Guaranteed Successful OTP delivery. Track OTP delivery and usage in real time. Never Guess If Your Customers Got An OTP Or Not, Know For Sure With PressOne Voice OTP.
Here are the reasons your current OTP service is failing
You are not 100% certain if customers receive an OTP or not. You need a service you can track, especially for critical transactions like wire transfers, insurance, and loans.
Delays in receiving OTPs lead to customer frustration and drop-offs. This can harm your reputation and cause customers to doubt your reliability.
Text messages can be intercepted by scammers, putting your customers’ data at risk. Your customers are vulnerable to fraud and security breaches.
Other OTP delivery services, like SMS and WhatsApp, charge you whether or not customers receive or use the OTP.
With PressOne Voice OTP, human interaction is required to obtain the OTP, meaning the customer must answer the call for it to be recorded as delivered. This ensures 100% accuracy in tracking data.
Unlike SMS and WhatsApp OTP services, which charge you regardless of delivery and use, PressOne Voice OTP only bills you for answered calls, resulting in significant cost savings. You can also control the length of the voice OTP.
With delivery rates up to 99%, PressOne Voice OTP is suitable for all customers with a phone, unlike the Email OTP service, which is only popular among certain categories of customers.
Relying on personal lines often results in uneven service quality, which can damage your business reputation and undermine customer trust.
Never guess if your customers got an OTP or not, know for sure with PressOne Voice OTP.
