QR (Quick Response) codes are like bar codes that can easily by mobile devices through cameras. They have become increasingly popular for transferring information to your phone.
The first time I saw it was when I downloaded the new Blackberry Messenger. Now instead of sending PINs to your friends, you can flash your QR code and they can take a picture of it. In practice, it’s a little weird and imprecise (requiring several tries and a steady hand), but a neat adaptation of the technology. Google is using it on stores and restaurants so that users can take a picture of the QR code and have all the information from Google at their fingertips. Even Microsoft’s new app that I wrote about recently is a take on the QR code. While Microsoft’s may look a little different than the traditional ones, it works in much the same way.
Today Tech Crunch broke a story about Facebook’s experiments with the QR codes. There are options on some users’ profiles to generate either a QR code for your profile or status. While I am not certain of the application, I think it’s cool that Facebook is experimenting. Much like trading business cards, QR codes could hold the future of exchanging personal information.
I am interested to see how they use the codes and how other companies incorporate them.
