Yesterday, Facebook made the transition from virtual currency Credits to local currency payments. The virtual currency Credit model that started in June 2011 with the hope of making Facebook App payments easier, turned out to make international payments more complex with always changing exchange rates.
Originally, Credits seemed like a good idea for Facebook to earn 30% on game purchases made on the site. One Credit cost $0.10, which could then be used to purchase virtual goods or game currency. Using credits instead of local currency also seemed like a secure way for customers to make transactions with a company they trust rather than an unknown small developer.
