In the past, it was only possible to offer security against online attacks and fraud at the price of convenience and data privacy. The Payfone Fonebook is a framework for digital identity that delivers the highest levels of security while also creating more user-friendly and privacy-centric experiences.


  • Transform your digital experience with deterministic digital identity that continuously updates to capture the 8 million customer change events (device changes, ports, SIM swaps, phone number changes) that occur each day
  • The Fonebook is the world’s only solution that binds customer IDs with anonymous identity tokens to instantly authenticate digital transactions without passing PII (personally identifiable information)
  • Payfone’s patented platform is built upon the same technology that allows you to use your mobile phone anywhere in the world without having to log in, but extends this capability to all digital channels (mobile, PC, tablet, chat and call center)
