The humble QR code is showing no signs of letting up in South Africa, with an explosion in popularity.
According to a study by World Wide Worx, the code has become more than just a simple way to add friends on BlackBerry Messenger.
"In the past year, however, it has quietly gained new life as mobile apps like SnapScan roped it in for payments at small merchants, flea markets and the like," World Wide Worx said, adding that it has also been appearing on posters, window displays and other print advertising.
World Wide Worx said that by the end of 2014, over two million South Africans were using QR Codes.
"Of these users, 1.1 million were male, with female users only marginally behind, at 1.04 million."
"Mobile payment systems are quickly becoming mainstream, and it will be fascinating to see how the more mechanical systems like QR Codes compete," said World Wide Worx managing director Arthur Goldstuck.
"Ideally, there should be room for any system, with each one finding its ideal niche. But there are no certainties in a sector that is moving so fast."
