A memory card compatible token includes non-memory components accessed using commands hidden in the data stream of a memory card access command. A mobile computing device such as a mobile phone accesses the non-memory components by writing to a specific address, including a known data value in the data stream, or both. The token may be activated using an activation code, and a subsequently chosen password may be used to authenticate the mobile computing device to the token each time a hidden command is issued.
