Electronic seal to put off grave robbers

To put off modern-day grave robbers, the Cairo Museum turned to British technology. An award-winning electronic seal made by Encrypta Electronics, Gwent, has been installed on the access door to the room that displays the treasures from Egypt’s past. The curse of the lightfingered has been averted with an electronic sealing system which automatically generates a four digit random number every time it is sealed. This is retained in its electronic memory. If you check it one day and the number’s changed, you know it has been opened. The design is the only electronic form of sealing that has HM Customs & Excise Grade II acceptance, which is the highest possible level of security for indicative sealing.
