Claims10
A method of securing information being transferred from an information-storing device to a host device, the method comprising:
- providing a port formed in the host device, the port allowing the information-storing device to be inserted into and removed from the host device by a user;
- providing a port cover having a conductor formed therein along a path substantially encompassing an area between spaced edges of the port cover, wherein the port cover is moveable between a first position in which the port cover blocks the port and a second position in which the port cover enables access to the port;
- positioning the port cover over the port and coupling it to the host device so as to block the port and place the port cover in the first position;
- supplying an electric signal to the conductor formed in the port cover;
- and
- monitoring the electric signal to ensure that the port cover is correctly placed in the first position.

An apparatus for use with a smart card, the apparatus comprising:
- a host device capable of accessing information stored in the smart card, the host device including a housing having a port formed therein, the port allowing the smart card to be inserted into and removed from the host device by a user, wherein when the smart card is inserted into the port, information can be transferred from the smart card to the host device;
- a port cover removably coupled to the housing surrounding the port, wherein the port cover is adapted to be moveable back and forth between a first position in which the port cover physically blocks the port and a second position in which the port cover does not physically block the port;
- and
- wherein the port cover comprises at least one conductor that is coupled to the host device and is operable for at least one of providing an electromagnetic shield across the port and enabling the host device to detect if the port cover is placed in the first position.
