Microsoft Tag is collaborating with rapper and producer Diddy in a charitable campaign called the '12 Days Of Tag,' in which $50,000 will be given to charity over a 12 day period. Also participating in this campaign is Unicef.

All you need to do is scan the tag with the Microsoft Tag Reader (downloaded on your smartphone) on the charity's website and vote for it. Share the 12 Days of Tag contest on Twitter using its hashtag #12daysoftag; lucky voters who help out a charity get a chance to win exclusive Diddy products.
