A retrofitted credit card including a certified smart card chip, a display and retrofitted emulation circuitry operative to enable the certified smart card chip to communicate information to the display notwithstanding that the certified smart card chip is configured for communication only with an external read/write device.

A transaction card includes at least one metal layer having one or more apertures therein. A light guide is disposed beneath the metal layer. The light guide has a light output and a light input. The light output is positioned to transmit light through at least the one or more apertures of the metal layer. At least one LED is positioned to transmit light into the light input of the light guide.

An antenna device includes a power feed coil and a ring-shaped conductor arranged about an axis and a ring-shaped conductor including first and second edge end portions in an axial direction and a cavity inward from the first edge end portion. At least a portion of the cavity overlaps with a coil opening of the power feed coil when seen from the radial direction. The power feed coil causes electric field coupling, magnetic field coupling, and/or electromagnetic field coupling with the cavity. The ring-shaped conductor defines and functions as a booster antenna of the power feed coil. A substantial coil opening defining and functioning as an antenna is larger than that when only the power feed coil is provided, thus facilitating coupling with a communication partner-side antenna coil.

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.

Systems and methods for augmenting a dedicated payment instrument to leverage built-in access to real-time support from a central system are provided. Methods may be executed via computer-executable instructions that are stored in a non-transitory memory of the instrument and run on a microprocessor embedded in the instrument. Methods may include receiving a request from a user of the instrument, via one or more sensors, to initiate a support session. The sensors may include a camera, a microphone, and/or a tactile sensor. Methods may include transmitting the request to the central system via a wireless communication element, and receiving, from the central system, support session data. Methods may also include displaying, on a display screen, information based on the support session data.

The present disclosure provides a card shaped mobile payment device, which includes a card shaped casing and an offline payment execution module configured for executing an offline payment operation and disposed in the card shaped casing. The offline payment execution module includes a display module, a security chip, an antenna unit and a central control unit. The display module is used for displaying card information; the security chip is used for generating a token information, which is time-sensitive, and executing a transaction procedure. The antenna unit is electrically connected to the security chip for providing the token information to a transaction device. The central control unit activates the security chip according to a received identity authentication result, and provides a card index information corresponding to the card information to the security chip, so as to access a stored card credential and generate the token information.

A mobile payment device includes a central control unit, an identity authentication module, an input interface, a display module, a security chip, an induction antenna and a cuboid casing. The central control unit is electrically connected to the identity authentication module, the input interface, the display module, and the security chip. The central control unit selects, according to an input signal inputted by a holder of the mobile payment device, one of at least one card information displayed on the display module to allow the selected card information to serve as payment card information and starts the security chip according to a signal inputted by the holder before making payment, thereby allowing the security chip to provide the payment card information to the induction 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.

A transaction card includes at least one metal layer having one or more apertures therein. A light guide is disposed beneath the metal layer. The light guide has a light output and a light input. The light output is positioned to transmit light through at least the one or more apertures of the metal layer. At least one LED is positioned to transmit light into the light input of the light guide.
