Facebook has nearly captured the market for 1 billion social media users so it only makes sense that some of the countries top brands would want to turn that loyalty to the network into a rewards program and that’s exactly what’s happening at Dunkin’ Donuts, Red Robin, Taco Bell and Quiznos.

Those company’s have signed deals with loyalty marketing start-up Plink who will announced a new quick-serve brand test for partners on Thursday.

The program works by tracking how much money Facebook users spend at each location and then rewarding them with Facebook Credits which can be used to make in-app purchases in such games as CityVille and FarmVille.

To get started users simply register their credit or debit card at Plink.com and then when they use that specific card at participating locations they receive Facebook credits. 

Speaking to ClickZ Plink co-founder Peter Vogel said the company will target Facebook ads at people who have already “liked” the brands on the social site. Plink will also appear in various paid ads on different games to help gain early traction for the platform.

Do you like the concept behind Plink? Given how simple they’re making it to join the program it could be a great addition to cash back rewards, airline miles and other perks you might already have available to you through your credit card provider.
