QR Codes: The new artwork of digital information encoding
So what are those two-dimensional squares that look like art work? Some fan mail from some flounder?
They are QR (Quick Response) codes. One of these squares can embed a lot of information. In fact, you can encode about 4,000 alphanumeric characters in one of these squares. The information can be a URL, a business card, an e-mail address, or any text you want – even a resume. Imagine that, your curriculum vitae in a square on your business card. How about the next generation of tombstone markers? Suppose we etch the story of your life in stone as a QR code that anyone with a mobile device could read as they walked through the cemetery?
QR codes are very easy to generate using software for a PC. Just about anyone with a smart phone that has a camera and application capability can read the messages and information in these artistic squares. If the content of the message is well-formed, a smart device can take an action. For example, open a URL, create a business contact in an address book, send e-mail, or any other action of which the device is capable and can be linked to a directive in the message. Pretty cool. No license required to generate or use these codes.
