How fraud detection step-up verification works
Your app requests a customer’s numberWhen setting up an account — or, as part of a high-value transaction — your app asks your customer to enter his/her phone number.
Your app sends the number to Number InsightNumber Insight returns real-time intelligence on the phone number — whether it is valid, reachable, a virtual number or a landline and more. If the number is unreachable or invalid, your app can ask the customer to re-enter their mobile number.
Your risk scoring engine raises possible alertsIf the information returned by Number Insight raises alerts in your risk scoring system, your application can trigger an additional authentication step using Vonage APIs Verify.
