The A22K is our 3rd generation of ATRIUM, featuring high levels of encryption and flexibility. The A22K brings high security from enterprise-level installations to the mid-market. The A22K can manage traditional readers and cards as well as offer superior support with the latest high security credentials featuring AES128 bit encryption. Paired with the CDVI K2 series of readers (MIFARE, DESFire EV2 credentials) it provides users with full end-to-end encryption between card-reader-controller and the wider ATRIUM network to ensure cards cannot be cloned and systems cannot be manipulated.
