MATTR GO Hold device requirements

Operating

The following operating systems and versions are supported:

• iOS 15 or higher.
• Android 7 or higher.

Regardless of the minimum required version, ensure that your users upgrade their devices to the latest operating system version for optimal performance.

User Settings

User settings can affect app performance. This includes, but may not be limited to, the following list:

• Enabling camera access: Device camera is required in many issuance and verification flows. Failing to provide the app with camera access will prevent using these flows.
• Enabling biometrics: Access to the app can be configured to use biometrics authentication. Failing to enable biometrics will prevent using this functionality.
• Notifications settings: The app can notify users when certain events occur (e.g. a new credential is available). Disabling app notifications will prevent the app from sending these notifications, and users will only discover them when they open the app.
• Different font scaling: May affect adherence with accessibility standards.

Connectivity and settings

Some app features require access to the public internet, using relatively low data. However, larger credentials with images may be up to 2MB in size. Sources such as JSON-LD schemas and various MATTR VII tenant metadata may be fetched as required and cached.
