Keyscan iCLASS offers customers a multiple layer of card-to-reader security. End users receive a high-security credential that is exclusive to Keyscan Access Control Systems and backward compatible with legacy iCLASS SE readers. Keyscan iCLASS credentials and Readers are ‘factory programmed’ to match. As a result, only matching cards and readers will work together, further prohibiting other cards and readers from inadvertently functioning within your company's secured areas.
