By presenting a DESFire card or tag for the DESFire reader, a door can easily be opened. This can be done through one of the outputs of the UNii control panel, UNii I / O module and / or UNii card reader interface.
Desfire = Safety
DESFire EV2 is the latest generation of reading technology, which is why Alphatronics has integrated it into the control panel and the card reader. The card or tag is provided with a secure application and thus meets the high security requirements of these systems.
The UNii reads DESFire EV2 from a tag or card, so it is not possible to simply copy the tag or card, as is the case with proximity or some forms of Mifare.
The application that reads the UNii tag or card is equipped with security keys, so the application can only be read and written by a device that recognizes and can decode the keys.
An application can be compared to a file and has its own ID (file name). This file can contain a number of bytes of data. The file contains a unique tag code in the UNii application. This code is used in the UNii to recognize and verify the tag or card.
