A fingerprint sensing system comprising a device connection interface, and a sensing arrangement including sensing structures, a read-out circuitry connected the sensing structures, and a sensing arrangement controller for controlling the sensing arrangement between at least a first sensing arrangement operational mode and a second sensing arrangement operational mode. The system further comprising supply circuitry connected to the sensing arrangement, and comprising a supply circuitry controller for controlling the supply circuitry between a first supply circuitry operational mode and a second supply circuitry operational mode in which modes different supply power is provided to the sensing arrangement. The supply circuitry controller transitions the supply circuitry between its modes in response to a power state signal indicative of a future transition of the sensing arrangement from the first operational mode to the second operational mode.
