NFC standards include a plurality of types (Type A, Type B and Type F). The communication controller performs a polling so as to detect a portable device that communicates in accordance with the NFC standards. The memory stores region information indicating a region where a vehicle is to be used. Based on the region information, the communication controller stops the polling of a type among the plurality of types that is not used in the region.

In accordance with an embodiment, a wireless tag reading apparatus includes an antenna, first and second power feeding ports, and a controller. The first power feeding port feeds electric power into the antenna so as to emit the first linearly polarized wave from the antenna. The second power feeding port feeds electric power into the antenna so as to emit the second linearly polarized wave from the antenna. The controller sets a ratio of a time of power feeding from the first power feeding port to a time of power feeding from the second power feeding port to take a value according to a ratio of the number of wireless tags existing in the direction of the first linearly polarized wave to the number of wireless tags existing in the direction of the second linearly polarized wave.

A system and a method are disclosed that enable a mobile device to use an encoded tag to initiate and maintain communications with at least one remote server. The encoded tag is positioned to identify a point of interest, and in response to using the mobile device to scan the encoded tag, communications regarding the point of interest may be initiated. A single encoded tag may be used to obtain and update recorded information about the point of interest, to notify others about an issue related to the point of interest, to log into the system, and to wait to be alerted about an issue related to the point of interest. If an issue relating to a point of interest has been reported, the system and method may monitor the reported issue to ensure that an action has been taken to address the reported issue.

Systems for determining a price of goods, reducing food waste, optimizing markdowns for the goods, and controlling prices of the goods in a retail setting are described. A scanner scans a readable identification tag affixed to a good during a time period. A pricing engine of at least one server queries, dynamically and in real-time, a database to identify, from the readable identification tag, the good and the information associated with the good. The pricing engine then applies algorithms to the identified good to calculate a price of the good and modify the calculated price of the good during the time period to optimize a target function. The optimization of the target function depends on price-calculation factors associated with a shelf-state of the good and associated with a future stock of the good. At least one calculated price based on the expiration date of the good is displayed.

Control over the operation of a dimmable light is supported by an interface circuit between the dimmable light and a near-field radio frequency communication controller. The interface circuit includes a first circuit that receives at least one control set point through a near-field radio frequency communication issued by the near-field radio frequency communication controller. A second circuit of the interface generates one or more electric signals in pulse width modulation based on the control set point.

A delivery system includes a database configured to store information of a customer where the information includes a default payment method, a communication system configured to communicate with an autonomous vehicle and with a device of the customer, where the device includes a display screen having a button to summon an autonomous vehicle, at least one processor, and a memory storing instructions. The instructions, when executed by the at least one processor, cause the delivery system to receive an indication via the communication system that the button on the device of the customer has been clicked, and instruct the autonomous vehicle to travel to a location of the customer.

Provided herein is an autonomous or semi-autonomous vehicle fleet comprising a plurality of electric autonomous vehicle for apportioned display of a media, operating autonomously and a fleet management module for coordination of the autonomous vehicle fleet. Each autonomous or semi-autonomous vehicle comprising a screen configured to display the media. Activation, deactivation, brightness modification, in combination with specific media selection enables more efficient media display.

A device connectable to a reader of an access control system includes an antenna, an ultra-wide band (UWB) front end circuit, a controller, and a communication link. The (UWB) front end circuit is connected to the antenna to facilitate UWB communication with a credential device. The controller is connected to the UWB front end and configured to perform ranging for the credential device using the UWB communication. The communication link is configured to interface with the reader.

Embodiments of the present disclosure generally relate to a wireless identification tag with varying identity, and system and methods for use thereof. In one implementation, the tag may include at least one transmitter configured to transmit a tag ID. The tag may also include at least one circuit. The at least one circuit may be configured to receive a first trigger at a first time and generate in a quasi-random manner a first decipherable ID uniquely identifying the tag, and cause the at least one transmitter to transmit the first decipherable ID. The at least one circuit may also be configured to receive a second trigger at a second time and generate in a quasi-random manner a second decipherable ID different from the first decipherable ID and uniquely identifying the tag, and cause the at least one transmitter to transmit the second decipherable ID.
