The Alarm.com ADC-AC-CARD-50L4 is a 25-pack of ISO EV3 4KB smart card credentials for Alarm.com access control systems. Each card carries an Alarm.com-specific encryption key that can only be read by Alarm.com card readers, providing secure, cloud-managed entry for offices, multi-tenant buildings, and commercial facilities.

Credentials are managed directly from the Alarm.com app, letting administrators add or revoke users, set flexible access schedules, and monitor entry activity without visiting the door. Slot punch marks support both vertical and horizontal badge mounting.
