Incoming Verification...
Processing Voice Call
SMS OTPs often get blocked by "Do Not Disturb" (DND) settings. Voice calls bypass these filters to ensure every user gets verified.
Perfect for elderly users or those with visual impairments. Automated voices read out the OTP clearly for better accessibility.
Voice OTPs are harder to intercept than text messages, providing an extra layer of security for high-value transactions.
Your app sends a request to InfoTek's API with the user's phone number.
Our system generates a unique 4-6 digit code and initiates a call.
The user receives a call, and the automated voice reads the code twice.
The user enters the code into your app, and access is granted instantly.
