Interesting think-piece here by Rick Howe at Tracy Swedlow’s Interactive TV Today.
Rick wonders if the use of QR codes might take off on (US) TV as a way of enabling secure purchases via smartphones in response to a TV screen prompt. His article contains a number of video-grabs of US examples of such applications.
Rick bases his argument on the growing popularity of QR functionality in mobile phones.
QR codes (short for Quick Response codes) are a high-data-content variation on barcodes (see here).
They can be captured and analysed by phone camera software, triggering a link to a relevant website.
As an example, the QR code below contains a link to farncombe’s website (www.farncombe.com).
