I was an early proponent of QR Codes, but now I have to admit that they are history. Invisible ink and augmented-reality apps are replacing the clunky codes. The new technology is superior in that you don’t have to take a picture of the code, which then records your contact information and sends you to a website, video or document, or sends you a text message giving a web address. With the new apps, you just run your smartphone over the content and get the enhanced features immediately.
B.L. Ochman hits the nail on head in this analysis of QR vs. AR and other technologies.
