What is PCI?

The Payment Card Industry Data Security Standard (PCI DSS) ensures that all card payments are processed securely to protect sensitive data and ultimately reduce fraud. Companies that accept, handle, store or transmit credit card details need to comply with the security standards, irrespective of their size or the volume of transactions processed.


How does it work?

Rather than reading out the card number and security code when making a payment over the phone, your customers simply have to enter the digits via the telephone keypad. Contact with the call centre agent is maintained throughout, but all tones are muted, so information remains shielded. Payment details are then forwarded straight through to the merchant’s credit card processing platform in a secure format such as XML over HTTPs.

For automated payments, customers call the payment line and their calls are delivered straight to the Callstream Vault platform where again they enter their credit card details for secure processing.
