  • Patent number: 9916575
    Abstract: A method for wireless communication is described. The method includes using a routing table for multiple secure elements. The routing table assigns a preferred secure element for a transaction type. The method also includes selecting a first secure element for a transaction based on the routing table. The method further includes updating the routing table based on a received command to use a second secure element to complete the transaction.

  • Patent number: 9826364
    Abstract: A method for wireless communication by a wireless communication device is described. The method includes receiving geographic location information. The method also includes querying a geographic location tuning database for tuning parameter values corresponding with the geographic location information. The method further includes determining one or more tuning parameters to change based on the tuning parameter values. The method additionally includes adjusting an antenna for inductively coupled communication with a reader device according to the determined tuning parameters.

  • Publication number: 20170207659
    Abstract: An apparatus for wirelessly transmitting charging power is provided. The apparatus comprises a transmit coil configured to generate a wireless charging field for wirelessly transmitting charging power when driven by a current. The apparatus comprises a control circuit configured to cause the transmit coil to transmit a packet via the wireless charging field, wherein the packet comprises information indicative of the presence of the wireless charging field to cause a chargeable device to electrically disconnect a communication circuit from a receive coil within the chargeable device. The control circuit is further configured to cause the transmit coil to transmit the packet periodically based on a predetermined interval. The predetermined interval has a shorter duration than a duration of a communication interval of the communication circuit. The control circuit is further configured to reduce a magnitude of a strength of the wireless charging field during packet transmission.

  • Patent number: 9647802
    Abstract: A method includes counting a number of successive information frame (I-frame) retransmissions due to a guard timer expiring. A contactless front-end (CLF) transmits the I-frame to a secure element (SE) over a single wire protocol (SWP) interface. The method also includes discontinuing I-frame retransmission when the count equals a retransmission threshold. The method further includes deactivating the SWP interface.

  • Patent number: 9554331
    Abstract: Aspects disclosed herein relate to activating a single wire protocol (SWP) interface with a circuit card. A single wire protocol (SWP) activation procedure is initiated with a circuit card. During the SWP activation procedure, an unexpected frame may be received, and a different SWP activation procedure may be initiated with the circuit card based at least in part on receiving the unexpected frame during the SWP activation procedure.

  • Patent number: 9400888
    Abstract: A method of communicating with a secure element (SE) is described. The method includes transmitting successive RSET frames from a single wire protocol (SWP) interface to an SE, the successive RSET frames including RSET frame retransmissions. The method also includes counting a number of successive RSET frame retransmissions due to a timer expiring. The method further includes generating a firmware interrupt in response to determining that the count has reached a threshold. The method additionally includes deactivating the SWP interface based on the firmware interrupt.

  • Publication number: 20160174267
    Abstract: Various aspects are described herein in connection with methods and/or apparatuses of near-field communication. For example, various methods and apparatuses include an NFC transmitter configured to send a communication establishment (CES) command. The CES command includes at least one transmitter communication enhancement (TX CEN) parameter comprising an operation setting based on a geographic location of the NFC transmitter. The NFC transmitter is configured to determine whether a CES response was received from an NFC receiver and adjust a communications channel based on at least one receiver (RX) CEN parameter included in the CES response based on the at least one TX CEN parameter. Various methods and apparatuses also include a NFC receiver configured to receive a CES command from an NFC transmitter and send a CES response. The CES response includes at least one RX CEN parameter comprising an operation setting based on a geographic location of the NFC receiver.
