The Ajax Pass is a contactless secure card designed to provide a convenient way to arm and disarm your security system. Using DESFire® technology and the ISO 14443-A standard, it allows you to manage access without needing to remember a code, making it a practical choice for users who prefer a physical key. To ensure your home remains safe, the card employs Triple DES and AES hardware encryption with a 128-bit key, which protects against signal interception and unauthorized duplication. Each white card is compact and lightweight, measuring 86 x 54 x 0.8 mm and weighing only 6 g, so it fits easily into any wallet. You can assign specific names and access permissions to each card through the Ajax app and link a single pass to up to 13 different hubs. These cards are built to operate reliably in temperatures ranging from -10°C to +40°C and are fully compatible with the KeyPad Plus, providing a seamless entry experience for you and your guests.
