Biometric security assembly
First Claim
1. A biometric key comprising a housing and a biometric sensor, a key circuit, and a plurality of electrical contacts connected to the housing wherein:
- the key circuit incorporates a power supply circuit and a communications circuit;
at least two of the plurality of contacts are in electrical communication with the power supply circuit;
the communications circuit is in electrical communication with at least two of the plurality of contacts;
at least two of the plurality of contacts can transmit and receive data, enabling the biometric key to be received in a receptor in a first configuration or a second configuration inverted relative to the first configuration such that the biometric key can be inserted into the receptor in either of the two configurations to provide access to a facility;
wherein the biometric sensor reads biometric data from a key operator;
wherein the receptor has a plurality of mating contacts;
wherein the receptor incorporates a receptor circuit that incorporates a power supply and a communications circuit; and
wherein the communications circuit comprises an arrangement of a plurality of 2-input nand gates and a switch, wherein communication data is electrically communicated to both inputs of a first nand gate, an output of the first nand gate is electrically connected to an input of a second nand gate, both inputs of a third nand gate are electrically connected to a second input of the second nand gate, the output of the second nand gate provides a received data signal and a transmitted data signal is provided to both inputs of the third nand gate.

Abstract
A biometric key (10) having a body or housing (11) incorporating a biometric sensor (17) uses a plurality of contacts (19, 20, 21) enabling the key to gain access to a facility. There is also provided a receptor (25) for receiving the biometric key (10), wherein the biometric key (10) and receptor (24) have contacts (19, 20, 21) and mating contacts (30, 31, 32), respectively, for communicating. The biometric key (10) can communicate biometric data acquired from a key operator to the receptor (25). The biometric key (10) can communicate with the receptor (25) when received in a first orientation and also when received in a second orientation where the contacts (19, 20, 21) are inverted from the first orientation.
