# Voice

> Turn a live phone call into a PCI-compliant card charge from a single call transfer

Turn a phone call into a PCI-compliant payment. Use Voice to collect card information and other payments over the phone, all from a single call transfer.

## Technology for voice agents

**PCI compliant**: Transfer your call to Natural to keep your system completely out of PCI scope.

**Capture spoken card details**: Natural can handle DTMF and spoken card details.

**Tokenized card credentials**: Natural tokenizes the card information and stores that payment credentials for you.
