AJAX TAG CONTACTLESS ENCRYPTED KEY RING FOR KEYBOARDS

Product Overview

The Ajax Tag is an encrypted, commercial-grade contactless RFID key fob engineered for rapid, secure, and user-friendly access management across Ajax intrusion alarm systems. Built specifically for use with Ajax KeyPad Plus, KeyPad TouchScreen, and KeyPad Fibra, Tag eliminates the everyday hassles of alarm systems: users never need to remember complex alphanumeric passcodes, navigate mobile smartphone menus, or create dedicated user accounts. Arming or disarming the system is as simple as holding the Tag against the reader on the keypad's front face.

To safeguard against modern electronic skimming, eavesdropping, and credential duplication, Tag utilizes MIFARE® DESFire® (EV1 / EV2) contactless technology complying with ISO/IEC 14443-A standards. DESFire represents the gold standard in secure access control—the same technology used in European transit ticketing systems and high-security enterprise installations—featuring hardware-level 128-bit AES encryption and a triple-pass mutual authentication process that makes cloning or capturing data mathematically unfeasible. Administrators maintain granular control via the Ajax smartphone app: each Tag can be assigned to a specific user name or configured as an anonymous guest pass with restricted access to designated security groups (partitions). If a key ring is misplaced or stolen, an administrator can instantly revoke its access permissions directly from the app without rekeying hardware or changing codes. With support for up to 13 distinct Ajax hubs, a single Tag can unlock an office, residential home, storage warehouse, and holiday cottage.
