A computer terminal typically includes a retractable conduit and an actuator connected to the retractable conduit. The retractable conduit typically includes a proximal end, a distal end, and a barrier between the proximal end and the distal end. The distal end is typically configured to engage a portal of a vehicle positioned proximate to the computer terminal. The actuator is typically configured to extend the distal end of the retractable conduit away from the computer terminal and toward the portal of the vehicle. The computer terminal is typically configured to determine that the vehicle is proximate to the computer terminal; determine a location of the portal of the vehicle; and transmit a control signal that causes the actuator to extend the distal end of the retractable conduit away from the computer terminal so that the distal end engages the portal of the vehicle.

A method of forming an image using a mobile terminal supporting near field communication (NFC) includes launching a mobile application corresponding to an application identifier of tag information of an NFC tag obtained through first NFC tagging, generating data of a job to be performed by an image forming apparatus through the mobile application when the NFC tag is detected again through second NFC tagging, the job being determined according to a state of the mobile application during the second NFC tagging, and transmitting the generated data to the image forming apparatus.

A system for monitoring and controlling building equipment includes a near field communications (NFC) tag, a temperature sensor, a mobile device, and a controller. The NFC tag is located within a building space and stores a tag ID uniquely identifying the NFC tag. The temperature sensor is associated with the building space and configured to measure a temperature of the building space. The mobile device reads the NFC tag and obtains the tag ID from the NFC tag via NFC. The controller receives the tag ID from the mobile device and uses the tag ID to identify the temperature sensor associated with the building space. The controller receives the measured temperature from the temperature sensor and provides the measured temperature to the mobile device. The mobile device displays the measured temperature via a user interface of the mobile device.

A method, an apparatus, and a system are provided for adjusting a data packet length in near field communication NFC. The method includes: determining, by an NFCC of a first NFC device, whether the NFCC is responsible for determining a maximum length value of data packets transmitted in subsequent communication; if yes, sending a first request comprising a first length value to a second NFC device, the first request further includes a first DID; receiving a first response that is returned by the second NFC device for the first request and that comprises a second DID; and when the first DID is the same as the second DID, using the first length value as the maximum length value of the data packets transmitted in the subsequent communication.

A method of transferring data between a first device and a second device comprises: bringing a first object into an activation zone of a near-field communication module so as thereby to establish a near-field communication link between the module and the first object. The near-field communication module sends a control signal to at least one of the first and second devices to begin a second communication session through a second, different channel between the first and second devices and the data is transferred between the first device and the second device in the second communication session. The second communication session is ended if the first object is removed from the activation zone.

Systems and methods for near-field communications with a mobile device are disclosed. In one embodiment, a computer-implemented method for near-field communication may comprise: detecting, by a source device located at a point-of-sale, the proximity of a receiving device; encoding purchase data on an audio signal with one or more ultrasonic frequencies; and transmitting the encoded purchase data to the receiving device, wherein the encoded purchase data is transmitted using a speaker of the source device.

Provided is an electronic apparatus that prevents leakage of confidential documents and the like that are stored in a storage device. When there is writing of power-supply-mode-switch-request information that is included in a Write request from a user-authenticated portable terminal to an NFC tag, a system-control unit instructs a power-supply-control unit to switch to a normal mode based on the power-supply-mode-switch-request information, and when the portable terminal is separated from the NFC tag, instructs the power-supply-control unit to return to the power-supply mode before the instruction.

An electromagnetic Extremely High Frequency (EHF) communication chip includes one or more local oscillator circuits, a transducer circuit and at least one of a modulator or a demodulator coupled to the transducer circuit. Each of the local oscillator circuits may have a local oscillator and configured collectively to generate first and second carrier signals having respective first and second EHF frequencies. The first EHF frequency may be different than the second EHF frequency. The transducer circuit may have a first transducer for transmitting and receiving EHF communication signals. The modulator may be coupled to the local oscillator circuits for modulating the first carrier signal or the second carrier signal with a first transmit base data signal. The demodulator may be for demodulating the first carrier signal or the second carrier signal to produce a first receive base data signal.

In one aspect, a method of wireless communication by a first wireless device includes detecting a near field communication (NFC) read of the first wireless device. The NFC read may be a read initiated by a second wireless device via an NFC interaction between the first wireless device and the second wireless device. The method also includes adjusting at least one Bluetooth paging scan parameter of the first wireless device in response to detecting the NFC read.

The invention provides for optimizing Near Field Communications (NFC) at a NFC-enabled interaction terminal configured for conducting user interactions. The invention provides for a user to designate which user credentials are applied to which type of NFC-enabled interaction terminals. A NFC-enabled interaction terminal-specific Application Identifier (AID) is assigned to the user credentials, and, in use, the AID list that is communicated, via NFC, by a mobile communication device to the NFC-enabled interaction terminal includes the NFC-enabled interaction terminal-specific AID, which implements an AID selection order that prioritizes use of the AID. In response, the application executing on the mobile communication device processes commands from the NFC-enabled interaction terminal using the pre-designated user credentials.
