A computer-implemented method includes identifying critical data on a primary storage of a mobile device, where the primary storage is powered by a primary battery component. The critical data is backed up from the primary storage to a secondary storage. A charge level of the primary battery component is detected. It is determined that the charge level of the primary battery component is less than a minimum threshold. The mobile device is switched from a primary mode to a secondary mode, based on the charge level being less than the minimum threshold. A secondary battery component powers the secondary storage in the secondary mode, and the critical data is accessible on the secondary storage in the secondary mode.

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 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 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.

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.

In some implementations, a system is capable of generating identifications that include distinctive line patterns corresponding to different portions of secure customer information. Data indicating an input image, and a dithering matrix representing a two-dimensional array of pixel values is obtained. Pixel values of pixels included in the input image are transformed using the dithering matrix. For each pixel within the input image, the transformation includes identifying a particular pixel value within the dithering matrix that represents a particular pixel within the input image, and adjusting an intensity value of the particular pixel based on attributes of the dithering matrix. A transformed image is generated based on the transformation and then provided for output.

The mechanically stable value or security document 2000 according to the invention comprising an electric circuit 1270 is characterised by the following features: the document is formed of at least three document layers which are arranged in a stack 1700 and which are connected together face-to-face by a joining method, wherein a first document layer is formed by a circuit carrier layer 1200 which supports the electric circuit 1270, at least one second document layer is formed in each case by a compensation layer 1100 which has at least one opening 1120 and/or recess, and at least one third document layer is formed in each case by an outer cover layer 1300. The first 1200, the at least one second 1100, and the at least one third document layer 1300 are formed from a fibre composite material.

A multi-functional authentication apparatus and an operation method for the same are provided. The multi-functional authentication apparatus integrates multiple communication modules into one device. A biometric authentication procedure is firstly performed when activating this multi-functional authentication apparatus. A security code is generated through a security authentication mechanism provided by this apparatus after reading biometric features. After that, according to a connection protocol, one of the communication modules of the multi-functional authentication apparatus is activated to connect with an external host. The security code is transmitted to the host via the communication module for identifying a user. The multi-functional authentication apparatus acts as an authenticator that allows a user to login to a computer system or obtain a network service after authentication. The multi-functional authentication apparatus also provides authentication for the user to open an access control device or conduct a mobile payment.
