Quick access to the security system
To disarm the security system, just present Tag to the reader on the keypad. This copy-protected key fob allows you to manage security modes without a password, user account and access to the Ajax app.
Tag is supported by KeyPad Plus
Top-tier data protection
To identify users quickly and securely, KeyPad Plus features the DESFire® technology. It is the best-in-class contactless solution to identify the user by card or key fob.
DESFire® is based on the ISO 14443 international standard and combines comprehensive 128-bit encryption and copy protection. This technology is also used in transportation systems of European capitals and access systems at NASA.
One key for home and office
One Tag can be connected to 13 hubs
Full control in the app
In the app, you can set the name and access permissions for each key fob. You always know who and when changed the security mode — every action is recorded in the event log.
A system administrator can revoke or restrict Tag access permissions in real time.
Effortless connection
To add Tag to the system, all you need is to open the Ajax app, go into the settings and present the key fob to the keypad.
