The present disclosure provides a card shaped mobile payment device, which includes a card shaped casing and an offline payment execution module configured for executing an offline payment operation and disposed in the card shaped casing. The offline payment execution module includes a display module, a security chip, an antenna unit and a central control unit. The display module is used for displaying card information; the security chip is used for generating a token information, which is time-sensitive, and executing a transaction procedure. The antenna unit is electrically connected to the security chip for providing the token information to a transaction device. The central control unit activates the security chip according to a received identity authentication result, and provides a card index information corresponding to the card information to the security chip, so as to access a stored card credential and generate the token information.

A mobile payment device includes a central control unit, an identity authentication module, an input interface, a display module, a security chip, an induction antenna and a cuboid casing. The central control unit is electrically connected to the identity authentication module, the input interface, the display module, and the security chip. The central control unit selects, according to an input signal inputted by a holder of the mobile payment device, one of at least one card information displayed on the display module to allow the selected card information to serve as payment card information and starts the security chip according to a signal inputted by the holder before making payment, thereby allowing the security chip to provide the payment card information to the induction antenna.

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.

Authenticating a secure element payment card includes transmitting a cold reset signal to the payment card and receiving an answer-to-reset message therefrom. The answer-to-reset message includes governing rules for performing a transaction, including a rule indicating that a secure data element is to be used to authenticate the payment card. The process also includes receiving payment account details for a payment account associated with the payment card. A payment authorization request message is transmitted to an interchange network and a card authentication request message is then received from the interchange network. The card authentication request message includes an encrypted instruction, which is transmitted to the secure element payment card. The secure data element is received from the payment card and a card authentication request response message is then transmitted to the interchange network. A payment authorization request response message is then received from the interchange network.

A self-authenticating chip includes first and second memory regions storing, respectively, first and second authentication codes. The second memory region is adapted to be unreadable and unmodifiable by the chip or a chip reader. The chip also includes a comparator for providing an indicator of whether given input matches the second authentication code. The chip also includes an authentication circuit that is operable to read the first authentication code from the first memory region, present the first authentication code to the comparator, and in response to receiving an indicator from the comparator indicating that the first and second authentication codes match, unlock at least one of (i) a communication interface of the chip to allow data to be transmitted therethrough to a chip reader and (ii) a third memory region of the chip to allow data to be read therefrom.

A configuration allowing use of one representative card as various types of cards is achieved. There are provided a memory that stores a representative card ID that is an identifier of a representative card, and a control unit that executes a use process for using a registration card registered is association with the representative card through communication with a reader/writer. The use process for using the registration card is executed under a condition that registration card information associated with the registration card is recorded is a database in association with the representative card. The database is a database managed by a server, and including data where the representative card ID, a user ID, and an ID of the registration card registered in association with the representative card are recorded in association with each other.

The present disclosure provides an electronic badge and a housing for the same. The housing includes: a rear case defining a main board cavity, and formed with a display opening in communication with the main board cavity and a profile card receiving slot located outside the main board cavity; and a front case detachably disposed on the rear case to enclose the profile card receiving slot or both the display opening and the profile card receiving slot, a portion of the front case opposite the profile card receiving slot or both the display opening and the profile card receiving slot being made of a transparent material.

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.

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.
