Big Q(R)
It’s not often that I learn something when I am sick. Usually, I try and recuperate as quickly as possible so I can get back on my feet again. Sometimes, that means depending on sleepy time meds, so it was while I was trying to temp my body to pass out that I noticed the QR code on the back of my NyQuil bottle.
QR codes, or Quick Response, are a multidimensional bar code which looks like a pixelated UPC and has layered data embedded that can be decoded via a program on your mobile. Usually, it’s as easy as taking a photo or scanning the code with a mobile app. Consider tallying your shopping items while you pick things up, only to have your order zapped to the cashier for quicker purchasing (or purchasing via a digital wallet). Scan a QR code in a movie poster and view the trailer on your mobile right away. For more on QR codes, read up on Wikipedia’s QR codes entry or Wired’s QR introduction from back in 2004.
