Encrypted DESFire credentials for Ajax KeyPad Plus, supplied 3 to a pack. Each one carries Triple DES and 128-bit AES hardware encryption, so it cannot be cloned by holding a reader near someone's pocket the way a 125 kHz proximity card can.
Built for the installer
Each credential is assigned to a named user in the Ajax app, with its own access permissions, so the event log records who armed or disarmed rather than that a card was used. Losing one means disabling that credential, not reissuing the site.
One credential can be paired with up to 13 hubs simultaneously, which is genuinely useful for a key holder or an engineer covering multiple properties on one card.
Pass cards and Tag fobs are functionally identical and differ only in form factor, so choose on what the user will actually carry.
Key features
- Triple DES and 128-bit AES hardware encryption, not a clonable proximity credential

System requirements
