Abstract: A smartcard device which includes power harvesting. Power is stored. That stored power is used to obtain biometric information on the card. In an embodiment, a smartcard is used in a card reading device, e.g, an ATM machine or other payment device. In one embodiment, the ATM swallows the card completely. In another embodiment, the card can be partly inserted into the machine or read and powered wirelessly. The fingerprint reader is put on the smart card. The client inserts the smart card into a standard ATM. The ATM recognizes a smart card with fingerprint authentication, harvests power and returns the smart card to the user. The Client authenticates their fingerprint using a fingerprint reader powered by harvested power then re-inserts the smart card. If authenticated, the client is prompted to choose one of the menu options.

Abstract: A target device for use with a switch device of a proximity switch has a wireless receiver means (6) for detecting and receiving a first pulsating signal (A) with a first carrier frequency (f1) from a nearby transmitter module (5), demodulating (6, 7) the received signal, and if a superimposed digital signal is present, inverting (9, 10, C4, and Q1) the superimposed received digital signal or, if the superimposed digital signal is absent, passing the existing energy through (10). The target device also has a wireless transmitter means (12) for modulating and sending the inverted pulse train if this exists by the second carrier frequency (f2) to the receiver switch unit (13). Additionally, the target comprises functionality to transmit the carrier frequency (f2) continuous and unmodulated where a continuous and unmodulated carrier frequency (f1) is present. However, upon existence of the pulsating signal only one of the receiver (6) and the transmitter (12) receives or transmits a signal at a given time.
