Entry key fobs have up to 34 billion different combinations of ID number
Transport police are working with Gwent Police to target a metal theft hot spot in south Wales. The first area to be targeted will be in the Rhymney Valley but the aim is to also expand into Newport. Officers will be dedicated to tackle just metal thefts in that location. Det Insp Mark Cleland, of British Transport Police, said: “We’ve got some British Transport Police officers, some Gwent [Police] officers and we’ve got support from the Environment Agency.”
Contactless key fobs are used to operate an Access Control Wales computer-controlled door entry system. Each fob has a microchip embedded within it that holds a unique factory encoded ID number. With up to 34 billion different combinations of ID number, there is no chance that your key fobs can be duplicated. In addition, each ID number has built-in security and integrity checks ensuring that it cannot be misread. A cross-reference list correlating the external printed fob number and the programmed ID number is also provided.
