The new Facebook gift cards will be available in values of $15, $25 and $50 at all of Target's 1,750 retail stores and at Target.com.
And just in time for holiday dollars, two or three more national retailers will start selling the cards in coming months.
This will be the first time Facebook has had any presence in a retail store. Facebook already has an arrangement with online-payment services PayPal and MOL to purchase Facebook Credits.
The 500 million members of Facebook can use their Facebook Credits to buy virtual goods, play social games and make donations to charity.
By year's end, Facebook expects to have gift card credits available for its thousands of games. At least 19 games on Facebook have more than 10 million active users a month.
Facebook's entry into the growing prepaid gift card market could prove lucrative. The domestic prepaid gift card market is expected to reach $86.2 billion this year, compared with $80.6 billion in 2009, according to Mercator Advisory Group.
