A robust user verification service is required in many websites and apps today, especially if they are related to ecommerce or banking. The ability of an app to swiftly and efficiently verify the identities and transactions of the user not only supports improved customer satisfaction and retention, but also cuts down the risks associated with data security and phishing attacks. While typical SMS OTPs have been used for this purpose for quite a long time, today many companies are also leveraging Voice Solutions for this process. Using voice OTPs as an added channel for user verification cuts down the risks of data leakage and fraud.
Voice OTP Verification basically takes plane through a phone call made to the registered phone number of the user. The user answers the phone, listens to the relevant OTP digit played over the phone call, and subsequently enters the OTP in the app interface to verify a transaction or a login. There is no internet access required to receive the OTP.
Multiple Voice OTPs can be sent in a parallel manner to multiple customers, so as to reduce the waiting time involved. This system helps in verifying transactions quite promptly, as voice OTPs are usually delivered within seconds.
Powerful Voice API can be used by brands to deliver OTPs to networks across the globe, with the best possible delivery rates and speed. By using such API, you will not have to worry about the location of your customers, as this service makes sure that the OTP will reach them in time, regardless of the physical distance involved.
