ctional description
2.1
Touchless identification
The readers are designed for contactless identification of MIFARE data carriers data carriers e.g.
(
ID chipcards). A combination of data carrier and PIN can be used for performing functions via the
keypad.
In order to read a data carrier an electromagnetic field with a frequency of 125 kHz (proX) or 13,56
M
(MIFARE) is transmitted from the reader unit. As soon as a data carrier enters this field, it
Hz
transmits data in the power field" to the reader.
"
The individual code of every data carrier renders it unique.
The transmitted code is prepared in the reader so that the connected controller (
or
evaluation unit
central control unit) can continue the processing e.g. switching and control functions.

Security features
The MIFARE DESFire EV1/EV2 technology is the follower of the MIFARE classic system, however
it has a higher security class.
The MIFARE DESFire EV1/EV2 technology use the common accepted encoding procedure AES
(Advanced Encryption Standard). The current encoding procedure AES of DESFire EV1/EV2
readers uses a 128 bit key.
The encoding procedure AES is known as extremely tap-proof and tamper-resistant. In th USA it is
approved for government documents in the highest security ratings.
2.2.2
Data carriers
To be able to use the encryption AES, MIFARE DESFire EV1/EV2 data carriers are needed.
For further information, refer to our current catalog.
The previous MIFARE classic data carrier can only be used parallel to EV1/EV2 data carriers if the
encryption AES is unused!
Before first use the MIFARE DESFire EV1/EV2 data carriers must be formatted and
initialized.
(Not required for MB-Secure with data carriers 026355 und 026350.)
Therefore a corresponding read-in station is required (see Chapter 8.)
For applications in accordance with VdS Class C / EN Grade 3 / SES Grade 3,
MIFARE DESFire EV1/EV2 data carriers must be used. A combination with
MIFARE classic data carriers is not allowed.
