In various embodiments, a circuit arrangement is provided, including a first antenna tuned to a first frequency range, a second antenna tuned to a second frequency range being different from the first frequency range, a controller coupled to the first antenna and the second antenna, wherein the controller is configured to receive its operational power via at least one of the first antenna and the second antenna, and a deactivating structure configured to deactivate the communication of the controller via the second antenna upon reception of electromagnetic waves with the first frequency range via the first antenna.

A radio tag capable of indicating to a reader, via a wireless link, that a variation in energy has crossed a predetermined threshold, this variation in energy being chosen from the group made up of a variation in the temperature of the radio tag and a variation in the magnetic field in which the radio tag is immersed. This radio tag includes transducer material chosen from a group made up of a thermal shape-memory material, a magnetostrictive material and a magnetic shape-memory material. This transducer material is deposited and affixed without any degree of freedom onto a substrate or an antenna of the radio tag to form, with the substrate or the antenna, a multilayer structure which flexurally deforms the antenna between a bent conformation and a less bent conformation when the energy variation crosses the predetermined threshold.

An apparatus that identifies an object includes a frequency detector (112) that detects a frequency over which an RFID tag (102) communicates, and an object identifier (120) that identifies the object based at least in part upon the detected frequency. The frequency detector may detect a plurality of frequencies over which a plurality of RFID tags transmit information. The apparatus also optionally includes a frequency pattern generator that generates a frequency pattern that is indicative of an identity of the object, wherein the object identifier compares the generated frequency pattern with known frequency patterns to determine the identity of the object.

In accordance with various embodiments, a radio communication processor arrangement including a chip and a battery integrated into the chip is provided.

Provided is a smart card that can prevent malfunction in the smart card and improve stability of radio frequency communication by removing interference of an AC signal generated at the antenna terminal of the smart card. The smart card includes: a dual antenna configured of a first antenna and a second antenna for performing radio frequency communication with a card reader; an IC chip electrically connected to the first antenna to perform radio frequency communication through the first antenna; a power generation unit for generating DC power by converting a radio frequency signal received through the second antenna; a control unit for receiving the DC power generated from the power generation unit to control various modules; and a cut-off unit arranged between the first antenna and the IC chip to cut off a radio frequency signal received through the first antenna under the control of the control unit.

A device includes a first inductor and a second inductor. The first inductor has a first inductive coupling profile. A first circuit component is coupled to the first inductor. A second inductor has a second inductive coupling profile. A second circuit component coupled to the second inductor.

Typically, online payments require entering sensitive transaction information into a third-party web browser or application. This may expose sensitive transaction information to an increased risk of inadvertent disclosure. Apparatus and methods are provided for a smart card which enables users to securely complete online payments without entering any sensitive transaction information into a third-party system. The smart card may include a touch-sensitive screen configured to display selectable payment options. The smart card may include a microprocessor and wireless interface. The wireless interface may provide wireless communication capabilities and the ability to initiate online payments based on information captured by the touch-sensitive screen.

Various embodiments of the present disclosure identify radio frequency identification tag(s) and/or location(s) thereof. Embodiments may perform such identification utilizing any number of antennas configured at various power levels and/or frequency channels, such as by incrementing and/or decrementing the power level of each antenna and measuring a number of tag reads at interval for each antenna. Confidence scores for each antenna may be generated and compared. Some example embodiments initiate an interrogation command associated with a RFID tag, cause activation of a plurality of antennas at a plurality of transmit power levels, identify a count of tag reads associated with each antenna, and determine a tag location associated with the RFID tag based on the count of tag reads for each antenna.

A radio frequency identification (RFID) switch tag is disclosed. This RFID switch tag includes a base component having an ultra-high frequency (UHF) booster, and a detachable component having at least one UHF RFID module and a high frequency (HF) RFID module. In some embodiments, the detachable component is positioned in close proximity to the base component in a first configuration of the RFID switch tag such that the at least one UHF RFID module is sufficiently coupled to the UHF booster in the base component to form an UHF RFID system having a desired performance. The detachable component can also be separated from the base component to obtain a second configuration of the RFID switch tag, and the HF RFID module remains functional within the detached detachable component so that the detachable component can be used as a standalone HF RFID tag.

Method, container corner lock and system for fastening a first container corner casting of a first container and a corresponding second container corner casting of a second container. The first container is stacked on the second container. The container corner lock includes: a first protruding part; including a first locking for fixing the first protruding part into the first recess; a second protruding part, including a second locking for fixing the second protruding part into the second recess; an electric motor configured to block or unblock the movement of at least one of the locking means; a first wireless transceiver; a processing circuit configured to receive the signal from the wireless transceiver and generate a command for operating the electric motor and a second wireless transceiver or transponder with a shorter range than said first wireless transceiver.
