So what is DTMF?
DTMF stands for Dual Tone Multi Frequency and is the technical name for the tones you hear when you press the keys on your telephone keypad. Your customers would use their telephone keypad to enter card details instead of speaking the details to an agent.
Automatic Speech Recognition
We also offer ASR (Automatic Speech Recognition) for phone payments. Customers who feel more comfortable speaking their card details or cannot use their telephone keypad are given the choice. ASR helps with adherence to the Equality Act (formerly the Disabilities Act) by providing an accessible service whilst preventing card details from entering the contact centre environment. This ASR functionality maintains all the PCI DSS compliance benefits of keypad data entry.
