what's this? how does this code thing work?
They are QR codes. From Wikipedia:
Quote:
A QR Code is a matrix barcode (or two-dimensional code), readable by QR scanners, mobile phones with a camera, and smartphones. The code consists of black modules arranged in a square pattern on a 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 abbreviation for Quick Response, as the creator intended the code to allow its contents to be decoded at high speed
Some companies use them to embed product information or the url of their website , so that if you (as a consumer) scan the code with a smartphone and have the decoding software, you get the company's web address. Similar codes are used by the US post office and shipping companies for tracking, addressing and postage. Here we've been encoding messages about Gimp and GimpChat. It's an interesting
article in Wikipedia, including the links to other code types.
Scroll back through this thread for websites to encode and decode, if you don't have another option like a smartphone.
