What is QR code?
A QR (Quick Response) code is a two-dimensional bar code that can
be read by a mobile handset. They originate from technology developed
a decade ago when Japanese company Denso Wave created a barcode standard
as an inventory aid for
Toyota Motor factory lines. A QR code can hold 50x more information than a traditional barcode.
However, a QR code is two-dimensional and can be read horizontally and
vertically unlike
traditional barcodes, which can only be read in one direction. A QR code can contain up to
1,000 characters compared to a maximum of 20 characters in traditional barcodes.
