Abstract
A wireless communication device such as a cell phone is rendered temporarily inoperable by enclosing the device in a container such as a heat sealable bag (1) which has been metallized so that when the device (2) is sealed in the container (1) it is surrounded by a metal layer (9) which blocks signals to and from the device (3) to thereby render it inoperable. The device is sealed within the container (1) by a seal such as a heat seal which will reveal any attempt to remove the device from the container.
