An apparatus is disclosed herein. The apparatus includes a first liner, a second liner, one or more fastening components, and one or more prongs. The one or more fastening components couples the first liner to the second liner, defining an opening between. The one or more prongs are positionable between a closed position within the opening and an open position exterior to the opening. The one or more prongs include a payment prong. The payment prong includes a body free, a payment chip receptacle, and a payment chip. The body is free from any personal identification information. The payment chip receptacle is attached to the body. The payment chip is positioned in the payment chip receptacle. The payment chip is removable therefrom.

An example method of identifying a touch gesture on a user is provided. The method includes receiving, by one or more transducers of a wearable device, a set of signals that establish a signal pathway to the wearable device. The method also includes, while receiving the set of signals, determining baseline characteristics for the signal pathway, and sensing a change in the baseline characteristics caused by user interaction with an affordance of a user interface projected or perceived on the user's appendage. The method further includes, in accordance with a determination that the sensed change in the baseline characteristics satisfies a contact criterion, reporting a candidate touch event on the user's appendage to a separate electronic device that creates the user interface or is in communication with another electronic device that creates the user interface.

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.

A dynamic monitoring system with radio-frequency identification includes a radio-frequency identification (RFID) tag, at least two radio-frequency identification (RFID) detectors and a processing device. The RFID tag is installed on a moving user. When the user enters a preset detection range, at least two RFID detectors detect the RFID tag and generate an identification signal, respectively. The processing device is coupled to at least two RFID detectors. The processing device generates a distance signal between the RFID tag and the at least two RFID detectors according to the identification signals and positions of the at least two RFID detectors. The processing device generates a positioning signal relevant to a position of the RFID tag within the preset detection range according to the distance signal.

The disclosed computer-implemented method may include transmitting, by at least one radar device, to at least one transponder located within a physical environment surrounding a user, a frequency-modulated radar signal that has a first type of polarization, and receiving, by the at least one radar device, signals that have a second type of polarization, the second type of polarization being different than the first type of polarization, detecting, by a processing device communicatively coupled to the at least one radar device, a signal that has the second type of polarization and was returned to the at least one radar device from the at least one transponder in response to the frequency-modulated radar signal, and calculating, by the processing device, a distance between the at least one transponder and the at least one radar device. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods are described related to using flexible circuitry in a payment accessory. In one embodiment, a payment device comprises a computing device and a memory. The computing device is configured to store a first biometric identifier for a first user and a second biometric identifier for a second user. The first biometric identifier is associated with a first transaction account and the second biometric identifier is associated with a second transaction account. A scanned biometric identifier of the first user is received. The first user is authenticated by matching the scanned biometric identifier to the first biometric identifier. The transponder is activated in response to matching the scanned biometric identifier to the first biometric identifier. The first transaction account is transmitted to a point of sale (POS) device for processing the payment transaction based on the first biometric identifier being linked with the first transaction account.

An event administration system is disclosed with a server connected to the internet to present a registration webpage to a remote event participant desiring to attend an event; a database connected to the server, the database stores information about the event participant and the event; an administrator module operated by an administrator of the system, the administrator can create and edit the event. The system allows registration register until the event starts and after the start of the event and can also provide a profile for participants that keeps track of their event statistics.

A system for controlling an industrial vehicle comprises an information linking device, a badge communicator, an operator badge, and a controller. The controller controls the industrial vehicle operating state by identifying that an operator possessing the operator badge has approached the industrial vehicle, communicating with the server via the information linking device to authenticate the operator as authorized to operate the industrial vehicle, and pairing the operator badge with the industrial vehicle upon determining that the operator is authorized to operate the industrial vehicle. Moreover, the controller controls the industrial vehicle operating state by controlling the industrial vehicle based upon a location of the operator badge relative to the industrial vehicle.

An authentication system configured to identify counterfeit articles. The authentication system configured to capture and scan an optical code engraved on an artifact, decode the optical code to determine a unique code associated with an article, transmitting the unique code to the authentication server and receiving a result of authentication from the authentication server to verify the authenticity of the article being scanned.

Provided is a wearable device, including a base configured to be worn by a user, at least one data element at least partially positioned on or within the base and programmed or configured to have account data stored thereon, and at least one antenna including an open circuit, the at least one antenna at least partially positioned on or within the base and configured to transmit at least a portion of the account data and receive at least a portion of transaction data from at least one target device when the open circuit of the antenna is closed and becomes powered by at least one power source. Other expressions are also disclosed.
