Ajax Tag – Contactless Encrypted RFID Key Ring for Keypads (Black)

The Ajax Tag (SKU: 38225.90.BL) is a compact, high-security contactless RFID key fob designed for quick arming and disarming of Ajax security systems without typing access codes or managing smartphone apps. Engineered for family members, office employees, cleaning staff, and temporary personnel, users simply swipe the Tag across a compatible Ajax keypad (such as KeyPad Plus or KeyPad TouchScreen) to instantly change security modes.

Equipped with industry-leading MIFARE® DESFire® EV1 / EV2 encryption, Ajax Tag provides enterprise-grade data protection against skimming, interception, and credential duplication. Each Tag is linked directly to a specific user profile or can operate as a guest pass, recording individual event logs in the Ajax app. Housed in a durable, wear-resistant, and water-resistant casing with an integrated key ring hole, it delivers convenient daily access in a sleek black finish.
