Proven history of secure solutions

Advanced Physical Access Control Readers and Cards

deister were an early pioneer of developing and manufacturing proximity access control cards and  readers. 30 years ago we invented the technology that allowed blank cards to be programmed on demand, we were the first to deploy card programmers to many of the access control manufacturers and one of the first companies to offer secure proximity access cards that overcame copy attacks of that time. Today, we are independent of any card technology or access control system and globally supply advanced secure readers that are capable of not only reading many different card technologies at the same time but connecting to a wide range of access control systems – The ability to reconfigure many of our readers to suit customers changing requirements provides outstanding long term value.
