Abstract

A memory card compatible token includes a host interface, radio circuits to transmit signals and a controller to determine if the memory card access commands are for contactless devices attached to the memory card slot or general memory. User payment account information is stored in the contactless chip as part of the contactless devices. The radio circuits can be activated and deactivated by the user for signal transmission using the controller through a mobile computing device.

Claims

1. A memory card token comprising:

a host interface that allows the memory card token to be accepted in a memory card slot;

a radio circuit to transmit signals; and

a controller coupled between the host interface and the radio circuit, wherein the controller is configured to determine if memory card compatible commands received over the host interface are meant to enable and disable an antenna connected to the radio circuit in response to the memory card compatible commands.

2. The memory card token of claim 1 wherein the controller is further configured to maintain financial account information.

3. The memory card token of claim 1 wherein the controller is configured to compare a data field of the memory card compatible commands to a hidden command data value that identifies the commands as non-memory commands.

4. The memory card compatible token of claim 3 wherein the controller is further configured to compare an address field of the memory card compatible commands to an address value that identifies the commands as non-memory commands.
