Described is a system (SY) comprising a card (DV1) and a peripheral device (DV2) configured to cooperate together to enable a biometric print to be acquired. The smartcard (DV1) includes a biometric print sensor (10) and a control module for transmitting control signals (SG) to the peripheral device (DV2), each control signal (SG) being defined by a respective single level of an electrical characteristic. Apart from a possible internal power supply, the peripheral device (DV2) may include passive components only, including a user interface (20) configured to put itself into a predetermined state in response to each received control signal (SG), so as to guide a user in acquiring a biometric print by means of the biometric print sensor (10).

Techniques are described for performing secure card not present (CNP) transactions using integrated circuit chip-enabled cards. The techniques include continually or periodically tracking a location of a user's card by a user computing device, e.g., a “smart” phone, and storing a log of datasets relating to the location of the user's card at a server device. Based on the tracking, the user computing device may alert the user via a push notification or other message when the user's card is not within a preset range of the user computing device. In addition, an authentication server determines a location of a purchaser computing device attempting to perform a CNP transaction using the user's card information, and compares the location of the purchaser computing device with a most recent location of the user's card retrieved from the log of datasets to determine whether to approve the CNP transaction.

The disclosed embodiments provide a payment card. The payment card may have a first face and a second face opposite the first. Additionally, the payment card may comprise a first smart chip, the first smart chip having contacts that are electronically accessible from the first face of the card. The payment card may further comprise a first antenna coupled to the first smart chip, the first antenna providing near-field contactless access to the first smart chip and a second smart chip, the second smart chip having contacts that are electronically accessible from the second face of thecard. Additionally, the payment card may comprise a second antenna coupled to the second smart chip, the second antenna providing near-field contactless access to the second smart chip and an RF block that electronically isolates the first antenna and the second antenna from each other.

The application describes generation of a data structure that enables comparison of any diamond to any other diamond. The data structure is generated via a sampling process and a computer system for acquisition of diamonds of a valid statistical sample having a predefined sample size. The process comprises tabulating the frequencies that diamonds of various grade combinations are available in an overall population of diamonds, then using a bidding process described herein to acquire a valid statistical sample of diamonds. The data for the sample of diamonds are then inputted into a Linear Programming and Mixed-Integer optimizer configured to sort all diamonds of the sample into sets with a median that is a minimal distance from the median on a scarcity basis, subject to various constraints, such as the number of diamonds in each set and a minimum total carat weight.

Integrated circuit package (ICP) with: (i) stored information pertaining to an amount and/or value of precious material present in the ICP; and (ii) sensor for detecting an amount of precious material present in the ICP. In some embodiments the ICP is embedded in a smart card for use with a smart card reader system that can communicate data to and/or from the ICP.

A home system can include a central control unit, which can be paired with a plurality of accessory devices including a client device. The client device can receive an instruction signal from a contactless card. An application of the client device can process the instruction signal and generate an event signal. The client device can transmit the event signal to the central control unit and the central control unit can transmit a device signal to one or more of the accessory devices. The device signal can instruct the one or more accessory devices to perform one or more tasks.

Embodiments of the present invention provide a method, program, and apparatus that may identify a device by using a virtual code generated based on a unique value of a chip inside a device without a separate procedure for identifying the device. Furthermore, embodiments of the present invention provide a method, program, and apparatus that may generate a virtual code, which is not matched with any other code, whenever a code for identifying a device is requested. Moreover, embodiments of the present invention provide a method, program, and apparatus for identifying a device that may add and use only an algorithm without changing a conventional process.

An approval request is transmitted for a cryptoasset transaction in accordance with a policy stored in a hardware security module (“HSM”). The policy specifies at least one specific approver required for approval of the cryptoasset transaction. The approval request is transmitted to a computer device associated with the specific approver and is configured to cause the computer device to prompt the specific approver to approve the cryptoasset transaction. A security key is received from a hardware security token associated with the specific approver. The security key indicates an approval of the cryptoasset transaction. A risk analysis module authenticates an identity of the specific approver based on the security key. Responsive to the authenticating of the identity of the specific approver, the HSM signs the cryptoasset transaction using a cryptographic key stored in the HSM.
