RD Service Registration remove caching of all kinds.

Registered devices handle the issue of eliminating the usage of stored biometrics. Unlike a public device, the RD Service converts your biometric device, such as a fingerprint or iris scanner, into an L0 Registered Device. This ensures that all parties involved in Aadhaar transactions have a secure communication channel. 

The Registered Device (RD) Service prioritises security by providing safe device registration without storing any data on the device. Compared to public devices, registered devices have three main advantages:

Device identification: Each device is given a distinct identifier, enabling fraud management, security analytics, and traceability.

Eliminating the use of stored biometrics: For security, biometric data is collected on the device using the provider key. Before reconnecting to the host application, the Registered Device (RD) Service of the device provider prepares an encrypted PID block to guard against data breaches.

Certified Registration: The device can be registered with UIDAI using the RD Service in a secure and authorised manner (Aadhaar). It includes biometric capture, any user interactions during capture (including preview), signing in, and biometric encryption.

For a faster registration procedure, RD Service provides UIDAI certification to the device that supports end-to-end security at all levels from sign-in to biometric capture (user preview) and data encryption.
