Abstract: A RFID cabinet comprises a cabinet structure and one or more drawers or shelves. Chambers are formed within the cabinet to house the one or more drawers or shelves. An RFID scanner is configured to scan items tagged with RFID tags in the chambers via one or more antennas. The antennas can include transmit and receive antennas or antennas configured to perform both transmit and receive functions. The drawers can have a access cover, or lid that can be controlled so as to control access to the drawer. The scanner can be configured to perform inventory control for the tagged items.

Abstract: RFID tags are used for many purpose including tracking RFID interrogators are used to retrieve information from tags. In many applications, RFID interrogators and RFID tags remain stationary during interrogation. Regions of low energy due to interference from either additional antenna or reflections from RFID tags and objects can impede or prohibit the reading of RFID tags residing in such regions. Stirring of the generated electromagnetic field is a method of moving around the regions of low energy, where tags can not be read, during the interrogation process. Mechanical stirring is accomplished by introducing a conductor into the electromagnetic field and moving it about in the field. Solid state stirring is accomplished by introducing a variable conductor into the field and varying the conductivity of the variable conductor. Mathematical stirring is accomplished by use of a plurality of antenna and controlling the phase difference between the antenna in a configuration known as phased antenna arrays.

Abstract: A method for authenticating a document comprises obtaining the contents of a document, obtaining biometric characteristics from an individual, forming a message based on the contents of the document and the biometric characteristics of the individual, generating a digital signature based on the message and a key, and writing the digital signature to an Radio Frequency Identification (RFID) tag affixed to the document.
Abstract: Systems and methods for an RF nulling scheme are provided. An RF nulling scheme can minimize the level of unwanted RF signal reflections entering the receiver without attenuating the desired signal response from an RFID tag. In one aspect of the RF nulling scheme a synthesizer signal can be split between a main path and a nulling path. In the nulling path the signal from the splitter can be routed through an electronically variable phase shifter and variable gain amplifier to create a nulling signal. The nulling signal can cancel the unwanted reflected signal. The phase or amplitude of the nulling signal can then be adjusted to improve cancellation as necessary.
