A chip card securing assembly detachably received in a body of an electronic device, the chip card securing assembly includes a tray and a connector. The tray includes a receiving portion and a holding portion. The receiving portion includes a first end and a second end, the second end defines a receive slot. The holding portion extends from the first end and configured to hold a chip card. The connector is received in the receiving portion and exposed from the receive slot. An electronic device applying the chip card securing assembly is also provided.

Systems and methods for pairing a payment object reader with a computing device are described. An example method includes detecting, by a computing device and while in a pairing mode, a plurality of payment object readers. Each of the plurality of payment object readers is configurable to be paired wirelessly with the computing device. Each of the plurality of payment object readers outputs a signal strength representative of a location of the payment object reader relative to the computing device. The computing device tracks respective signal strengths of the plurality of payment object readers over time. Based on a determination that a change in a signal strength of a particular payment object reader of the plurality of payment object readers represents movement of the particular payment object reader relative to the computing device, a wireless communication channel is established between the particular payment object reader and the computing device.

The present invention relates to a SIM multiplexing device that provides a mechanism for multiplexing multiple SIM cards into a single SIM device. The SIM Mux device interfaces to the host device via the host device's standard SIM slot. The SIM Mux application resides on the SIM Mux logic device and communicates with the device over the SIM slot's SIM I/O line using standard ISO-7816 messages. The SIM Mux application allows a user to select the active SIM slot via a SIM application interface and directs the logic device which SIM socket to activate on the shared SIM I/O line, thus enabling the user to utilize any one of the populated SIM cards at one time.

Electronic devices are provided with ejectable component assemblies that can be substantially flush with the external surfaces of the housings of the devices, despite variations in their manufacture. The ejectable component assemblies may include connectors coupled to circuit boards of the devices, and trays that can be loaded with removable modules, inserted through openings in the housings of the devices, and into the connectors for functionally aligning the removable modules with the circuit boards. The ejectable component assemblies may also include ejectors coupled to the housings of the devices for ejecting the trays from the connectors and, thus, from the devices themselves.

An interface display method, a communication terminal and a computer storage medium. The interface display method comprises: detecting the number of SIM card(s) in a terminal; and according to the number of the SIM card(s), determining a display interface of the terminal.

Various embodiments are generally directed to techniques to enable use of a transaction card of a user device to perform transactions. Embodiments may include method, techniques, and circuitry to cause a transaction card to extend from a user device to be used to perform the transactions. Further, the transaction card may retract into the housing the user device when not in use.

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.
