A multiple ply printed product and a method of producing it are described. The method comprises providing a substrate layer having a first surface supporting at least one wireless communication chip and a second surface, reverse to the first surface. A first paper stock having a first surface and a second surface is also provided. A first bonding operation is performed to substantially bond together the first surface of the substrate layer and the second surface of the first paper stock, to sandwich the wireless communication chip between the first paper stock and the substrate layer; providing a second paper stock having a first surface and a second surface. At least one of the first surface of the first paper stock and the second surface of the second paper stock may be printed on. A second bonding operation is performed to bond together the first surface of the second paper stock and the second surface of the substrate layer, to form a multiple ply printed product where the first surface of the substrate layer supports a plurality of wireless communication chips and the multiple ply printed product is a sheet on which is printed a plurality of business cards, each business card corresponding to a respective wireless communication chip.

A multimedia card includes a substrate, and a main control chip, a memory chip, and an interface contacts that are disposed on the substrate. The main control chip and the memory chip are covered with a packaging layer. The interface contacts includes a power contact, configured to receive a first voltage that is input from the outside; and a transformer circuit is further disposed on the substrate, is coupled to the interface contacts, the main control chip, and the memory chip, and is configured to convert the input first voltage into a second voltage, to provide two types of power supplies with the first voltage and the second voltage for the main control chip and the memory chip. In the foregoing manner, an area of the multimedia card is reduced, and a quantity of working modes of the multimedia card increases.

This invention relates to a square with rounded angles smart card, in a non-conventional size, with a plurality of electronic circuits embedded in a specified pattern and assigned to different functionalities. This smart card with the means of a wired or contactless reader-writer apparatus, can be used for commercial, business or payment transactions and offers a number of advantages versus the old cards.

The utility model relates to the field of radio frequency identification, in particular, to the one containing a radio frequency tag in printing paper for typographical printing. The technical result is the creation of the technical solution as an alternative to the known one. The sheet material with the radio frequency identification is characterized in by the fact that it is made in the form of a rectangular sheet with a layer for printing, a length of 480 mm and a width of 325 mm, and it contains an antenna and a chip placed inside the sheet, what's more one of the sheet angles is made with a 45° bevel and a length of 10 mm.

Universal cards are used in place of all the other traditional cards which a person may want to carry. The universal card can include a short range communications transceiver to communicate with a mobile device. The mobile device can include a user interface and an e-wallet application so that the user can interface with the e-wallet application for programming the universal card via the short range communication link. Once programmed, the universal card emulates a function of a traditional card.

Embodiments are discussed herein related to radio frequency identification (“RFID”) and, more particularly, to systems, methods, apparatuses, computer readable media products and other means for integrating two transponders into a tag, where each transponder functions independent from and does not couple with the other transponder. In some embodiments, one of the transponders can be a near field RFID transponder and the other a far field transponder. The near field RFID transponder can be used to, among other things, authenticate the far field RFID transponder. In some embodiments, the far field RFID transponder can be encoded to transmit generic information, while the near field RFID transmits more detailed or user-specific information. Additionally, in some embodiments, the near field and far field RFID transponders can operate in accordance with the same wireless protocol and include their own circuitry and antenna.

A radiocommunication device, configured to implement a communication method, including an antenna for picking up at least one set of electromagnetic waves and/or for radiating at least one first group of data and/or at least one second group of data. The device further includes at least one first radiocommunication circuit, configured to receive at least one set of electromagnetic waves and/or to transmit at least one first group of data, and at least one second radiocommunication circuit, configured to receive at least one set of electromagnetic waves and/or to transmit at least one second group of data.

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.

An electronic module for a chip includes a first dielectric substrate provided on one of the faces thereof with a first microelectronic chip whose input/output terminals are connected to first connection pins which are arranged around the first microelectronic chip, and a second dielectric substrate which is placed directly opposite the first substrate and which is provided on one of the faces thereof with a second microelectronic chip whose input/output terminals are connected to second connection pins which are arranged around the second microelectronic chip. The first and second microelectronic chips are arranged on the faces of the substrates directed towards the interior of the electronic module. A dielectric shim has a calibrated thickness and separates the first and second dielectric substrates. The shim has through-holes or vacancies accommodating electrically conductive materials connecting some of the first connection pins to some of the second connection pins.

An RFID tag includes a circuit board, an RFID IC and a functional module. The circuit board has an antenna conductor. The RFID IC is mounted on the circuit board. The functional module is connected to the circuit board through a lead wire. An electrical length of a connection wiring that electrically connects the functional module to an element on the circuit board is within ±10% of an integral multiple of a half wavelength of a radio signal that the RFID IC transmits or receives.
