QR Code (Quick Response) is a mobile phone readable bar code that can store plain text, website URL's, SMS, phone numbers, e-mail addresses, visiting card (vCard), contact and pretty much any other alphanumeric data.
What is QR Code?
A QR code, short for Quick Response code, is a two-dimensional barcode that can be easily scanned by a smartphone or QR code reader. It was first created in 1994 by a Japanese corporation named Denso Wave as a means of tracking vehicles during the manufacturing process. Today, QR codes are widely used in advertising, marketing, product labeling, and many other applications.
A QR code consists of a square pattern of black and white dots, which encode information such as a URL, text, or other data. When scanned by a smartphone or QR code reader, the code is quickly decoded, and the information is displayed on the device's screen. QR codes can store much more information than traditional barcodes, and they are much faster and easier to scan. They can be printed on almost any surface, including paper, plastic, and metal, and can be used for a wide variety of applications.
