information using their telephone keypad. For complete security, Semafone’s patented technology masks the Dual Tone Multi-Frequency (DTMF) tones from the cardholder’s telephone and replaces them with a flat tone so they can’t be recognised by the call centre agent or recorded on the call recording system. By ensuring all card data remains segregated and by removing sensitive data before it hits the call recorder and the contact centre infrastructure, the contact centre is taken out of the scope of PCI DSS, protected against the risk of opportunistic agent fraud and the associated reputational risk.

Semafone is a PCI DSS Level 1 accredited Service Provider, registered Visa merchant agent and also holds PA-DSS certification for its payment solution.
