QR Codes to Help Drunk Guys Get Home

In some Michigan bars, coasters outfitted with QR codes bring up a list of cabs in the area

Perhaps QR codes can be used for more than just weird marketing gimmicks; a new initiative in Michigan has created coasters printed with QR codes that will bring up a list of cab services.

The Office of Highway Safety Planning hopes this will reduce drunk driving in the area, as well as appeal to supposedly tech-savvy young adults.

Of course, reports have shown that college kids really don't know how QR codes work, and the measure doesn't seem to address the perils of drunk walking, but it's still a smart idea, especially around crazy drinking holidays like St. Patty's Day tomorrow. In the meantime, here's a quick guide on how to cure a hangover.
