A QR Code (Quick Response Code) is a 2-dimensional barcode. When read by a QR code reader on a smartphone, the phone's browser will be directed to the programmed information embedded within the code.
These codes can embed web addresses, phone numbers and other contact information. They create shortcuts to make it easy to engage smartphone users since typing in urls can be extremely tedious. A QR code scan provides a seamless connection to whatever is embedded in the code.
QR Codes can be used on signs, magazines, billboards, buses, business cards, product displays or just about any visual media. Mobile tagging with QR codes is the fastest way to link physical objects to the digital world. Information has never been easier to engage with or share.
