Encrypted contactless key fob for keypad
Key fobs sold in packs of 3, 10 or 100 devices
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.

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. Tag key fobs are equipped with DESFire® chips. We compared them to the chips used in most access systems around the world.
Chip EM-Marin MIFARE ® Classic ® MIFARE ® DESFire ®
Use Simple access systems: barriers, intercoms, hotel rooms.
Combined access systems, where additional information is stored on the chip: fitness
Systems with multi-level access in government, international and military institutions
Encryption No Crypto-1 stream cipher with a key size of 48 bits.
A number of studies have shown the possibility of hacking this cipher with tools that are freely available.
Triple DES encryption and AES hardware encryption with 128-bit key.
It will take several supercomputers andmillions of years to hack.
Memory No built-in memory Up to 4 KB of built-in memory, which allows you to store
data on payment, card expiration date, users.
Up to 8 KB built-in memory that allows you to store user data and access keys to multiple security systems.
One key for home and office One Tag can be connected to 13 hubs
