QR Code can be used for:

● information access (business card, map, WIFI password, data)
● website jump (jump to microblogging, mobile site, website)

QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode) first designed for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached. A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to efficiently store data; extensions may also be used.

The QR code consists of black squares in a square grid arranged on a white background, which can be read by an imaging device such as a camera and processed using Reed-Solomon error correction until the image can be properly interpreted. The desired data is then extracted from the patterns present in the horizontal and vertical components of the image.

Advantage:
1. High density coding, large information capacity.
2. Wide range of coding.
3. Fault tolerance, with error correction function.
4. Decoding reliability is high.
5. Encryption can be introduced.
6. Low cost, easy to produce, durable.
