Some embodiments include a kit for forming a radio frequency container. The kit may include a top panel, a bottom panel having a raised support, at least one side panel configured to connect the top panel and the bottom panel, and an RF antenna configured for attachment to an interior surface of the container. The top panel, the bottom panel, and the at least one side panel may be configured to reflect and contain RF signals within the radio frequency container.

A card comprises an antenna configured to generate and receive radio frequency signals, a chip coupled with the antenna, the chip configured to store sensitive information and communicate the information to an authorized reader via the antenna, and a switching mechanism configured to tune and detune the antenna relative to the chip to enable and disable respectively, the chips ability to communicate the sensitive information via the antenna.

A kit and method for improving the security of a card reader having a plurality of wafers for insertion individually into the card reader via a card slot in the card reader, where each wafer is shaped and sized so that the wafer can be inserted through the card slot in an insertion direction and positioned in a cavity in the card reader. The plurality of wafers are configured to couple together when inside the cavity to form a stack of wafers.

An RFID reading enclosure having a Faraday cage including a cage floor and a cage hood hinged to the cage floor. The cage hood includes a RF blocking fabric formed on a frame with the interior of the Faraday cage having a volume between 4.5 and 30 ft.sup.3. There are at least two RFID antennas positioned to transmit signals into the Faraday cage, with the two RFID antennas having a transmission axis along different orientations.

Disclosed is a technique for prevention of false tamper positives experienced by an electronic device by use of a custom profile. The technique includes application of sensors of the device to collect data from the environment. Further, the device determines whether an event causes accidental triggering of tamper response as the environmental data varies. Accordingly, the conditions triggering a tamper response are dynamically changed as the environmental data changes.
