Pega Mobile Client supports leveraging various mobile device features to enhance app functionality and user experience. Barcode scanning (A) is commonly used in logistics and retail applications for quick identification and tracking of items. Biometric identification (C), such as fingerprint or facial recognition, adds an extra layer of security for user authentication. Push notifications (D) are crucial for real-time communication, alerting users to updates or required actions within the app, even when the app is not actively in use.References: Pega Community documentation on Pega Mobile Client capabilities.
