• An electronic seal design to supersede metal or plastic seals used on lorries to prevent pilferage has helped Caerleon, Gwent, based Encrypta Electronics to win second place in the manufacturers' category of the Design Against Crime competition sponsored by the British Security Industry Association.
The Crypta II seal is bolted on to the back of a lorry. A metal hasp fixed to the unit is fed through the door handle; the other end of the hasp fits into the unit and is held by a rotating knob.
This action causes a four digit, random number to be generated in the unit and retained. So at any time the driver can check whether the door has been opened.
Although the alternative plastic seals cost only a few pence each, they can be used only once and must be kept in a secure place.
Large fleet operators using the electronic seals include Safeway and Tesco.
The other unit that helped to win Encrypta this award is the MicroSeal (miniaturised to around the size of a packet of cigarettes) recording the time and date of each closure. They are used on anything from briefcases to vehicle cash boxes to refrigerated stores. Unisto AG is to market this device worldwide under the name Unisto-Microseal.
Grade 2 acceptance by the Customs, says the company, means it can be used to provide the highest level of indicative sealing for distilleries, revenue goods in transit, meat exports and local import and export control. For further information, circle reader's reply turbocard No 61.
