Check your Biomatric Status

With the use of the Sahel pp. unified government application, the Ministry of Interior has launched a service for verifying the biometric completion statute.
He announced the launch of a new service that will assist individuals in determining if they have completed or still need to perform biometric fingerprinting. He also mentioned that the service can be accessed via the application’s “Security service” section.
Pen your Sahel app and select the “Service” section at the bottom to view your biometric status. (The bottom bar’s second button from the right).
