A dynamic transaction card including: one or more light emitting elements; a transceiver; and an embedded microprocessor configured to: receive, from a transaction terminal, a location information corresponding to a current location of the transaction terminal; wirelessly transmit, via the transceiver and to a mobile device, the location information; receive an indication that a location-specific security concern exists; and in response to receiving the indication, control the one or more light emitting elements to display a visual indication corresponding to the location-specific security concern.

The present disclosure is related to a field of payment transactions using a card that discloses a computer-implemented method and a system for restricting a transaction while using a payment card. A card processing server may receive card details, a transaction amount, a flag, and signature data of the payment card from a remote terminal upon initiating a transaction using the payment card. Further, the card processing server validates the payment card based on the card details and the signature data of the payment card and thereafter determines a value associated with the flag upon successful validation. The value associated with the flag indicates one of two conditions, e.g., a true condition and a false condition. Based on the condition indicated by the flag, the card processing server performs one of a first action and a second action related to either processing or declining the transaction.

In some embodiments, a smart card may include a substrate with a first side and a second side. A first protective layer covers the first side and a second protective layer covers the second side of the substrate. Circuitry held in the substrate includes electronic interconnects for interconnecting circuitry elements. The circuitry elements include a processor, power circuitry for powering the circuitry elements, and an environmental detection sensor for respectively detecting a predetermined environmental parameter. The processor is configured to receive an output from the environmental detection sensor, to determine from the output that the environmental detection sensor detected an environmental alert trigger condition, and to generate an alert that is representative of the environmental alert trigger condition. The protective layers include pores in a region proximate to the environmental detection sensor for exposing the environmental detection sensor to an environment around the smart card.

Various embodiments are generally directed to copying data to a clipboard of a mobile device from a contactless card using NFC. A mobile device may issue a request to read data from the contactless card. The contactless card may generate encrypted data in response to the request. The mobile device may receive the encrypted data via NFC and transmit the encrypted data to a server for verification. The server may verify the encrypted data and transmit an indication of an account number for the contactless card to the mobile device. The mobile device may then copy the account number to a clipboard of the mobile device.

Provided herein is a method, apparatus, and system for detecting conditions indicative of an attempt to attach a skimming device to a payment device. Methods may include monitoring at least one wire among a plurality of wires between a card reader device and a motherboard; determining voltage consumption; determining current consumption; identifying a change in voltage consumption or current consumption satisfying a predetermined value; and providing for transmission of an alert of a condition indicating possible attachment of a card skimming device. Methods may include generating a status message periodically and transmitting the status message to a remote entity. The change in voltage consumption or current consumption satisfying the predetermined value may include a voltage instability exceeding a predetermined range about an anticipated voltage. The change in voltage consumption or current consumption satisfying the predetermined value may include a decrease in current satisfying the predetermined value.

Technology is described for providing and using a thermo-sensitive payment card. An example payment card comprises a card substrate and a personalization layer overlaying the card substrate. The personalization layer includes a first region and a second region surrounding the first region. The first region includes an account number associated with an account of a user, and the account of the user is maintained by a payment service system that issues the payment card. At least one of the first region or the second region comprises a thermochromic ink such that application of heat to the first region or the second region having the thermochromic ink causes a change in color of the personalization layer so as to reveal the account number.

Apparatus and methods for a payment instrument are provided. The apparatus may include a primary chip positioned on an outer face of the payment instrument and a power source. The apparatus may include a first supplementary chip, a second supplementary chip, and a third supplementary chip. Each of the first, second and third supplementary chips may be positioned within a thickness of the payment instrument and configured to draw power from the power source.

A transaction card construction and computer-implemented methods for a transaction card are described. The transaction card has vector formatted visible information lasered onto its surface. In some embodiments, systems and methods are disclosed for enabling the sourcing of visible information using a scalable vector format. The systems and methods may receive a request to add a first plurality of visible information to a transaction card and capture an image of the first plurality of visible information. The systems and methods may also map the image to a bounding box and convert the mapped image into vector format. In addition, the systems and methods may provide the converted image to a laser machine.
