  • Publication number: 20170098150
    Abstract: A dynamic transaction card that is manufactured using conductive plastic jumpers that will dissolve when in contact with a solvent used to tamper with the dynamic transaction card. Internal components of a dynamic transaction card may be manufactured using a synthetic or semi-synthetic organic material, such as, for example, plastics. These materials may be conductive to provide functionality to a dynamic transaction card, such as a connection between an integrated circuit and other card components such that when the materials dissolve, the connections are broken and the dynamic transaction card may be inactive due to the loss of various connections.

  • Publication number: 20160307089
    Abstract: 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 sensor layer, a display layer (including, for example, LEDs, a dot matrix display, and the like), a microcontroller/microprocessor storing firmware, Java applets, Java applet integration, and the like, an EMV processor, 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. A display layer may include enhanced features such as the use of LED display components as a photosensor.

  • Publication number: 20160307081
    Abstract: A dynamic transaction card with EuroPay-Mastercard-Visa (“EMV”)technology that includes an EMV interface connecting EMV contacts and an EMV processor to enable a multifunctional dynamic transaction card. A method of manufacturing a dynamic transaction card with an EMV interface connecting EMV contacts and an EMV processor. A dynamic transaction card with an EMV interface may be manufactured using a separate printed circuit board (PCB) layout with EMV contact patterns placed into the top surface of a molding to create the dynamic transaction card. The edges of the EMV contact patterns would be incorporated through holes, which are trimmed to scallops, to allow for surface mounting. The EMV interface may then include a connection between the EMV contact patterns and the EMV microprocessor such that the EMV microprocessor does not have to be placed directly beneath the EMV contact patterns.

  • Publication number: 20160308371
    Abstract: A printed circuit board (“PCB”) with a power source. The PCB and power source combination may be inserted into a small electronic device, such as a dynamic transaction card, which may include a dynamic transaction card or a EuroPay-MasterCard-Visa (“EMV”) card. For example, a PCB may be manufactured to attach a battery as a power source to one side of a PCB such that the integrated battery directly connects with at least a portion of the PCB side. A rapid energy storage device may also be utilized as a power source. Energy may be harvested from an EMV terminal to charge or recharge a dynamic transaction card or EMV card powered by a rapid energy storage device when the card is inserted into the terminal.

  • Publication number: 20160307190
    Abstract: A system for securely updating an electronic transaction card held by an account holder with an additional account and/or account data. 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 an issuer system. 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.

  • Publication number: 20160306977
    Abstract: An electronic device, such as a dynamic transaction card having an EMV chip, that acts as a TPM having a memory, an applet, and a cryptographic coprocessor performs secure firmware and/or software updates, and performs firmware and/or software validation for firmware and/or software that is stored on the electronic device. Validation may compare a calculated checksum with a checksum stored in EMV chip memory. If a checksum calculated for firmware and/or a software application matches a checksum stored in EMV chip memory of the transaction card, the transaction card may operate normally. If a checksum calculated for firmware and/or a software application does not match a checksum stored in EMV chip memory of the transaction card, the transaction card may freeze all capabilities, erase the memory of the transaction card, display data indicative of a fraudulent or inactive transaction card, and/or the like.

  • Patent number: 8706194
    Abstract: This patent document discusses assemblies and methods for remotely detecting a position of a surgical instrument in the presence of a magnetic field. In varying examples, a position detection system includes an encoder coupled to move in concert with the instrument. The encoder includes an a translucent substrate and light blocking indicia disposed thereon. A light source and a light detector array are effectively disposed outside of the magnetic field. Light from the light source is carried to an encoder first side using an input optical fiber, while the light passing through the encoder is received at an encoder second side by an output optical fiber. The light received by the output optical fiber is transmitted to the light detector array, which converts the received light to position representative electrical signals. Such signals are subsequently transmitted to a control module adapted to formulate and convey a position of the instrument.
