  • Patent number: 9503897
    Abstract: Aspects of various embodiments are directed to the communication of wireless data. In a particular embodiment, an apparatus includes a master/wireless communication circuit and a slave circuit that carries out a secure function. The master generates session initiation commands, and the slave is responsive to these commands by generating and storing a session ID. In response to the receipt and validation of user-input data, the slave accesses and locally stores the session ID. Upon the initiation of and/or during a wireless communication process, the slave again accesses the session ID and compares the accessed session ID with the locally stored session ID, and facilitates communication based on the comparison (e.g., communication is not permitted if the comparison does not indicate a match).
