Improved RFID devices and manufacturing methods that utilize more efficient RFID designs, result in less manufacturing material waste and increased recycling opportunities, all without sacrificing RFID device performance, are disclosed herein. Some exemplary embodiments of the improved RFID device may make use of a thinner foil, a hollowed-out foil, a “no-strip” design, or a tessellated design that may reduce material usage. Other exemplary embodiments may use a lower-impact and/or biodegradable adhesive so as to improve aluminum recycling and lessen risks to the environment.

A tire fitted with a transponder comprises: a crown comprising a crown reinforcement having an axial end at each of its edges, connected at each of its axial ends by a sidewall to a bead having an interior end; a carcass reinforcement, formed of adjacent first threads, which is anchored in each bead around a spiral formed by second threads; and the transponder comprising a dipole antenna consisting of a spring defined by a pitch P and a diameter D. A ratio between the pitch (P1) and the diameter (D1) for a loop of a first region of the spring is greater than 0.8, and the transponder is situated axially on the outside of an interior end of the bead and radially between the upper end of the spiral and the axial end of the crown reinforcement.

Wireless power may be transferred between systems that are magnetically coupled in reactive near-field proximity. A magnetic field between a first antenna and a second antenna are coupled. The first and second antenna are (i) resonant at an operating frequency, and (ii) located within reactive near-field proximity. The reactive near field proximity represents a region that is less than a distance of 0.159 of the free space wavelength for the operating frequency. The wireless power provides a receiving system with a threshold amount of wireless inductive power exceeding 1 watt. Each of the first and second antennas have a spherical volume with a diameter less than 1/20 of the free space wavelength of the operating frequency and the energy dissipated to far-field radiation, per cycle, due to circulating currents from the first antenna is less than ½ the peak energy stored in the magnetic field.

A mounting base for use with a wirelessly locatable tag may include a base portion defining a latching member configured to engage a wirelessly locatable tag to releasably retain the wirelessly locatable tag to the mounting base, a contact block attached to the base portion and configured to be positioned at least partially within a battery cavity of the wirelessly locatable tag, the contact block defining a top side and a peripheral side. The mounting base may further include a first conductive member positioned along the peripheral side of the contact block and configured to contact a first battery contact in the battery cavity of the wirelessly locatable tag, a second conductive member outwardly biased from the top side of the contact block, the second conductive member configured to contact a second battery contact in the battery cavity of the tag, and a power cable coupled to the base portion.

There is provided an antenna device, a control method, and a program that control enabling or disabling of a plurality of IC card antennas by using a mobile terminal. The antenna device includes: a mobile terminal antenna that receives a radio wave output by a reader/writer provided in a mobile terminal; a plurality of IC card antennas that communicates with an IC card including an IC chip for the IC card that reads/writes data in a contactless manner in response to a command transmitted by the reader/writer; and a control circuit that operates by using power generated when the mobile terminal antenna receives the radio wave output by the reader/writer and controls enabling or disabling of each of the IC card antennas in response to the command transmitted by the reader/writer. The present technology is applicable to a playmat used for a card game using a smartphone having an NFC function and an IC card.

The present invention relates to card-type information substrates, such as payment cards, in which a frame is implemented so as to impart increased weight and/or superior appearance to the card-type substrates, wherein the influence of the frame on the RF performance of the card-type substrate is taken into consideration. For example, in illustrative embodiments the influence of a conductive material in the frame is reduced by selecting one or more appropriate features countering the negative effect on the RF performance.

A system is provided for integrating conformal electronics devices into apparel. The system includes a flexible substrate onto which a flexible device is disposed. The flexible device can include a stretchable coil that can be used to receive and transmit near field communications. The flexible device also includes an integrated circuit component and a memory unit. In some examples, the device also includes a sensor that is configured to record measurement of the wearer of the apparel and/or the surrounding environment.

A wearable payment device, such as a finger ring worn by a user, communicates payment data to a payment reader that uses the payment data in order to request a payment transaction. Such wearable payment device may be conveniently carried by and accessible to the user such that utilization of the payment device for the payment transaction is less burdensome for the user, thereby encouraging use of the payment device for payments. Indeed, in some cases, such as when the payment device is implemented as a finger ring or other type of jewelry, the user may be encouraged to carry the payment device in an exposed manner such that it is readily available for the payment transaction without the user having to search in a wallet, pocket, or purse.

An RFIC device including a resin block having a first surface, a second surface that faces the first surface, and a through-hole that extends through the first surface and the second surface. Moreover, the RFIC device includes an RFIC element that is embedded in the resin block and a coil antenna disposed in the resin block that is connected with the RFIC element and that has a central axis that extends from the first surface to the second surface. In addition, the through-hole extends inside the coil antenna.

A mobile electronic device and method are provided. The mobile electronic device includes a printed circuit board (PCB) built into a central area of the mobile electronic device and including at least one of a first loop antenna or a second loop antenna; a processor electrically connected to the at least one of the first loop antenna or the second loop antenna; a memory electrically connected to the processor, and configured to store card information related to a payment, wherein the processor is configured to determine whether the mobile electronic device is close to an external payment terminal, using the first loop antenna; and generate, if the mobile electronic device is close to the external payment terminal, a magnetic field signal including the card information, via the at least one of the first loop antenna or the second loop antenna, in response to a payment command.
