Biometric Roll Call
Read full descriptionHide full description
RollCall turns your iPhone or iPad into an on-device attendance scanner. Enrol people once, start a session, and the app marks them present as they appear - ideal for classrooms, events, and shift teams. Features: Live scanning - Use the device camera to recognise enrolled faces and record attendance in real time. Smart rosters - Group people by class, shift, event, or any list you need. Reports & export - Finish a roll call and share a PDF summary or CSV with status, timestamps, and GPS via Mail, AirDrop, or Messages. Session history - Searchable log of every roll call. Works offline - Scan and save with no internet. Suited to sites, trips, and poor Wi‑Fi. IP cameras - ONVIF discovery and RTSP (including brand stream presets). Main/high-res streams work best for recognition at distance. Privacy: Face detection and matching run only on your device. No face images or biometrics are sent to or stored on our servers. Facial profiles are protected with AES-GCM and kept in the device Keychain. Spend less time on the register. Download RollCall and run attendance on-device, securely.
