Various embodiments described herein are directed towards authenticating calls by using one or more keys associated with a specific user. In examples, the user is the sender of a call. In various embodiments, when a call is made, an identifying payload is encrypted using a private key associated with the user. The encrypted identifying payload is appended to the call data stream. The identifying payload may be decrypted with a public key. In embodiments, the identifying payload may be verified. In various embodiments, further authentication methods may be performed by using an object such as a contactless card to provide one or more components of the identifying payload and/or keys. In embodiments, a connection may be made between the sender and the intended recipient of a call based on the verification of the identifying payload.

In accordance with some embodiments, an apparatus for privacy protection is provided. The apparatus includes a housing arranged to hold a personal communication device, a first subscriber identity module (SIM) interface, a second SIM interface, a personal communication device interface, and a controller. A portion of the personal communication device interface is shaped to mate with a SIM slot of the personal communication device, and the personal communication device interface includes a SIM emulator operable to couple the second SIM interface to the SIM slot of the personal communication device. Through operation of the personal communication device interface, the controller is operable to selectively couple one of the first SIM interface and the second SIM interface to the SIM slot of the personal communication device.

A circuit for performing a near-field communication having a contactless circuit which is configured for the contactless exchange of data signals with an external contactless reading device, a security circuit which has a memory in which application identifiers are stored and which is configured to execute security-related applications, and a control circuit which is configured to execute non-security-related applications, wherein the contactless circuit, the security circuit and the control circuit are coupled with one another in such a way and, using at least one of the application identifiers, are configured in such a way that the data signals are supplied from the contactless circuit to the control circuit and vice versa exclusively by means of the security circuit. The security circuit can furthermore store bonding and authentication keys for applications in the control circuit in order to set up a secure data exchange channel for these applications.

The present disclosure relates to a card socket into which a card tray capable of loading a plurality of electronic cards is inserted, a card connector, and a manufacturing method therefor. According to one embodiment of the present disclosure, a card socket is for electrically connecting a card having a terminal unit to an electronic device, the card socket comprising: a conductive shell; a nonconductive middle plate; an upper contact terminal; and a lower housing having a lower contact terminal, wherein the upper contact terminal is integrally coupled to the shell by interposing the middle plate therebetween, and the shell is coupled to the lower housing so as to form, therein, an accommodation space in which at least one card is accommodated.

A card bracket and a terminal are provided. The card bracket is capable of accommodating a data card and is capable of being inserted into a housing of the terminal. The card bracket includes a card tray and a card cover. The card tray is configured to accommodate the data card. The card cover is coupled to the card tray and is rotatable relative to the card tray. The card cover includes a first end and a second end opposite each other, and further includes a first protrusion extending towards the card tray. When the card bracket is in a state of being inserted into the housing and a push force is applied to the first end, the card cover is rotatable about the first protrusion, so that the first end further extends into the housing while the second end extends out of the housing.

A sliding mechanism applicable in a terminal device includes: a sliding plate and a fixed plate arranged in a stacked way, wherein the sliding plate is provided with a slide rail on both sides in a sliding direction; a guide side of the fixed plate is accommodated in the slide rail, enabling the sliding plate to slide along the fixed plate; the guide side is provided with a guide rail protruding toward the slide rail, and the slide rail is provided with an elastic element, the elastic element sliding along the guide rail and being deformed; a gap is provided between the sliding plate and the fixed plate, and position stopping elements are correspondingly arranged on the fixed plate and at least one of the sliding plate or the slide rail, and configured to stop the sliding plate at a starting point and an ending point of sliding.

A system and a method for conducting credit card transactions through a mobile device of a user. The mobile device comprises an image acquisition unit and a mobile application operated by the mobile device. The system enables acquiring an image of a client's credit card, using the image acquisition unit; analyzing data of the image; outputting details of the credit card from the analysis; verifying the output details, wherein the verification is further carried out through the mobile application; verifying authorization of inputted monetary transaction, wherein the mobile application enables verifying the authorization by communicating with the billing center, associated with at least one credit company associated with the credit card over at least one communication network, wherein the communication is carried out by the mobile application using the mobile device; and conducting monetary transactions using the verified credit card details.

Disclosed herein is a mobile phone with the Near Field Communication (NFC) technology and method of operating the mobile phone. The mobile phone includes a display; a baseband chip; a near field communication (NFC) module comprising an RF antenna, an NFC tag circuit and an NFC main chip; and the RF antenna configured to receive incoming RF signals.

A telescopic mechanism includes a mounting base, a telescopic block received within the mounting base, and a pushing rod received within the mounting base. The telescopic block is vertically arranged in the mounting base, and the pushing rod is horizontally arranged in the mounting base. The telescopic block defines a guiding channel. The pushing rod passes through the guiding channel. The pushing rod is driven through the guiding channel to cause the telescopic block to extend or retract relative to the mounting base.

Systems, methods, articles of manufacture, and computer-readable media. A server may receive a phone call and generate a uniform resource locator (URL) comprising a session identifier for an account. The server may transmit the URL to a client device. The server may receive, from a web browser, a request comprising the URL. The server may determine that the session identifier in the URL of the request matches the session identifier for the account, and transmit, to the web browser, a web page at the URL. The server may receive, from the web browser, a cryptogram read by the web page via a card reader of the client device and decrypt the cryptogram. The server may authenticate the identity of the caller for the call based on decrypting the cryptogram and the session identifier of the URL matching the session identifier of the account.
