Biometric attendance tracking system and method using mobile devices

摘要

Aspects of the disclosure provide a host mobile device for tracking attendance of a plurality of attendees each operating an attendee mobile device. The host mobile device includes a processor configured to execute program instructions, and a memory configured to store program instructions for causing the processor to receive an access request including attendee identification information of an attendee from an attendee mobile device, determine whether a first set of access conditions are satisfied in response to the access request, and allow the attendee mobile device to submit biometric information of an attendee to the host mobile device when the set of access conditions are satisfied. The first set of access conditions includes whether an operation distance between the host mobile device and the attendee mobile device is shorter than a preconfigured threshold distance defining a border of an area for a session attendees have registered for.
