Quick Response (QR) codes have been around since the 90s, and were originally used to track vehicle parts during manufacturing. They’ve since involved to help marketers (by pointing a user to an website), app developers (by pointing users to an app), professionals (by exchanging contact info), and so on. QR codes actually come in multiple formats. The micro QR code can only contain 35 characters once decoded and are much smaller in size that Standard QR codes.
The most information-rich QR code is 177×177 pixels and can contain 1852-4296 characters.
For smartphone users, QR codes can be a quick way to interact with an advertisement or app recommendation. Apps like Google Goggles, available on both Android and iOS, quickly convert QR codes to URLs or other data. There are even specific websites, like YouScan.me, that help with QR code management.
We’re curious…how often do you use a QR code, whether you’re making one (through the many sites that let you plug in a URL and get a QR code), or taking a picture of one while on the go?
