For those that don’t know, foursquare is a geolocation tool that serves as a friend-finder, social city guide, and a game that challenges users to experience new things such as donating blood. It also rewards them for doing so.
Starting today, you can unlock a special badge on foursquare by “checking in” to your blood donation location and then using a combination of the words “blood” “donate” and “Red Cross” when you “shout” what you’re doing at the “check-in” location. You must use the words “blood” and “Red Cross” along with any form of the word “donate” (i.e. – donate, donated or donating).
For example, a blood donor might walk into a college blood drive, “check-in” to the student center, and then “shout”: “I’m donating blood with the Red Cross” in order to unlock the Red Cross blood donor badge. The donor’s “check-in” and “shout” can also be shared with friends on Facebook and Twitter.
The foursquare app is available for BlackBerry, iPhone, and Android. Go forth, donate, and be rewarded!
