An RFID card includes a smartcard controller that receives power from a host device. The RFID card also includes a small inductive device capable of inductive coupling with an RFID reader. The small inductive device is small enough to fit in the form factor of a memory card or SIM card. Enhancement circuits enhance the usable read and write distance of the RFID card.

A near field communication (NFC) device capable of operating by being powered by the field includes an NFC module for generating an electromagnetic carrier signal and modulating the carrier signal, and an antenna circuit coupled to and driven by said NFC module with the modulated carrier signal. A differential power combiner circuit is coupled to said NFC module via output terminals of said NFC module. A powered by the field circuit of the NFC device is adapted to harvest energy from an external field to power said NFC device. The power by the field circuit has a first terminal coupled to an output of said differential power combiner circuit via a first impedance block and a second terminal coupled to an input of said antenna circuit via a second impedance block. The NFC device is adapted to be able to operate in a powered by the field card mode.

An aircraft measurement system includes an interrogator and an optical sensor assembly. The optical sensor assembly includes an optical sensor connected along a sensor path to the interrogator, a data storage device, and a control circuit connected along a power path to the interrogator. The sensor assembly also includes an opto-electric device for converting an optical signal to an electric current, connected along the power path between the interrogator and the control circuit, to power the data storage component through the control circuit, and a transmitter operationally connected to the control circuit and connected along a data path to the interrogator, to provide operational data along the data path to the interrogator. The data storage component provides operational data to the interrogator across the data path, and the interrogator is configured to receive sensor data from the sensor across the sensor path.

A wearable device receives ticket information for an event and information indicating a quantity of funds allocated from an account, associated with a user of a user device, to the wearable device, and stores the ticket information and the information indicating the quantity of funds. The wearable device utilizes a wireless component to pair the wearable device and the user device, and provides, to the user device and via the wireless component, the ticket information and information indicating access privileges for the event. The wearable device generates a token for a PoS device for a charge incurred at the event during an offline transaction with the PoS device, and provides, via a NFC component, the token to the PoS device. The wearable device provides, to the user device and via the wireless component, information indicating that that the token was provided to the PoS device.

An RFID card includes a smartcard controller that receives power from a host device. The RFID card also includes a small inductive device capable of inductive coupling with an RFID reader. The small inductive device is small enough to fit in the form factor of a memory card or SIM card. Enhancement circuits enhance the usable read and write distance of the RFID card.

A method and device for protecting sensitive information stored on a mobile device capable of wireless communication is described. The protection is provided by permitting wireless transmission of the sensitive information only if data received from an optical sensor or a magnetic sensor satisfies a predetermined requirement.

An embodiment device includes a first housing formed of a first radio-transparent material and having an outer perimeter surface including a first outer perimeter portion and a second outer perimeter portion, the outer perimeter surface having one or more recesses, each of the one or more recesses extending from one of the first outer perimeter portion or the second outer perimeter portion into a body of the first housing, a second housing formed of a second radio-transparent material and secured to the first housing, a near field communication (NFC) chip disposed between the first housing and the second housing, a link having a first end and a second end extending into the body of the first housing.

An electronic transaction card communicates with an add-on slot of an intelligent electronic device. The add-on slot may be a memory card slot. The intelligent electronic device may be a mobile phone or other device with or without network connectivity. The electronic transaction card may have magnetic field producing circuitry compatible with magnetic card readers, smartcard circuitry, other point-of-sale interfaces, or any combination thereof.

Present systems and methods are directed to an entertainment system for an environment. The entertainment system includes a container configured to hold one or more user devices and a sensor configured to detect a presence of the one or more user devices in the container and to generate data indicative of the presence of the one or more user devices in the container. The entertainment system also includes one or more processors configured to identify the presence of the one or more user devices in the container based on the data, and in response to identifying the presence of the one or more user devices in the container based on the data, instruct the one or more user devices to play one or more audio tracks.

A mounted token system is configured to be worn by a wearer as a part of the grieving process. The mounted token system may include a token with an tracking indicator, a token mount, and a server. The token mount includes an anterior segment which includes an anterior opening, and a posterior segment moveable relative to the anterior segment. The token mount is configured to secure the token therein. At least a portion of the token is visible from an anterior side through the anterior opening. The server performs the following steps: present, to a first user via a graphical user interface, an invitation to provide information indicative of the tracking indicator of the token; receive, from the first user, information indicative of the tracking indicator; and store information indicative of the tracking indicator. The token may then be passed to a subsequent wearer, utilizing a new token mount.
