You’ve probably seen them on posters, magazines, business cards, at movie theaters, at restaurants and other businesses, but what they heck are these weird boxy black-and-white images with all these lines and dots? In this week’s Techie Tip, I’ll talk about 2 online tools you could use to create QR codes like this:

QR (“Quick Response”) codes have been around for years (invented in 1994 by a Toyota subsidiary) and are used to encode words, URLs (web content links), or other data into a machine-readable image representation of data.

Modern smartphones, scanners, and other barcode readers can be used to scan, and then use these codes.

For example, if you have a QR reader on your iPhone, Android, or other smartphone, you could launch the reader, point your camera at the QR code above, and your web browser should redirect you back to this blog post (it’s a representation of the URL http://www.stanford.edu/group/ttsclasses/cgi-bin/techietips/?p=293).

So, how can you create QR codes? In addition to be great ways to shorten long URLs, these online URL shorteners will also generate a QR code every time you use their service.
