An operating method for a credit card, the method comprising: step S1, a microprocessor is powered on to perform system initialization; step S2, the microprocessor hibernates and is awakened when a preset interruption is detected so as to execute step S3; and step S3, the microprocessor executes preset interruption processing by entering a preset interruption processing flow, and exits the preset interruption processing flow when the preset interruption processing is finished, then returns to step S2. Alternatively, the method comprises: step s1, the microprocessor is powered on to perform system initialization; step s2, the microprocessor checks whether a preset interruption marker is set, and if so, the preset interruption marker is reset so as to execute the preset interruption processing, otherwise the microprocessor executes step s3; and step s3, the microprocessor hibernates, is awakened when detecting the preset interruption so as to set the preset interruption marker, and then returns to step s2. The present invention may reduce the risk of credit card fraud.

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.

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.

A multi-function transaction card may include a card body having dimensions that are in accordance with a standard for transaction cards, an output device on the card body, and a secure element within the card body. The multi-function transaction card may pair, via a wireless connection, the multi-function transaction card with a terminal. The multi-function transaction card may receive, from the terminal, information associated with a transaction. The multi-function transaction card may generate, based on the information associated with the transaction, and using a cryptographic key, an authorization request cryptogram (ARQC), wherein the cryptographic key is stored in the secure element. The multi-function transaction card may generate, based on the ARQC, a machine-readable code. The multi-function transaction card may display, using the output device, the machine-readable code.

An information processing device includes a display control unit that, when at least one NFC antenna has performed close-range wireless communication, effects a display of a communication prompter image that indicates the position of an NFC antenna which is different from the at least one NFC antenna and that prompts for close-range wireless communication with the different NFC antenna.

An electronic card includes: a plate type card plate; a secure element embedded in the plate type card plate and for storing a plurality of application programs linked with a payment means; a control unit for identifying one of the plurality of application programs on the basis of a selection signal received through a selection unit formed on the card plate to generate information for activating the payment means; and a display unit for displaying information for identifying the payment means on the basis of the information for activating the payment means. The control unit manages the identified application program on the basis of the selection signal as a selected application program to generate the information for activating the payment means, by mapping the selection signal on the basis of information about the plurality of application programs provided from the secure element and storing the same, and the secure element receives the information for activating the payment means from the control unit and activates the selected application program when a payment attempt is made from the outside.

A service processing method includes receiving, by a mobile phone, a first identifier from a head device of a vehicle after the head device receives a trigger request to perform a vehicle door opening service, determining, by the mobile phone based on the first identifier, to perform authentication, indicating, by the mobile phone, the head device to perform the vehicle door opening service when the authentication succeeds, or determining, by the mobile phone based on the first identifier, not to perform the authentication, and sending, by the mobile phone, location information of the mobile phone, and an indication that indicating a location of the mobile phone and a location of the head device are normal to the head device.

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 the card. 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.

Wait times at self-service kiosks may undermine the utility of these self-service machines. Self-service kiosks are configured to provide faster self-service kiosks that allow users to quickly perform common financial transactions. However, it has been increasing common for users to have to wait on a line to access a kiosk. Apparatus and methods are provided for a smart card that stages transactions by capturing the amount, pin and other necessary information on the smart card itself, before the user begins interacting with the kiosk. Information captured by the smart card may be transferred to the kiosk when the smart card is inserted into the kiosk. The user does not provide the kiosk with any additional information after inserted the smart card into the kiosk, thereby improving the transaction processing efficiency of the kiosk and enhancing user satisfaction.
