"QR Codes are similar to bar codes making it possible to access Web sites and messages through a camera phone. " This wiki from the University of Wyoming is a great collection of ideas, guides and tutorials.
QR codes are two-dimensional bar codes that can contain any alphanumeric text and that often feature URLs that direct users to sites where they can learn about an object or place (a practice known as "mobile tagging"). Decoding software on tools such as camera phones interprets the codes, which are increasingly found in places such as product labels, billboards, and buildings, inviting passers-by to pull out their mobile phones and uncover the encoded information
This is an ace trick that is simple and if you are needing to produce a load of qr codes or just add a few on the go... Wish I had discovered this one before motm12 ;-)
"Imagine this: you're surfing the web while out at lunch. You decide to buy concert tickets, so to save having to put your sandwich down you ask a passer-by to log in to the ticketing website for you.
As unrealistic as this scenario sounds, users regularly do that when they scan, click and navigate to potentially untrusted internet resources with only a machine-readable matrix - a QR code - to lead the way."
This neat tool from Google, ChartTool is a simple-to-use chart-making service that lets you simply paste in your data and play around with how it looks. It's never been easier to whip up charts that are actually easy to use and update. In fact, embedding these charts on web pages is quite simple thanks to the embed API.
You can even make QR codes in just a few seconds and quickly get an embed code to add it to your website. While ChartTool does not create as many of those fancy 3-D charts that Excel does (it still makes quite a few), it likely will be able to in the future. However, if you're in a rush and need to whip up some exact charts without all the fluff, this is the tool for you.

Thanks to technologies like GPS and QR codes, these games combine real-world experiences with virtual information. The games can capture geo-tagged audio recordings, for example, or photos and videos that student players can view when they reach a particular place or meet a particular character. Characters can talk with students, provide information, exchange items or respond to tasks. Authors can also create virtual items that players can retrieve and exchange.
The key is the ARIS platform, which enables teachers, designers, artists, and students to create place-based narratives. Game designers say the open-source platform is easy to use; educators don't need a programming background to get started because the work is done with an online authoring tool.

"Some owners of Android-powered smartphones in Russia were surprised recently when they tried to download an ICQ chat app by scanning a 2D barcode. What they got instead was an unusually large phone bill after their phone sent a series of SMS messages to a premium texting service, which charges a few dollars per text."
