It also means there is no need for the caller to pause the call recording to enter details and the agent can remain on the line the whole time. By preventing any numerical data from entering the environment to begin with, there is no data stored on the server, and also becomes very difficult for any hacker to access information if intercepting a phone call.įrom a PCI compliance perspective, this removes significant risk, as it additionally removes any need for the agent on the other end of the phone to see, hear or store any sensitive data.

Utilising DTMF Masking technology eliminates data breaches in businesses and Contact Centres. Phone payment apps like PayGuard® allow the payer to enter in their card information, then subsequently blocking, muting or manipulating the DTMF signal after it has been received by the application, in order to prevent it from travelling further down the phone line. This is where payment applications that use DTMF masking can really help. The problem with an automated payment line is that the customer experience can be poor, as it is an automated system. This in turn sends DTMF signals to a payment application that processes the payment. Here a customer would type their sensitive card information, such as their long card number, their expiry date and their security code, into the telephone keypad.

Many companies turn to DTMF and use automated payment lines to process phone payments.
