In the platform architecture. the Engine acts as a centralizer of the existing flows. Users send requests to the Engine through the application or accessing directly a communication provider. In turn, the Engine communicates with Biometric Suppliers to make the services available to users.

Within the biometrics engine, the lambda functions will route the biometrics credentials to an appropriate biometrics’ supplier. If a voice recording is received, for example, the engine will select a biometric supplier which is capable of performing voice authentication. The biometric supplier selection may be guided by the user’s selection within the mobile app.
