DTMF Masking Solutions

If your business takes card payments, our DTMF masking solutions allow contact centre agents to securely handle payment data and provide first-class customer service.

What is DTMF Masking?

Dual Tone Multi Frequency (DTMF) masking technology works by masking telephone keypads at the point a payment is required. As the sensitive data never reaches the call handler, DTMF masking is considered to be a highly secure payment technology method.
