I was just checking up on Google charts this morning to see what was new. They now support QR codes, another barcode format that you might need in your outputs at some point.
similar to datamatrix barcodes, its used to store large amounts of data. Kudos to someone that can decipher the contents of the code on the left (no cheating folks :)
To quote Google,
QR codes are a popular type of two-dimensional barcode. They are also known as hardlinks or physical world hyperlinks. QR Codes store up to 4,296 alphanumeric characters of arbitrary text. This text can be anything, for example URL, contact information, a telephone number, even a poem! QR codes can be read by an optical device with the appropriate software. Such devices range from dedicated QR code readers to mobile phones.
Calling the code is a simple URL away, embedding it in your outputs, even simpler. No font files to load just create a field or dumy image with a URL pointing to the Google charts API. More information from Googlehere.
