US retail giants Walmart and Best Buy have begun selling gift cards loaded with Facebook Credits, used as a universal currency for all games and apps on the social networking site.
The two chains will be joining the Target group in the scheme - Target started selling the cards around a month ago. Each retailer has different selection of pre-paid values available, with Target offering $50, $25 and $15 cards, Walmart $25, $10 and $5 and Best Buy $50, $35 and $10.
Over 75 developers running more than 250 games have signed up to use the Credits, including Farmville creator Zynga - despite the developer registering a patent for its own virtual currency, too.
Recently, Facebook partnered with PlaySpan to help manage the Credits scheme and make more payment options available.
