QR codes can contain much more information
QR Codes or Quick Response Codes are similar to the standard bar codes that currently appear on all types of consumer products, except QR codes can contain much more information than traditional barcodes. QR Codes have been widely used in Japan and Europe in recent years, but are only now starting to gain use with marketers in the United States. Major U.S. businesses that have begun using QR codes in advertising and promotions include Best Buy, Ralph Lauren and Pepsi.
