1. A method involving a communication device, comprising:
- detecting a physical proximity of the communication device over a near field communication path existing between the communication device and a local device;
in response to the detecting, transmitting at least one data set to the communication device over a first communication path that traverses a packet-switched network;
sending a request to the communication device over the near field communication path;
receiving a response from the communication device over the near field communication path;
deriving a received data set from said response;
validating the response based on the received data set and the at least one previously transmitted data set previously transmitted to the communication device over the first communication path;
the first communication path existing between a control server and the communication device, and a second communication path existing between the local device and a processing device.

Abstract
A method involving a communication device, which comprises sending a request to a communication device; receiving a response from the communication device over a local communication path; deriving a received data set from said response; determining at least one data set that had been previously transmitted to the communication device over a wireless portion of a second communication path different from the local communication path; and validating the response based on the received data set and the at least one previously transmitted data set.

17. A non-transitory computer-readable storage medium comprising a set of instructions for execution by a processing device comprising a processor:
-
where execution of the set of instructions by the processing device causes the processing device to execute a method comprising validating a response received from a communication device over a near field communication path existing between the communication device and a local device, the response having been sent over the near field communication path by the communication device in response to a request sent thereto over the near field communication path, the method further comprising; deriving a received data set from the response; determining at least one data set that had been previously transmitted to the communication device over a first communication path traversing a packet-switched network in response to detecting a physical proximity of the communication device over the near field communication path, the first communication path existing between a control server and the communication device; and validating the response based on the received data set and the at least one previously transmitted data set; a second communication path existing between the local device and the processing device. - View Dependent Claims (18)

19. A system, comprising:
-
a control server configured to generate at least one particular data set and transmit the at least one articular data set to a communication device over a first communication path that traverses a packet-switched network in response to detecting a physical proximity of the communication device over a near field communication path, the first communication path existing between the control server and the communication device; a local device comprising transmit/receive equipment configured to send a request to the communication device over the near field communication path and to obtain a response from the communication device over the near field communication path, the near field communication path existing between the communication device and the local device; and a processing device comprising a processor communicatively coupled both to the local device over a second communication path and to the control server, the processing device configured to derive a received data set from the response and to validate the response based on the received data set and the at least one particular data set. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
