Amazon's got a new way to buy stuff for anyone who has a Kindle Fire. Amazon Coins are a virtual currency that will come out in May, and work for all app and in-app purchases on the Kindle Fire.
The Coins will function exactly the same as real money, and developers will still get their standard cut. Amazon thinks it will help drive more business, and that makes some sense. Especially with apps and games for kids, it seems like a nice addition where you can maybe set up a Coins purse without allowing access to another payment method. And since Amazon will obviously never stop accepting real money—unlike virtual currency-only merchants like Xbox Live—you don't have quite the locked-in headache here, either. [Amazon]
