9. A lock system comprising:
-
a lock unit having a releasable catch for securing an article to be locked, a memory for storing information about an intended destination of the article, and an interface; and
a key unit having an aerial for receiving location determining signals and another interface for communicating with the lock unit;
wherein the other interface on the key unit can be brought into short range communication with the interface on the lock unit to transmit location information from the key unit to the lock unit;
and wherein the lock unit releases the catch only when the lock unit receives location information that matches the intended destination stored in the memory. - View Dependent Claims (10)

11. A lock system comprising:
-
a lock unit having a releasable catch for securing an article to be locked, and a memory for storing information about an intended destination of the article; and
a key unit, wherein the lock unit and key unit are arranged in a proximity less than or equal to 20 meters to cooperate to release the catch when a location determined from location determining signals is the intended destination stored in the memory in the lock unit.

12. A key unit for use with a lock unit, the lock unit having a catch for securing an item and a memory for storing an intended destination of the item, the key unit comprising:
-
an interface for transmitting signals to the lock unit to register the lock and key units together;
a receiver for receiving location determining signals and determining the location of the receiver, wherein when the key unit registers with the lock unit in a proximity less than or equal to 100 meters, the key unit transmits the location determined from the location determining signals to the lock unit using the interface so that the lock unit can compare the location transmitted with the stored in the memory and release the catch when the intended destination matches the location.

13. A lock unit for use with a key unit having a receiver for receiving location determining signals, the lock unit comprising:
-
a catch for securing an article to be locked;
a memory for storing an intended destination of the article; and
an interface for interfacing with the key unit to register the lock unit and key units together for receiving location determining information from the key unit, wherein the lock unit is arranged to release the catch to release the article when the lock unit is registered with the key unit having the location determining information matching the intended destination stored in the memory. - View Dependent Claims (14, 15)

16. A method of operating a locking system comprising a lock unit having a catch for securing an article and a memory for storing the location of an intended destination of the article and a key unit having an aerial for receiving location determining information, the method comprising the steps of:
-
bring the lock unit and the key unit together in close proximity;
establishing a communications link between the lock unit and the key unit;
receiving the location determining information in the key unit;
passing the location determining information to the lock unit through the communication link; and
releasing the catch if the location determining information received in the lock unit matches the location stored in the memory. - View Dependent Claims (17)
