Browser APIs

Webview compatibility

The SDK supports the following webviews:

Webview Name iOS Android
Facebook Yes Yes
Instagram Yes Yes
WKWebView native iOS webview Yes -
SFSafariViewController native iOS webview Yes -
Android WebView native Android webview - Yes
Chrome Custom Tabs native Android webview - Yes
Trusted Web Activity native Android webview - Yes

The SDK is compatible with Meta webviews, i.e. you can run it in Facebook and Instagram apps for Android and iOS. We also support native webviews for iOS and Android. However, we do not guarantee full compatibility or functionality with webviews from applications built using other frameworks, including hybrid frameworks, the performance and behaviour may vary.

Minimum supported devices version

Devices Minimum version
Android Android 10

Veridas recommends the following minimum requirements:

Android devices Minimum recommended requirement
Camera resolution At least 1080p (Full HD)
RAM At least 4GB, 6GB preferred
Processor (CPU) Mid-range and recent
Screen resolution At least 1080p (Full HD)
iOS devices Minimum recommended requirement
Device model From iPhone 11 onwards

Please note that devices below these minimums may not function properly. Additionally, it's important to emphasize that while meeting these minimum specifications ensures functionality, exceeding them does not guarantee impeccable performance in all cases.

Video recording parameters

During the Selfie flow (including the active liveness/SAP mode), the SDK records video with the following parameters:

Parameter Value
Requested resolution 1920x1080 (Full HD)
Requested frame rate 30 fps
Video codec VP9 (video/mp4;codecs=vp9) on desktop and Android; H.264 (video/mp4;codecs=avc1.42E01E) on iOS
Video bitrate 1.5 Mbps (1,500,000 bps)

The resolution and frame rate above are the values requested from the camera; the browser negotiates the closest value the device can deliver. The Selfie SDK does not record audio.

Image capture parameters

During the Selfie flow (both passive and active/SAP liveness), the SDK captures the evidence image (image) with the following parameters:

Parameter Value
Requested camera resolution 1920x1080 (Full HD)
Captured resolution Native resolution negotiated by the browser for the camera stream (up to 1920x1080); no cropping or resizing is applied
Image format JPEG
JPEG quality 1 (maximum, no additional compression)

The resolution above is the value requested from the camera; the browser negotiates the closest value the device can deliver.
