR code

QR codes are a type of matrix (2D) barcodes. The big difference with the older linear (1D) barcode is that it can contain hundreds of characters. Perfect for storing links or other digital data.

The QR code technology is freely licensed by DENSO WAVE and in the beginning designed for the Japanese automotive industry. Thanks to the fast readability and easy to recognize design we can nowadays find QR codes everywhere.
