Time and attendance system suitable for large or mobile work forces

A system comprising:

• a first computing device, including a power source, that is associated with a first employee and that collects employee specific (ES) data, and which transmits the ES data that is collected, wherein the ES data collected by the first computing device is incrementally stored in an offline employment activity reservoir configured to reduce power consumption of the power source of the first computing device during collection and transmission of the ES data;
• a second computing device, including a power source, that is associated with a second employee and that collects ES data and which transmits the ES data that is collected, wherein the ES data collected by the second computing device is incrementally stored in the offline employment activity reservoir to reduce power consumption of the power source of the second computing device during collection and transmission of the ES data;
• and
• a server configured to:
• define a geofence configured to be allocated to a worksite associated with the first employee and the second employee;
• receive ES data collected by the first computing device and ES data collected by the second computing device, wherein the ES data collected by the first computing device and ES data collected by the second computing device each include at least haptic data collected by the first and second computing devices;
• verify an identity of the first employee based on the ES data collected by the first computing device;
• subsequent to verifying the identity of the first employee, determine whether the first computing device is in the possession of the first employee based on the ES data collected by the first computing device and comparing it to ES data collected by the second computing device;
• and
• generate a notification at an employer side user interface in response to the server determining that the first computing device is not in possession of the first employee.

A wearable device comprising:

• a processor, a power source, and supporting circuitry configured to:
• collect a plurality of employee specific (ES) data associated with a first employee in possession of the wearable device;
• transmit, to a server communicatively coupled to the wearable device, the plurality of employee specific (ES) data associated with the first employee, wherein the plurality of ES data includes at least haptic data;
• receive, from the server, an indicator that the first employee is within a geofence defined by the server;
• receive, from the server, a verification of the identity of the first employee based on the plurality of ES data;
• wherein the plurality of ES data is incrementally stored in an offline employment activity reservoir configured to reduce power consumption of the power source during collection and transmission of the plurality of ES data;
• and
• receive, from the server, a determination that the first employee is not in possession of the wearable device based on the plurality of ES data.
