Abstract: A method and device for using biometric data captured at the time of check-in and check-out by an agency employee worker at a client designated location to verify the identity and location of the worker at the time of check-in/out includes the worker opening an application software on a mobile device and clicking a “Check-In” button in an application display to perform a check-in process defining a biometric capture identifying the worker. The biometric capture includes by a photo, a fingerprint, a retinal scan, or a worker DNA upon arriving at a work location. The worker accepts the captured data from the first check-in stage as accurate. The worker performs a check-out process at a worker finish time including in a first finish stage opening the application software and clicking a “Check Out” button in the display. In a second finish stage the biometric capture identifying the worker is repeated.
