And this is one of many reasons that URL shorteners must die. If it weren't for Twitter, people wouldn't be so used to blindly clicking through short URLs. But anyhow, most URL shorteners offer an API to retrieve the long URL. You could implement that in your QR code scanner as well, for the most popular URL shorteners, to allow people to see where they will be redirected to.

And cell phones don't display long URLs, another phishing problem begging to be exploited
