A transaction card can be manufactured from rigid materials, such as glass, stone, or ceramics. The transaction card can have a first rigid layer having a first external surface and a first internal surface, with a pocket within the first external surface of the first rigid layer. The transaction card can have a second rigid layer having a second external surface and a second internal surface. A binding layer can be located between the first rigid layer and the second rigid layer can affix the first rigid layer to the second internal layer. An integrated circuit chip can be affixed within the pocket of the first rigid layer. A rim can extend from the first external surface of first rigid layer around a first edge of the first rigid layer and a second edge of the second rigid layer and onto the second external surface of the second rigid layer.

A long-distance radio frequency electronic identification tire structure is provided. When the production of the tire is completed and an electronic tag reading device is used for identification, an RFID chip of an ultra high frequency electronic tag of a main tire body receives and sends an electromagnetic wave signal generated by a far-field copper film antenna and the electronic tag reading device. The frequency band and the bandwidth of the electromagnetic wave signal are adjusted by a frequency band/bandwidth adjustment portion, and first and second field effect adjustment grooves of first and second field effect adjustment portions are configured to adjust the field effect when a tire bead bundle and a steel belt layer reflect the electromagnetic wave signal, so that the electronic tag reading device can read the identification code of the ultra high frequency electronic tag at a wide angle and a long distance.

A vehicle identification means (10) that has an at least partially electrically conductive film (12) and a hologram (36) and/or a reflective film. In addition, at least one data carrier (26), which can be read out in a contactless manner, having an antenna is provided. The hologram (36) is implemented as an antenna for the data carrier (26). A separate antenna is therefore no longer necessary. In addition, multiple antennas can be provided in parallel.

Dispensing devices and systems for oral transmucosal administration of small volume drug dosage forms to the oral mucosa are provided. The dispensing device may be a single dose applicator (SDA), or an electromechanical device comprising a means for patient identification such as a wrist worn RFID tag and annular bidirectional antenna together with a lock-out feature.

A wireless power receiver according to an embodiment wirelessly receives power from a wireless power transmitter. The wireless power receiver includes a printed circuit board having a reception space in a predetermined area, a receiving coil disposed in the reception space of the printed circuit board for receiving power from the wireless power transmitter, and a short-range communication antenna disposed on the printed circuit board while surrounding the receiving coil.

An object of the present disclosure is to improve visibility while suppressing an impedance of an antenna pattern formed on a conductive film. In a film base material on which an antenna pattern for near field communication is formed, the antenna pattern is formed of a metal having excellent conductivity. The antenna pattern is formed into a loop line shape with three to five turns and has a length of 200 to 500 mm, an interval between adjacent loop lines of 200 to 400 μm, and a line width of 4 to 20 μm. The thickness of the antenna pattern is set to a value calculated by the following Formula (1) so that the impedance at a maximum load becomes equal to or less than 50Ω.

Thickness=Specific Resistance×Length/(Impedance×Width)   Formula (1)

Disclosed is an electronic entity having a transponder which includes a body provided with a recess and, inside the recess, a transponder including a mounting supporting an antenna formed by at least one turn running along the contour of the module and a microcircuit, the antenna and microcircuit being connected to one another, plates of conductive material being formed on each of the surfaces facing one another, covering 60-90% of the surface defined by the one or more turns of the antenna, forming a capacitor connected in parallel on the antenna, and the body including an annular metal area, the inner contour of which projects into the plane of the mounting surrounds the mounting and is suitable for concentrating the field lines toward the inside of the turn, the capacitor defining, with the antenna and the microcircuit, a given resonance frequency substantially equal to the frequency of an external reader.

A radio frequency identification (RFID) tag that includes an antenna having a spiral form disposed on a major surface of a flexible substrate is described. The RFID tag includes a first terminal disposed at a first end of the antenna and a second terminal disposed at the second end of the antenna. The RFID tag may include a pad portion along the length of the antenna between the first and second ends for mounting an integrated circuit. Except for the pad portion, a radius of curvature of the antenna along at least 90 percent of a length of the antenna between the first and second ends is greater than about 0.1 mm and less than about 10 mm.

A radio IC device includes an electromagnetic coupling module includes a radio IC chip arranged to process transmitted and received signals and a feed circuit board including an inductance element. The feed circuit board includes an external electrode electromagnetically coupled to the feed circuit, and the external electrode is electrically connected to a shielding case or a wiring cable. The shielding case or the wiring cable functions as a radiation plate. The radio IC chip is operated by a signal received by the shielding case or the wiring, and the answer signal from the radio IC chip is radiated from the shielding case or the wiring cable to the outside. A metal component functions as the radiation plate, and the metal component may be a ground electrode disposed on the printed wiring board.

In a smart card having an antenna structure and a metal layer, an insulator layer is formed between the antenna structure and the metal layer to compensate for the attenuation due to the metal layer. The thickness of the insulator layer affects the capacitive coupling between the antenna structure and the metal layer and is selected to have a value which optimizes the transmission/reception of signals between the card and a card reader.
