Security and Resilience

Contingency Mechanism: Implementation of automatic redundancy for liveness providers. In the event of an instability, the SDK switches providers to ensure a seamless capture journey.
Liveness Engine Optimization: Technical updates to improve liveness providers resulting in a lighter and more efficient SDK.
Device Protection: Updated protection layers against external threats and hardware integrity validation.

User Experience

Brand Positioning: Support for displaying the Unico logo during the capture flow via our proprietary engine, reinforcing trust and visual identity throughout the journey.

If you encounter any issues during the capture flow after this update, please contact our support at https://empresas.unico.io/hc/en-us.

As of April 28, 2026, only apps built with iOS 26 will be accepted by the App Store. Unico will align its development with iOS 26 in a future version of the Unico Check iOS SDK. (Source)

To ensure the continuous evolution and security of our solutions, Unico informs that support for iOS 12 will be discontinued in a future version of the Unico Check iOS SDK. With this change, the minimum supported version will become iOS 13.
