QR codes have become common in consumer advertising. Typically, a smartphone
is used as a QR code scanner, displaying the code and converting it to some useful form (such as a standard URL
for a website, thereby obviating the need for a user to type it into a web browser
). QR code has become a focus of advertising
strategy, since it provides a way to access a brand's website more quickly than by manually entering a URL. Beyond mere convenience to the consumer, the importance of this capability is that it increases the conversion rate
(the chance that contact with the advertisement will convert to a sale), by coaxing interested prospects further down the conversion funnel
with little delay or effort, bringing the viewer to the advertiser's website immediately, where a longer and more targeted sales pitch may lose the viewer's interest.
