Here’s a review from ZDnet about Plink’s initial launch (in January of this year), which was Facebook-related, so don’t know if that part is still involved:

So, how does it work? First, you have to register your Facebook account with Plink through Facebook Connect. Next, you have to register a credit or debit card of your choice. Finally, you can begin earning Facebook Credits by dining-out or making purchases at participating national restaurants and offline retailers. Today, Plink’s online-to-offline (O2O) loyalty program includes the Dunkin’ Donuts, Quiznos, Red Robin, Taco Bell, and others. Plink members can now earn Facebook Credits at more than 25,000 locations nationwide.

Plink is focusing on national restaurant chains as they represent nearly one-third of the total restaurants in the U.S. and spend significant dollars on marketing and advertising. Plink was designed to be simple and easy to implement: the program requires no POS (Point-of-Sale) integration, no paper coupons to be collected, no staff training, no interruption or slow-down to the normal customer transaction process, no tracking conducted by the restaurant or offline retailer, and no set-up fees, print costs, or other merchandise to purchase. That being said, restaurants and offline retailers have to pay Plink a percentage of the sales generated by Plink members.
