A method, apparatus, system, and signal-bearing medium that, in an embodiment, simulate allocation of a simulated resource to simulated partitions in a simulated logically-partitioned computer and determine whether the allocation conflicts. The method includes steps of storing information about an item under inspection, linking a unique item identifier with the information to uniquely associate the information with the item under inspection and retrieving the information about the item under inspection in response to a request. The present invention for locating and tracking packages and goods transported through aviation can automatically identifies if the device enters the airport to turn off the radio communication function. The third sensor detects tampering with the system.
