Payfone has closed its $11M Series B financing round with investments by Opus Capital, BlackBerry Partners Fund, and RRE Ventures. Bob Borchers of Opus Capital and Kevin Talbot of BlackBerry Partners Fund will join Payfone’s Board of Directors.

Payfone has developed the mobile platform that deploys the capabilities of existing inter-operator networks.

Using Payfone service consumers can pay with only a phone number for purchases that are then billed directly to the consumer’s prepaid or post-paid mobile account. Payfone’s high fidelity platform doesn’t rely on “Premium SMS”, fixed price points or complicated bill presentment. Instead it enables one-click mobile billing for online and mobile purchases globally with real-time fraud prevention and detailed billing records.
