DTMF suppression masks those audible beeps customers hear when entering card details over the phone. It is a simple solution that solves a real problem: customers worry about people nearby overhearing their payment information. With DTMF suppression, those tones disappear completely, so customers can pay confidently during phone calls. Perfect for MOTO payment processing (Mail Order/Telephone Order) where agents stay on the line while customers enter payment details securely.
Watch how DTMF suppression masks card entry tones for complete security
When customers press keys on their phone during payment entry, those tones normally travel through the call. DTMF suppression stops that from happening. The technology masks the tones completely, so agents cannot hear them, recordings do not capture them, and anyone nearby stays in the dark. It is particularly valuable for MOTO payments where you need that agent-customer interaction but want zero risk of card data exposure.

Eliminate audible card entry tones to protect sensitive information from being overheard by anyone nearby.
Create a more professional and trustworthy payment experience that builds confidence in your brand.
Integrates seamlessly with your existing phone systems and IVR infrastructure without disrupting operations.
DTMF Suppression delivers immediate business value by eliminating customer privacy concerns while maintaining full agent interaction, leading to higher conversion rates and improved customer satisfaction.
Every time a customer hesitates to give card details because they are worried about being overheard, you lose revenue. Every time an agent cannot help during payment because of security concerns, you lose customer satisfaction. DTMF Suppression eliminates both problems while maintaining the personal touch your customers expect.
When customers feel secure and can still get agent support, they complete more transactions. Fewer abandoned calls mean more revenue and better customer experience.
Significantly reduce your PCI DSS compliance scope since card data is masked and not audibly transmitted. Lower compliance costs and audit requirements while maintaining security.

DTMF suppression is a technology that masks the audible tones generated when customers press keys on their phone during payment entry while keeping the agent connected to the customer throughout the call. This prevents sensitive card information from being heard by anyone nearby while allowing agents to answer questions and provide support during the payment process. Our system uses advanced tone masking technology that completely eliminates the risk of card data being overheard while maintaining full agent interaction.
By implementing DTMF suppression, your organisation can significantly reduce its PCI DSS compliance scope. Since card data is masked and not audibly transmitted, the risk of data interception is eliminated. This allows you to classify your agent-assisted payment system as a lower-risk environment, potentially reducing compliance costs and audit requirements while maintaining the same level of security and customer interaction.

PCI compliance costs are unpredictable and keep changing. With DTMF Suppression, you get a fixed, budgetable cost with Paytia versus the unknown cost of trying to meet constantly changing card security compliance requirements. You significantly reduce your PCI scope since card data is masked and not audibly transmitted, lowering your compliance costs and audit requirements.
With the amount of fraud and scams happening, customers are increasingly concerned about privacy. They worry about colleagues, family members, or people in public spaces overhearing their card details. This privacy concern leads to abandoned transactions, delayed payments, and lost revenue. DTMF Suppression eliminates these concerns by masking all keypad tones.
Without addressing customer privacy concerns, you face higher abandonment rates, lower conversion rates, and reduced customer trust. Customers will find excuses to pay later, choose competitors who make them feel more secure, or avoid phone payments entirely. Every abandoned transaction represents lost revenue and every customer who feels uncomfortable represents a damaged relationship.
Yes, DTMF suppression is ideal for MOTO payment processing (Mail Order/Telephone Order). It enables secure card-not-present transactions over the phone by masking audible tones during payment entry, ensuring PCI DSS compliance while maintaining agent-customer interaction throughout the call.
DTMF suppression helps MOTO payment compliance by eliminating audible transmission of card data. Since card details are masked and not heard by agents or recorded in call recordings, businesses can significantly reduce their PCI DSS compliance scope for MOTO payment processing, lowering compliance costs and audit requirements.
