  • Advanced routing mechanisms for secure elements
    Patent number: 9960812
    Abstract: Various aspects are described herein in connection with a method and/or apparatus of near-field communication (NFC). For example, various methods and apparatuses include a NFC controller receiving a current message from a NFC reader. Methods and apparatuses include the NFC controller determining that the current message received from the NFC reader is not associated with a known secure element identification, identifying a secure element corresponding to a last response message sent to the NFC reader, and sending the current message to the identified secure element that originated the last response message sent to the NFC reader. Methods and apparatuses also include the NFC controller receiving a request message from the NFC reader prior to the receiving of the current message, receiving the last response message from one of a plurality of secure elements, and saving an identification of the one of the secure elements that sent the last response message.
