Capabilities · Reusable identity
Verify people your business already knows — against your own records — before any external check is made.
The problem
External identity checks aren't getting cheaper in South Africa. Most of the customers being re-verified are ones your business already knows.
Every external verification pushes another fee through your P&L — even for customers you've onboarded before.
Different divisions hold the same customer's verified records — without being able to legally reuse them.
Reusable capability
Biometric reauthentication matches returning customers against your own verified records — external checks only run when there's no match.
Process
Four steps. The first three keep the verification inside your environment. The fourth runs only when there's no internal match.
A face and ID number arrive through the same API as any standard verification.
The platform searches your enterprise's stored records and matches face to ID in real time.
On a match, identity is confirmed inside your own environment. No external fee, no friction.
No match means the external check runs once — and that customer is enrolled for next time.
The questions enterprise teams typically ask before taking reauthentication into production.
No. Reauthentication requires a biometric match alongside the ID number — the face presented now must match the face tied to that ID in your records. A pure lookup isn't defensible. Biometric anchoring is what makes the reuse trustworthy.
Reauthentication is internal identity verification: it runs inside a single enterprise's own customer pool, so no data leaves your organisation. Reusing records across your own divisions is legally distinct from sharing data between separate companies.
The platform escalates the verification to the relevant external source — the same way you'd run it today. That customer is then enrolled into your reauthentication pool, so future checks find them internally.
No. Reauthentication sits in front of it. First-time verifications still flow through your standard process. What changes is ongoing customer reauthentication — the second, third, hundredth interaction with the same person.
High-volume, multi-channel enterprises where the same customer touches the business repeatedly — telcos, financial services, insurance, and retail. The deeper your verified customer base, the more reauthentication earns its place.
Annual licensing per unique identity managed, plus pass-through fees for the external checks that still run. As your verified pool grows, fewer external checks are needed — and the cost line that scales with volume gets quieter.
