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 a 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.

Microchip with smart capabilities

From the user perspective, contactless access works simply. To disarm the system, all you need is to present a card or a key fob to the keypad. But there is an impressive technology behind this simplicity. Pass cards and Tag key fobs are equipped with DESFire® chips. We compared them to the chips used in most access systems around the world.

Outstanding autonomy

The all-new KeyPad Plus firmware gets the most out of the pre-installed batteries. Even with daily use of the contactless identification function, the keypad will work for 3.5 years without replacing batteries. And with the card and key fob reader disabled, the battery life reaches 4.5 years. KeyPad Plus will warn a monitoring station and users in advance about the need to replace the batteries.

Remote access control

Set up personal codes to know who and when disarmed the system: a username is displayed in the notification and in the event log. Pass or Tag can also be assigned to a specific user with defined permissions to control security of specific groups or the entire site. Ajax app allows you to manage access permissions in real time. You can limit, extend, or instantly block access.

Adding users. Fast and easy.

Ajax systems support up to 200 Tag key fobs or Pass cards2. When adding them, you do not need to create Ajax accounts for new users, you just need to name a device and define access permissions. This makes it easier to delegate access to the system control to temporary employees or incoming staff.

Access for unregistered users
KeyPad Plus supports up to 99 keypad access codes5 for people not registered in the Ajax system. Thanks to this feature, there is no need to create accounts for office employees, a cleaning company, or a realtor: it is enough to assign an access code to a person in the hub settings.
