I love Opera Mini, not just because of its light size and data saving features, but also because the app keeps getting updated frequently with new things to check out.
This last update for example adds a QR reader and generator to the browser so that you can scan any QR code you might come across and immediately go to the linked page, or create codes to share with nearby users or online. I haven't been seeing lots of QR codes around me lately, but in the 1 or 2 instances where I came across them, I wished I could scan them easily.
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.
All you have to do is open the caast.me website on your computer, then click the share menu on your Android device, select CaastMe, and scan the QR code.
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.
The web tool provided by Esponce relies on the fact that some of the lines in a QR code don't actually contain the information needed to decode it.
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.
The last feature is the one that has everybody talking - Google Goggles is now capable of scanning and solving Sudoku puzzles in a matter of seconds.
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. Unfortunately, that's not the case here; rather, the technology will allow the Nexus S (and other NFC-capable Android phones) to act as a glorified barcode scanner of sorts.
