✨ Features

📱 Platform Behavior

Android

• FaceRD is launched via intent
• Encrypted PID may be returned to the app
• App can proceed immediately after capture

iOS (Important)

• FaceRD runs in headless mode
• Face capture & PID generation happen inside FaceRD app
• PID is sent directly to backend using callbackUrl
• App does not reliably receive PID
• User must manually return to the app
• App should poll backend using txnId

This behavior is mandated by UIDAI and Apple security policies.

📘 For detailed iOS behavior, see:
