Ajax Systems Tag 100pcs (38225.90.BL)

For installers and security integrators who need a reliable, high-security credential solution, the Ajax Systems Tag 100pcs pack delivers a bulk set of DESFire RFID tags engineered specifically for Ajax KeyPad Plus. Unlike generic 13.56 MHz tags that rely on weaker encryption, these tags use AES-128 encryption and DESFire EV1/EV2/EV3 technology, ensuring that cloning or unauthorized duplication is virtually impossible. The pack includes 100 black tags, each measuring 30 x 30 x 2.7 mm and weighing just 6 g, making them easy to distribute to users while maintaining a professional appearance.

• 100 DESFire RFID tags per pack for multi-user deployments
• Compatible with Ajax KeyPad Plus for arming/disarming
• AES-128 encryption and ISO 14443-4 (DESFire EV1/EV2/EV3) for high security

• Operating temperature range: -25°C to +50°C
• Humidity tolerance up to 95%

In daily use

Each tag functions as a contactless credential: simply present it to the Ajax KeyPad Plus reader to arm or disarm the security system. The tap-and-go interaction is fast and intuitive, reducing friction for employees, family members, or tenants. Because the tags are passive, there is no battery to replace or maintenance schedule to follow. The compact size allows them to be attached to key rings, lanyards, or ID badges without adding bulk. In environments with many users, the 100-piece pack provides a cost-effective way to issue credentials while maintaining a consistent security posture.
