The external device of the card reader may be provided between the card reader and the data receiving apparatus. The external device of the card reader and the card reader in the embodiments of the present disclosure automatically transmit data in the memory card to the data receiving apparatus and improve user experience. Moreover, the card reader in the embodiment of the present disclosure can be obtained by improving the existing card reader and external device without increasing too much cost. | 09-27-2012 |
20150201325 | Method and Terminal for Keeping Subscriber Identity Module Card in Standby State - A method and a terminal device for keeping a subscriber identity module card in a standby state are provided. The method for keeping a subscriber identity module card in a standby state includes receiving, by a terminal device, an enabling request, where the enabling request is used for requesting simultaneous standby of a first subscriber identity module card and a second subscriber identity module card; invoking a third-party invocation interface provided by an operating system of the terminal device; performing interaction with a subscriber identity module card control module, so as to complete a network access process of the first subscriber identity module card on the basis of a data file of the first subscriber identity module card; and keeping the first subscriber identity module card and the second subscriber identity module card in a standby state at the same time according to the enabling request. | 07-16-2015 |
20150208239 | METHOD FOR IMPLEMENTING SIM CARD FUNCTION ON TERMINAL, TERMINAL, AND UICC - The present invention discloses a method for implementing a SIM card function on a terminal, a terminal and a UICC. The method includes: downloading information for implementing the SIM card function; writing the information for implementing the SIM card function into a reserved storage space of the terminal; and after the SIM card is activated, authenticating an access identity of a terminal user by using the information for implementing the SIM card function. In the present invention, the information for implementing the SIM card function is downloaded to the terminal, so as to implement the SIM card function by means of software. | 07-23-2015 |
20150215773 | IMPLEMENTATION AND COMMUNICATION METHODS, APPARATUS AND SYSTEM OF VIRTUAL SUBSCRIBER IDENTITY MODULE - The present invention provides implementation and communication methods, an apparatus and a system of a virtual subscriber identity module. The implementation method includes: receiving a VSIM application request sent by a terminal, where the VSIM application request carries an identifier of a VSIM desired by the terminal; obtaining corresponding VSIM installation information according to the identifier of the desired VSIM; and sending the VSIM installation information to the terminal, so that the terminal installs the VSIM according to the VSIM installation information. The embodiments of the present invention effectively solve a problem where an existing mobile operator network does not support the VSIM, and provide an effective and convenient operation scheme for an existing domestic or international roaming service. | 07-30-2015 |
