QR code definition: QR code – short for Quick Response Code – is a piece of code that can be read by smartphones and cameras.
QR codes are typically made up of white and black squares and are similar to the barcodes you would find on retail products:
The code stores information and files – most commonly URLs – that can easily be scanned by a QR reader app on a mobile device; scanning the code takes them to the relevant webpage.
QR codes are often used in print-based marketing, such as leaflets, so potential customers can easily be taken to a relevant webpage or online offer.
