DataCash, global payments services provider, has announced that its fraud management solution (GateKeeper 2.0) will be the first of its kind to integrate MasterCard's Lost-Stolen Account List API. The MasterCard API cross-references over 30 million lost and stolen cards globally. The integration will empower merchants with greater fraud detection capabilities and lessen the potential to reject legitimate customers.
MyBantu is an interesting little mashup, available as an iPhone app, an Android app, and a website. Its goal is to make shopping for anything, especially restaurants and movies, easier and more social. It uses Yelp API, Netflix API and various others to make it happen. It's very similar in idea to Siri, the "ultimate mashup" that Apple later gobbled up in the largest mashup acquisition ever.
