A system for securely updating an electronic transaction card held by an account holder with an additional account and/or account data is described. A dynamic transaction card may be securely updated with an additional account by using pre-stored shell data and/or inactive data, whereby the pre-stored shell data may be populated using data received from an issuer system and/or the inactive data may be activated via an activation signal received from a mobile device. A backend server may determine, via a fraud determination, expiration determination, and/or user-request, that new account data should be transmitted to an account holder. The dynamic transaction card may receive the data associated with a notification, update a display, instruct an EMV applet to use a key associated with a received EMV key identifier for signatures, and/or update any additional data stored on the dynamic transaction card.

A Radio Frequency Identification (RFID) tag according to one embodiment includes a housing configured for coupling to an object, control circuitry coupled to the housing, and a memory for storing information, the information including a service history of the object.

Systems and methods for secure and efficient transaction resolution and execution are provided. A method may include capturing, via a camera embedded in a smart card, an image of an object. The object may be associated with one of a plurality of service categories. The method may include processing the image and determining the service category, from the plurality of service categories, which is associated with the object. The method may also include determining a service provider that provides the service of the service category for a user associated with the smart card, and determining a monetary balance owed by the user to the service provider for the service. The method may also include executing a payment, via a wireless communication element that is embedded in the smart card, in the amount of the monetary balance, from an account associated with the user to the service provider.

A system and method for method for testing an energy harvesting tag, comprising: transmitting a harvesting signal to an energy harvesting tag at time T.sub.1; receiving a response signal from the energy harvesting tag at time T.sub.2; determining a capacitor charging time of the energy harvesting tag as a difference between T.sub.2 and T.sub.1; and assigning a pass value to the energy harvesting tag when the capacitor charging time is less than a predetermined threshold amount.

The present disclosure provides a photodynamic energy electronic label, a working method thereof, a managing method and a managing apparatus thereof. The photodynamic energy electronic label includes a photodynamic energy converter configured to convert light energy into electric energy, and a triggering circuit connected with the photodynamic energy converter and configured to send out a triggering signal to enable the photodynamic energy electronic label to be in a working state when an output of the photodynamic energy converter reaches a set condition.

Embodiments of the present disclosure generally relate to a wireless identification tag for association with a product to enable product self-identification and system and methods for use thereof. In one implementation, the tag may include at least one antenna tuned to receive energy transmitted at one or more frequencies within certain frequency bands. The tag may also include at least one transmitter that may be configured to send at least one identification signal. The tag may also include at least one circuit. The at least one circuit may be configured to detect whether energy is received in a certain frequency band, and to cause the at least one transmitter to operate in a mode corresponding to the certain frequency band.

Embodiments of the present disclosure generally relate to an appliance for holding electronically tagged products and for recording an association between the tagged products and the appliance, and system and methods for use thereof. In one implementation, the appliance may include a housing defining a cavity for retaining the electronically tagged products. The appliance may also include an exciter integrated with the housing and configured to trigger tags of the products to cause the tag of each product to transmit a unique tag ID. The appliance may also include a receiver for receiving transmission of each unique tag ID. The appliance may also include a communicator for outputting indications of identities of electronically tagged products retained in the cavity.

The present disclosure provides a circuit and a method for improving energy harvest for an RFID tag with a temperature sensor, where an instruction command sent by a card reader includes a modulated part to invoke temperature sensor functions, and an unmodulated constant-envelop RF signal part with an extended time of duration to charge a switched additional energy storage capacitor embedded in the circuit. The switched additional energy storage capacitor is connected to the circuit upon a mode control signal corresponding to the sensor operation mode of the RFID tag. Thus, the RFID tag with the temperature sensor is ensured to conform to the timing window protocol for regular downlink operations, and at the same time, is capable of meeting higher energy demand for a high accuracy temperature sensor operation.

Systems and methods for executing transactions with increased transactional efficiency and security via a smart payment instrument with self-contained transaction architecture are provided. Methods may include receiving information via a tactile sensor that is affixed to the instrument. Information may include a series of alphanumeric symbols. The receiving may be achieved by entering the symbols via the tactile sensor. Methods may include deciphering the information, via a payment interface component of the instrument, to generate payment data. Payment data may include a recipient and a payment amount. Methods may include transmitting to a payment gateway, via a wireless communication element embedded in the instrument, a request to execute a payment based on the payment data.

A dynamic transaction card that includes a number of layers, each of which may be interconnected to one another. For example, a dynamic transaction card may include an outer layer, a potting layer, a touch sensor layer, a display layer (including, for example, LEDs, a dot matrix display, and the like), a microcontroller storing firmware, Java applets, Java applet integration, and the like, an EMV chip, an energy storage component, one or more antenna (e.g., Bluetooth antenna, NFC antenna, and the like), a power management component, a flexible printed circuit board (PCB), a chassis, and/or a card backing layer. The card includes a secure element to receive visual impairment settings and alert data. A microprocessor can convert the alert data into impairment data based on the visual impairment settings. A display is generated based on the impairment data.
