Wow...so cool~!

QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional bar code) first designed for the automotive industry in Japan. Bar codes are optical machine-readable labels attached to items that record information related to the item. It was initially patented; however, its patent holder has chosen not to exercise those rights.Recently, the QR Code system has become popular outside the automotive industry due to its fast readability and greater storage capacity compared to standard UPC barcodes. The code consists of black modules (square dots) arranged in a square grid on a white background. The information encoded may be made up of four standardized types ("modes") of data (numeric, alphanumeric, byte / binary, Kanji) or, through supported extensions, virtually any type of data.

I googled and found some introduction about QR code:

QR Code stands for Quick Response Code. QR Code is a 2D (2-dimensional) matrix symbology which developed first used for automotive applications by DENSO in 1994. QR Code enables customers learn more information about the product or business by scanning the barcode. QR Code could encode numbers, character digits, text, URL, data bytes and images in a relevantly small space. It is widely used in tracking, entertainment and ticketing system at present.
