An electronic lock controller comprises a trusted time provider, a near field communication transceiver, and a logic processor. The trusted time provider provides a trusted time value. The near field communication transceiver receives power and a digital credential from an operator-side interface device. The logic processor produces an open or close command for an electromechanical lock based on the trusted time value and the digital credential. The electronic lock controller is powered solely by the near field communication transceiver.
