Have you started noticing these weird looking 2D bar codes? You can get an app for your smart phone which will read the code and do something – like take you to a web page with more information. Google is using them as part of their Places program. Here’s an example – a QR code that will take you to the InMenlo home page! Wowee!
Need a QR code app for your iPhone? The Google search app will work – select the Camera icon and take a picture of the QR code. But specialized apps like i-nigma Reader work fast – and are available free for the Apple iPhone, Android or Blackberry smart phones.
