This Telefónica Open Gateway whitepaper introduces the SIM Swap API, designed to fight identity fraud by detecting anomalous SIM swap events. It strengthens 2FA, detects fraud in real time, and secures account creation by monitoring SIM changes. The standardized CAMARA API ensures simplified integration and uniform access across telcos, improving developer experience. Use cases include banking (TAN verification), healthcare (EHR access), social networks (account takeover protection), and general fraud prevention. By adding SIM-level intelligence, organizations can block account takeovers, reduce identity theft, and boost trust in digital services.
