A quick response (QR) code is made of a matrix of black squares on a white background.
Normal barcodes can hold up to 30 digits. QR codes can hold up to 7000 digits, giving a greater scope of storage.
QR codes can be scanned using an app on your smartphone or tablet. Sometimes companies advertise their content by displaying barcodes in public for people to scan.
Advantage of QR code include:
Users don't need to type a URL, they only need to scan a QR code with an app then they're directed to the website
QR codes can be displayed in trains, buses, magazines and business cards. Making them an effective form of advertising
