There are no shortage of ways to get links from one device to another, but this often involves signing up for a service and leaving behind a record of what you're sharing. CaastMe is a new Android app that has an innovative way of getting around this, account-free.
The software relies on QR codes, but it uses them in the opposite of the way you would expect. Instead of prompting your device to open a URL, CaastMe tells the computer displaying the code where to go.
QR codes are finally starting to show up around town, but we've all known about them for some time, right? Well if you want to stay ahead of the curve and keep wowing regular people with your mobile expertise, why not start adding images to your QR codes? Esponce is a company that's in the business of selling QR code tracking and marketing, but part of the service is freely available, and you can use it to really spice up your QR codes.
Google just updated its Goggles app to version 1.3 and added three noteworthy features that make it even more desirable than it was before. First is the ability to scan QR codes without actually taking a picture; just hover your camera over the image and Goggles will automatically recognize it.
Second, Goggles now recognizes ads in major US newspapers and magazines. I couldn't get this to work, but Google claims it will work with any ads dated since August 2010.
Update 2/9/11: Writing/transmitting via NFC is now possible thanks to the 2.3.3 update.
One thing that was very much anticipated in the Nexus S and Gingerbread in general was NFC (Near Field Communication) support, which is a feature we've never seen before on an Android device. In fact, the vast majority of us took it to mean that it will allow you to use your phone as a credit card, which would indeed be very exciting and insanely cool.
