BlackBerry Tag was announced back in October but we haven't really seen much of it in action since. However with the rollout of BlackBerry OS 7.1 to carriers, more users will be able to take advantage of this cool NFC feature on their devices. BlackBerry Messenger 6.1 includes the ability to add contacts via BlackBerry Tag, and you'll be able to do things like send photos, videos, contacts, browser URLs and more via other BlackBerry Tag enabled apps. Check out the video above for a quick walkthrough and to see BlackBerry Tag in action.
