A method for determining an association between a bankcard identifier and at least one mobile communications terminal identifier. The method is implemented by an electronic device and includes: obtaining an identifier of a current bankcard, a bankcard used to make a purchase of an article or a service by using a payment terminal, the obtaining being implemented at the time of the execution of a payment transaction made by using the bankcard; at least one step of obtaining a piece of data representative of at least one communications terminal identifier; and computing a score of correspondence between bankcard identifier and the at least one piece of data representative of a communications terminal identifier.

Techniques are described for facilitating sharing of executable software images between users in a configurable manner. In at least some situations, the executable software images are virtual machine images, and while executing may access and use remote network-accessible services (e.g., Web services). In addition, some or all shared executable software images may be made available in a fee-based manner by creator users, such that execution of such a fee-based software image by a software image execution service on behalf of a user other than the creator user is performed in exchange for fees from the other user as specified by the creator user. The creator user may further receive at least some of the specified fees paid by the other user, such as at least some of a difference between the specified fees and fees charged by the software image execution service for the execution.

In accordance with a first aspect of the present disclosure, a method is conceived for providing a digital representation of a transaction card in a mobile device, comprising: detecting, by a near field communication unit of said mobile device, that the transaction card is in proximity of the mobile device; upon or after said detecting, performing, by a processing unit of said mobile device, the following steps: retrieving the digital representation of the transaction card from a digitization server; loading the digital representation of the transaction card into a memory of the mobile device; activating the digital representation of the transaction card for a predefined validity period; invalidating the digital representation of the transaction card if no successful near field communication transaction has been performed within said validity period. In accordance with other aspects of the present disclosure, a corresponding computer program and a corresponding mobile device are provided.

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 touch sensor layer, a display layer (including, for example, LEDs, a dot matrix display, and the like), a microcontroller storing firmware, Java applets, Java applet integration, and the like, an EMV chip, 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. The card includes a secure element to receive visual impairment settings and alert data. A microprocessor can convert the alert data into impairment data based on the visual impairment settings. A display is generated based on the impairment data.

According to some embodiments, a method comprises: storing, in a personalization token, information to personalize an identification token; issuing the personalization token to an account holder; and transmitting the information from the personalization token to the identification token using a wireless interface. According to some embodiments, apparatus comprises: a personalization token issued to an account holder, the personalization token comprising: information to personalize an identification token; and a wireless communication interface to transmit the information to the identification token.

A dynamic transaction card that includes a transaction card having a number of layers, each of which may be interconnected to one another. For example, a dynamic transaction card may include a protective film layer, an outer protective layer, a core layer, a potting layer, a touch sensor layer, a display layer (including, for example, LEDs, a dot matrix display, and the like), a microcontroller storing firmware, Java applets, Java applet integration, and the like, an EMV chip, an energy storage component, one or more antennas (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, which may include a back protective layer. The antennas may be mounted on the protective film layer and connected to the printed circuit board (PCB) using conductive epoxies.

The present invention relates to a method and a system for inscribing and securely storing cryptographic keys on a physical medium, and to a corresponding physical medium, comprising the following steps: from a first management entity (31), generating (1) a first pair of asymmetric cryptographic keys comprising a first user public key (pub1) and a first user private key (priv1), inscribing (2) the first user private key (priv1) onto a physical medium, and affixing (4) a first tamper-evident concealing element (hol1) to the physical medium in order to conceal the first user private key (priv1) and seal same, said first user private key (priv1) being accessible only by visibly breaking said first tamper-evident concealing element (hol1); from the second management entity (32), generating (6) a second pair of asymmetric cryptographic keys comprising a second user public key (pub2) and a second user private key (priv2), inscribing (7) the second user private key (priv2) onto the physical medium and affixing (9) a second tamper-evident concealing element (hol2) to the physical medium in order to conceal the second user private key (priv2) and seal same, said second user private key (priv2) being accessible only by visibly breaking said second tamper-evident concealing element (hol2); generating (10) at least one last user public key (pub0) and/or at least one cryptographic address (adr, adr-mult) from the first user public key (pub1) and the second user public key (pub2), inscribing (11) said at least one last public user key (pub0) and/or said at least one cryptographic address (adr, adr-mult) onto the physical medium, and verifying (12, 13) same, and finally recovering the private keys (priv1, priv2) comprising the generation of a last user private key (priv0) corresponding to the last user public key (pub0) and/or to said at least one cryptographic address (adr, adr-mult).

Example embodiments of systems and methods for data transmission system between transmitting and receiving devices are provided. In an embodiment, each of the transmitting and receiving devices can contain a master key. The transmitting device can generate a diversified key using the master key, protect a counter value and encrypt data prior to transmitting to the receiving device, which can generate the diversified key based on the master key and can decrypt the data and validate the protected counter value using the diversified key.

Described herein is a system for automatically reissuing a prepaid device for an expired account upon detecting a funding event associated with the expired account. An account may be expired upon determining that one or more expiration conditions have been met. An event handler may be configured to receive events. Upon identifying a funding event associated with an expired account, the event handler may initiate a reissuance process for a prepaid device associated with the account.
