Systems and methods for transmitting data using near field communications

A method of allowing a user to control the exchange of data with a host device comprising host memory, a host transceiver system, and a host antenna, comprising the steps of:

• providing a device memory module for storing data;
• providing a device transceiver system comprising a device transceiver module and a device antenna, where the device 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
• mounting the device memory module, the device antenna, the device transceiver, a first switch, and a power supply within a housing;
• arranging the housing such that the host antenna and the device antenna are coupled;
• allowing the user to operate the first switch is in its first state such that 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
• allowing the user to operate the second switch is in its second state such that 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.

A data exchange system for allowing 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;
• a power supply for providing power to the device memory module, the device transceiver, and the power manager;
• and
• a housing for containing the device memory module, the device antenna, the device transceiver module, the power manager module, the first switch, and the power supply;
• whereby
• when the first switch is in its first state, the power manager operates in a first mode in which 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 power manager operates in a second mode in which 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.
