The invention proposes a method of authentication of an electronic identity device (1) presented by an individual, the method being characterized in that it comprises the implementation of steps of: (b) Reception by data processing means (21) of a server (2) of an acquired image of said electronic identity device (1), the image representing at least one personal visual element of the individual and a dynamic verification code that are visible on said electronic identity device (1), said dynamic verification code containing at least one item of reference information representative of an expected appearance of said visual element; (c) Extraction, by analysis of said acquired image by the data processing means (21) of the server (2), of: an item of candidate information representative of the appearance of said visual element as represented in the acquired image; the reference information representative of the expected appearance of said visual element contained in said dynamic verification code as represented in the acquired image; (d) Verification by the data processing means (21) of the server (2) that the extracted candidate information and reference information match. The invention also relates to a server and an electronic identity device for that purpose.

Universal cards are used in place of all the other traditional cards which a person may want to carry. The universal card can include a short range communications transceiver to communicate with a mobile device. The mobile device can include a user interface and an e-wallet application so that the user can interface with the e-wallet application for programming the universal card via the short range communication link. Once programmed, the universal card emulates a function of a traditional card.

A method includes determining a value amount associated with a transaction card having an optical code. The method also includes, based on a transaction involving the transaction card, updating the value amount. The method also includes determining that the optical code has been read. Responsive to the optical code being read, the method includes causing a display associated with the transaction card to render the value amount.

A method and system for conducting and recording insurance claim transactions using blockchain is provided. The method comprises the steps of: receiving a first verification element from a claimant at an authenticated provider device of a provider; verifying an eligibility of said claimant at a financer and an eligibility of said provider at a provider network according to said first verification element and said provider device; receiving a second verification element from said claimant at said provider device, said second verification element being distinct from said first verification element; conducting said insurance claim transaction by triggering a transaction chaincode at said provider device according to said second verification element; recording an entry of said insurance claim transaction on a blockchain ledger of a blockchain system; wherein a hashed value of an irreversible hash of said first verification element and said second verification element is stored in a global ledger of said blockchain system, and said entry of insurance claim transaction is stored in a private ledger of said blockchain system only accessible by said financer and said provider network; wherein a proof of claim of said insurance claim transaction is collected from said provider device at the time said transaction chaincode is triggered.

A method for querying information in a visual smart card, comprising: a micro control unit receiving, by means of an input device, a query request inputted by a user (S1); the micro control unit determining information queried by a user request according to a received query request (S2); if first information, the micro control unit reading a first information record which is stored thereby, and parsing the first information record to obtain the first information, the first information being displayed by means of a display device (S3); if second information, the micro control unit sending an application selection instruction to a smart card chip, receiving an application selection response returned by the smart card chip, then sending an information record reading instruction to the smart card chip, receiving a second information record returned by the smart card chip, and parsing the second information record to obtain the second information, the second information being displayed by means of the display device (S4). A visual smart card applicable to said method overcomes the shortcomings in the existing technology wherein the assistance of other devices is required, while carrying out querying by means of operating a smart card directly facilitates a holder of a smart card understanding information in the smart card, improving the ease of use of smart cards.

One example of a financial transaction medium includes a passive electronic paper display. A security code is displayed on a portion of the passive electronic paper display.

There are provided systems and methods for dynamically linking machine-readable codes to digital accounts for loading of application data. A user may engage in a transaction with another user, such as a purchase of goods, services, or other items a merchant using a physical payment card. A machine-readable code may be provided on the payment card, where the machine-readable code may be dynamically linked to underlying data with an online transaction processor. The user may provide the payment card to another user that may capture the machine-readable code on the payment card. The other user's device may then utilize the machine-readable code with the online transaction processor to perform an account lookup using database information dynamically linked to the machine-readable code. Thereafter, the other user's device may automatically load account data for the account without having the user enter the account's identifier.

Typically, online transactions, such as online purchases of products or services require entering sensitive transaction information into a third-party web browser or application. This may expose sensitive transaction information to an increased risk of inadvertent disclosure. Apparatus and methods are provided for a smart card which enables users to securely complete online transactions without entering any sensitive transaction information into a third-party system. The smart card may include a microprocessor and wireless interface. The wireless interface may provide wireless communication capabilities and the ability to initiate online payments based on information captured by the touch-sensitive screen. The wireless interface will receive communications from a merchant or issuer bank requesting payment. The microprocessor may be configured to offer multiple selectable payment options to the user.

In certain embodiments, indication-related detectable changes on a transaction token may be facilitated. In some embodiments, a transaction card may determine a state of the transaction card (e.g., during an interaction with a transaction terminal). The transaction card may generate a signal related to a color based on the state of the transaction card and cause the signal to be transmitted to a change element of the transaction card. The change element may be configured such that the change element causes one or more edges or other portions of the transaction card to be (i) a first color in response to the signal being a first signal and (ii) a second color in response to the signal being a second signal. As an example, the portions of the transaction card may turn red when the signal is a first voltage and green when the signal is a second voltage.

This may expose sensitive transaction information to an increased risk of inadvertent disclosure. Apparatus and methods are provided for a smart card which enables users to securely complete online payments without entering any sensitive transaction information into a third-party system. The smart card may include a touch-sensitive screen configured to display selectable payment options. The smart card may include a microprocessor and wireless interface. The wireless interface may provide wireless communication capabilities and the ability to initiate online payments based on information captured by the touch-sensitive screen.
