QR code comeback

Social Media

QR codes, or Quick Response Codes, were first invented in 1994 to track vehicles during manufacturing. Now you see them on advertisements, television, and they've been adapted to share social media profiles. Of the uses for QR codes, the most prevalent would be the "Snapcode" which is a Snapchat specific QR code that allows users to easily add new people to their Snapchat. Other companies are trying this as a way to make connecting easier, like the new Facebook Messenger and Kik codes. While the technology isn't new, good uses for it are. QR codes may not have caught on in the past because marketers never thought about effective places to use them, as seen in the website WTF QR CODES. What I believe QR codes will make a comeback with is generating codes on your phone for use at businesses. It can be used in the same way as a rewards card, but without having to remember your card or enter a phone number. A use that will come up in the future will be the use of QR codes with AR (Augmented Reality). Another use for QR codes, that might actually be a good idea, is for products with GMOs, as explained in this WIRED article
