What Does the Duplicate Feature Do?

The Duplicate Check helps prevent fraud by detecting if the same person tries to register multiple times. It compares a new customer’s face against your existing database of completed verifications.

Why It Matters

The feature instantly helps you:
  • Stop Bonus Abuse – blocks the same person from repeatedly claiming “new user” promotions.
  • Identify Fraud Rings – detects individuals using many different stolen or fake IDs.
  • Block Banned Users – prevents fraudsters who were rejected from re-registering.

How It Works

  • Separate checks – Face and Document Face are checked independently. You can run duplicates on the selfie, document photo, or both.
  • Automatic check – Every time you perform a verification, the system runs a duplicate check.
Good to know
  • If you use the same clientId for the same user, the Duplicate feature will not add a tag - we assume you’re making a re-verification

Possible Outcomes

  1. No match found → Verification is approved as usual.
  2. Match found → The user is marked as Approved (Suspected).
  • The verification is still valid since all submitted data is correct.
  • You decide whether to onboard or deny the customer.
  1. Verification denied for other reasons → Duplicate check is not performed.
