Leaked emails from the Sony hack revealed Snapchat quietly acquired a QR code startup called Scan.me late last year, and now we know why. Yesterday alongside Discover, Snapchat launched a new feature called Snaptags that creates a unique QR code for every Snapchat user. When someone points their Snapchat camera at a Snaptag, the app adds the corresponding person as a friend.
While unnamed in the UI, hacker Graham Smith sniffed the HTTP requests and found the code calls these QRs “Snaptags.”
The feature could solve a big problem for Snapchat: it’s a chore to follow people.
