|20150178718||SMART CARDS AND SMART CARD COMMUNICATION METHODS AND SYSTEMS - The present disclosure includes a smart card. The smart card includes an audio module to receive a money deduction request in a form of an external audio signal from an external device, wherein the monetary-amount deduction request includes a monetary amount to be deducted and the external device's identification information. The smart card further includes a data processing module to authenticate the external device's identification information, deduct the monetary amount from the smart card after the authentication of the external device's identification information is passed, and generate monetary-amount-deduction result information. The audio module transmits to the external device the monetary-amount-deduction result information in a form of an audio signal, wherein the monetary-amount-deduction result information includes a deducted monetary amount to be added to the external device and the smart card's identification information to be authenticated by the external device.||06-25-2015|
|20140349608||SECURE RF COMMUNICATION METHOD, TERMINAL AND SYSTEM - A method, terminal and secure RF communication system are provided. The method for radio frequency secure communication of the invention comprises: generating magnetic channel data, and transmitting the magnetic channel data via a magnetic channel; establishing a radio frequency link with a peer device which feeds back a response information of the magnetic channel data; generating first radio frequency data, encrypting the first radio frequency data using the magnetic channel data, and transmitting the encrypted first radio frequency data to the peer device via the radio frequency link; and/or receiving encrypted second radio frequency data transmitted by the peer device via the radio frequency link, and decrypting the encrypted second radio frequency data using the magnetic channel data. By the above technical solution, the invention avoids the risk that a preset key is intercepted or decrypted, and enhances the security of the radio frequency link data exchanging process.||11-27-2014|

|20120297210||INTEGRATED CIRCUIT (IC) CARD SYSTEM - An integrated circuit (IC) card is disclosed. The IC card includes a microprocessor and memory module configured to perform a transaction associated with the IC card, and an interface device providing a power input line from an external source. The IC card also includes a power management module coupled between the microprocessor and memory module and the interface device to convert power from the power input line into electric charge, to store the electric charge internally, and to provide power to the microprocessor and memory module when the external source does not provide sufficient power to the IC card.||11-22-2012|
|20120060054||METHOD FOR USING BAD BLOCKS OF FLASH MEMORY - A method is provided for using bad blocks in flash memory. The method includes placing in a replacement area of the flash memory a special bad block that meets a “still usable” condition from the bad blocks of the flash memory. The method also includes receiving a use request for using the special bad block in the replacement area to store user data, writing the user data into the special bad block, and determining whether the user data is successfully written into the special bad block. Further, the method includes placing the special bad block back into the replacement area for a next use request when it is determined that the user data is not successfully written into the special bad block.||03-08-2012|
|20120057701||MOBILE TERMINAL WITH ENCRYPTION CHIP AND RELATED NETWORK LOCKING/UNLOCKING METHOD - A mobile terminal is provided with a network lock functionality for a network. The mobile terminal includes a subscriber identity module (SIM) slot configured to host a SIM card or an unlocking device, a control chip, an encryption chip, and a network locking module. The control chip is coupled to the SIM slot through a first interface, the encryption chip is coupled to the SIM slot through the first interface to communicate with a module inserted into the SIM slot, and the network locking module is coupled to the encryption chip through a second interface. Further, the network locking module is configured to perform the network lock functionality. The network locking module also has an “open” state supporting a network unlocking operational mode and a “close” state supporting a network locking operational mode. In addition, the encryption chip is configured to determine whether the module inserted into the SIM slot is the SIM card or the unlocking device and, when the encryption chip determines that the inserted module is not the unlock device, to set the “open” state or the “close” state of the network locking module to control the mobile terminal to enter in the network unlocking operational mode or the network locking operational mode, respectively.||03-08-2012|
|20110241840||METHOD AND DEVICE FOR IMPROVING COMMUNICATION DISTANCE ACCURACY OF A TRANSACTION SYSTEM VIA TEMPERATURE COMPENSATION - A method for improving communication distance accuracy of a transaction system via temperature compensation includes: storing a reference temperature value and a reference field intensity value in a card read micro-controller (||10-06-2011|
