Patent ID: 8798688

Claim:
A data exchange system for a user to control the exchange of data with a host device comprising host memory, a host transceiver system, and a host antenna, comprising: a device memory module for storing data; a device transceiver system comprising a device transceiver module and a device antenna, where the transceiver system allows the transfer of data between the device memory module and the host memory using the device antenna, the host antenna, and the host transceiver system; a power manager; a first switch operable by the user in a first state and a second state; and a power supply for providing power to the device memory module, the device transceiver, and the power manager; whereby when the first switch is in its first state, the device memory module and the device transceiver do not consume sufficient power from the power supply to allow the transfer of data between the device memory module and the host memory; and when the first switch is in its second state, the device memory and the device transceiver consume sufficient power from the power supply to allow the transfer of data between the device memory module and the host memory using the host transceiver system.
