A radio frequency radiation shield device may comprise a receiver for detecting a near field radio frequency signal. The receiver may include one or more receiving antennas for target frequencies. The shield device may further comprise a signal processor that samples signal characteristics of a detected signal and determines a nullifying signal in response to detecting a signal characteristic of the detected signal on a receiving antenna meets a trigger threshold. The nullifying signal may comprise a modulated version of the detected signal. The shield device may further comprise a signaler for generating the nullifying signal. The shield device may further comprise a transmitter. The transmitter may include a transmitting antenna at target frequencies for transmitting the nullifying signal.

An antenna includes a substrate, a first circular metal strip disposed on a first surface of the substrate, and a second circular metal strip disposed on a second surface of the substrate. The first circular metal strip has a first end used as a feed end and a second end connected to a first end of a radio frequency resistor. The second circular metal strip has a first end used as a grounding terminal and a second end connected to a second end of the radio frequency resistor.

An electronic device base includes an upper case, a lower case, a base, a first hook component and a second hook component, a solenoid valve assembly, and a near field communication assembly. The upper case has an electronic device accommodation slot; the lower case is assembled to the upper case; the base is disposed between the upper and lower cases; the first and the second hook components are both disposed at the base. When the electronic device is placed into the electronic device accommodation slot, the first and the second hook components are forced by the electronic device to move along a first direction and a second direction, respectively, so the second hook component restricts the first hook component. The near field communication component is capable of communicating with an unlocking component and driving the solenoid valve assembly to actuate the second hook component to release the first hook component.

A coil assembly includes: a substrate; and a coil wiring coupled to the substrate and including a spiral wiring and a lead wiring, wherein the spiral wiring includes a first section forming an outer portion of the spiral wiring and a second section, disposed inside the first section, and having a line width narrower than a line width of the first section.

A method and system for conducting an online payment transaction through a point of sale device. The method includes receiving input from a user selecting an item for purchase through the point of sale device; calculating a total purchase amount for the item in response to a request from the user to purchase the item; and sending payment authorization for the total purchase amount from the point of sale device to a payment entity, in which the payment authorization is sent to the payment entity via a mobile communication device of the user. The method further includes receiving a result of the payment authorization from the payment entity through the mobile communication device; and completing the payment transaction based on the result of the payment authorization.

Embodiments of this specification provide a method and apparatus for quick enabling a service in an application program and an electronic device. When a user terminal receives tag content transmitted by a near field communication (NFC) tag, an operating system of the user terminal may enable an application program that has registered NFC. Then, the enabled application program uploads the tag content to a server. According to a service routed by the server after the server decodes the tag content, the application program executes the routed service.

An electronic tag programmed with an identification in a seat belt assembly is identified by reading the programmed identification via an electronic device embedded in a seat. In response to identifying the electronic tag, a determination is made that an occupant has not fastened a seat belt of the seat belt assembly to secure the occupant in the seat.

A method for anti-tracking of Bluetooth, comprising: a target Bluetooth device generating a first dynamic address every first pre-set time and broadcasting same; after connecting to a mobile device and obtaining a second dynamic address thereof, waiting to receive data sent by the mobile device; if the data is a pairing request, pairing with the mobile device, saving a second identity parsing key contained in the pairing request, returning a pairing response containing a first identity parsing key thereof to the mobile device, and continuing to wait to receive data; and if the data is a link encryption request, successively using identity parsing keys stored thereby of the mobile device to verify the second dynamic address, determining whether a second identity parsing key having been successfully verified exists, and if so, returning a success response to the connected mobile device and communicating with same, and ending the process, otherwise, returning an error code and disconnecting from same, and ending the process. In the present invention, a Bluetooth device periodically changes a dynamic address thereof, thereby effectively preventing data being stolen by a hacker.

A method for configuring a mobile terminal to control vehicle functions of a vehicle, where the mobile terminal and the vehicle each have a short-range radio system, includes receiving a request to a server to issue a vehicle key for the use of vehicle functions of the vehicle for a mobile terminal. The method also includes generating the vehicle key by the server, transmitting the vehicle key to a secure element of the mobile terminal, and storing the vehicle key in the secure element of the mobile terminal.

An NFC-enabled apparatus is disclosed. The apparatus includes a touch screen display and a near field communication (NFC) module comprising an NFC antenna and an NFC controller. In response to tagging between the NFC-enabled apparatus and the external NFC terminal, an NFC communication channel is established between the NFC-enabled apparatus and the external NFC terminal for data communication therebetween.
