Missed-Call Verification

Touch-free missed-call phone number verification

Blink is the most recent addition to our Conversion Rate Optimization Suite. This phone number verification technology utilizes our missed-call verification API, and it eliminates the need for human interaction during verification, resulting in a great user experience while also removing the possibility of human error. Yes, some users do enter the one-time password (OTP) incorrectly!

Blink is an SDK that can be integrated into your mobile app. It works by placing a call to the phone through our missed-call verification API, intercepting this call and verifying the phone number with the API before the user has time to even answer the call. This results in a swift and smooth phone number verification process with the end user just seeing a missed call on their phone.

Blink is currently only available to Android users.

Enough reading, check out our demo video of Blink's missed-call verification here! Should the end user's phone not be able to be verified by Blink, RingCaptcha proceeds to verify the phone number by SMS and then voice OTP.

How do I add missed-call verification to my verification process?

We recommend using our Android SDK as Blink is already built into the SDK. You can check out the other advantages of using our SDKs in the next section below.

If you wish to use Blink without using our SDK, you can call our missed-call verification API directly. Write to our support team through our live chat.

Advantages of using our SDKs

Our SDKs have all of our best features and best practices already built in!
Some of the pain points they address:

Incorrect OTP input
- Our touch-free verification (Android only) utilizes ‘missed-call’ technology for phone verification eliminating the need for any user action
Poor OTP deliverability
- Our SDKs request OTP through RingCaptcha’s true single OTP API endpoint that routes OTP over different routes/medium during route disruptions
Users getting distracted while waiting for OTP
- Our SDKs are set up to send follow-up OTP for phone numbers that have not converted after 60 seconds
User not receiving OTP for other reasons. For example, phone number is blacklisted.
- A ‘Call for Help’ button that sends a request to support team
- Our SDKs can trigger our AI-assist feature which dials out to unconverted phone numbers to automatically determine why the user did no convert
