Abstract: A method for recording attendance using BLUETOOTH-enabled mobile devices comprising the steps in the sequence set forth: triggering (104, 105), by a logged-in user, a respective mobile device to detect for surrounding BLUETOOTH beacons, wherein different user account each is assigned with their respective list of BLUETOOTH beacons for triggering the attendance recording; comparing (106), by the respective mobile device, the detected list of BLUETOOTH beacons with the assigned list of BLUETOOTH beacons of the corresponding user account and only retrieves one or more BLUETOOTH beacon IDs from BLUETOOTH beacons that are assigned to the corresponding user account; and forwarding (107), by the respective mobile device, the retrieved BLUETOOTH beacon ID(s) together with a retrieval timestamp to an administrator server for generating an attendance record.

Abstract: A system for collecting and transferring electronic information includes one or more servers, having one or more centralized databases for storing or retrieving the data, connected to a network, one or more computing devices connected to the servers via the network for retrieving the data from the centralized databases, and a plurality of biometric devices connected to the servers via the network, located at different locations. Each biometric device comprises a system for identifying users based on biometric data of the users, a system for storing the biometric data and activity information of the users, and a system for sending the biometric data and activity information to the servers, in communication with the servers in real time via the network.
