The multiCLASS family of card readers is designed for customers upgrading their current card system from the most popular proximity technologies to iCLASS credentials. With the RP40, RPK40 and RP15 readers, the customer has the ability to transition to smart cards over time while incorporating the use of multiple card technologies within a single building or across multiple facilities. A proximity reader is part of an overall access control solution that would also include a door controller, door hardware and accessories.
