More and more it’s becoming commonplace to see a QR code – or “QR barcode” – in all sorts of places. In part that’s because there is a free app for nearly every smart phone that includes a QR code reader (most bar code scanner apps also include a QR code scanner). Also, it’s pretty easy to make a QR code; you just go to a QR code generator website, plug in your info, and voila, you have your very own QR code.
