QR code

An abbreviation for quick response code. It is a type of two-dimensional code, also called a matrix bar code, that has large data storage capacity and can be decoded at high speed. QR codes are square, with black patterns on a white background and can be encoded to contain all types of data, for example information in alphanumeric or binary form.

Initially created for the automotive industry, QR codes have become an increasingly popular way for companies in a variety of industries to provide information and offers to their customers and prospects. Many of today's mobile phones are capable of reading QR codes.
