From Wikipedia: “A QR Code is a matrix barcode (or two-dimensional code), readable by QR scanners, mobile phones with camera, and smartphones. The code consists of black modules arranged in a square pattern on white background. The information encoded can be text, URL or other data.
Common in Japan, where it was created by Toyota subsidiary Denso-Wave in 1994, the QR code is one of the most popular types of two-dimensional barcodes. QR is the initialism of Quick Response, as the creator intended the code to allow its contents to be decoded at high speed.”
Someone posted a link on a qrp forum I follow this morning that pointed to a video about QR Codes. I have never seen them before, but they seem quite interesting. They are readable by mobile phones, I have not been able to find an online reader. Anyone know of one? Just want to try it out.
