5.5 mifare® ProX
mifare® ProX tags have an operating system onboard. Data organization depends on
the operating system installed on the card. These cards can include additional
functionalities such as DES or a proprietary encipher algorithm.
Before accessing the operating system, the card must be selected. Customized
commands are issued using the transfer command.
ACG Identification Technologies GmbH 20
ACG HF Multi ISO RFID Reader V1.0
5.6 mifare® DESFire
This tag supports additional security algorithms (DES, Triple-DES, MAC) for security
sensitive applications.
DESFire tags are addressed using a specific command set (see DESFire command
set).
5.6.1 Memory organization
The memory of a DESFire card can be personalized to specific requirements. The
card can be seen as data storage device like a hard disk in a PC. The memory is
divided into a maximum of 28 different applications (directories) with 16 files each. An
application has up to 14 keys. Depending on keys and access conditions a file can
be accessed in four different ways. Plain data is never secured. Data is secured
using a MAC, single DES or triple DES enciphers.
The following figure describes the memory organization of a DESFire card.

5.6.2.1 Activate PICC
Before accessing a DESFire card, the card must be selected. A DESFire card has a
7 byte UID. After activation, the card is powered up and ready to accept a DESFire
command. Application 0 is selected automatically.
5.6.2.2 Select application
To jump into another application, the application has to be selected. An application
can be seen as a directory, which contains up to 16 files. The size of the application
depends on the stored files.
5.6.2.3 Login to application
Specific access rights can be set for each application. Login to an application allows
changing the organization of the application. Login to a file opens a secured file for
access. A file can be accessed in four different ways: without any security or secured
with MAC, single DES or triple DES.
5.6.2.4 Select file
Before accessing a file, the file must be selected
5.6.2.5 Change file
A selected file can be changed according its access rights. If a file is secured, a login
is required before changes can be made.
5.6.2.6 Commit / Abort transaction
Value files, backup files, linear record files and cyclic record files only adapt their
values after the commit transaction command is given. Several files can be changed
within an application at the same time. The abort transactions command annuls all
changes within an application. Power loss will cancel all modifications too.
For more details about application settings and access rights refer to [2].

The reader can communicate with ISO15693 tags. An anti-collision is needed if
multiple instances of tags are in the same antenna field. The reader detects each
type of ISO15693 labels and handles them individually
7.1 Coding of UID
The UID of a tag is defined in ISO/IEC 15693-3. All tags compliant to ISO15693
support the specified format. The UID is factory programmed and cannot be
changed. The UID is needed for the anti-collision sequence to separate several tags
in the same antenna field.

12 Software
By default, data is transmitted at 9600, n, 8, 1, no handshaking. Two protocol modes
are supported. The protocol mode is configured in the reader EEPROM. As factory
default, the ASCII protocol is used.
12.1 ASCII Protocol
This protocol is designed for easy handling. The commands are issued using a
terminal program. Data is transmitted as ASCII hexadecimal that can be displayed on
any terminal program (i.e. HyperTerminal).
Command Data
Variable length Variable length
Figure 12-1: ASCII protocol frame
12.2 Binary Protocol
This protocol is designed for industrial applications with synchronization and frame
checking. An addressing byte for party line (master/slave, multi-drop) is also
included.
The protocol usually requires a device driver. Data is transmitted in binary mode. The
reader uses an internal binary watchdog timer to ensure correct framing.
STX Station ID
1 byte 1 byte 1 byte Variable length 1 byte 1 byte
The binary frame version 2 is only sent to the host. It is implemented to give
extended information to the host.
Version 2 must be enabled in the Protocol configuration 2 register.

12.2.3 Length
Length defines the length of the data block, including the flag byte, if binary protocol
version 2 is activated.
If length is set to zero, 256 data bytes are transmitted. The reader module only can
send 256 data bytes, but cannot receive commands with 256 bytes.

12.3 Register Set
The reader has several system flags used for customization purposes. The flags are
stored in its non-volatile EEPROM. The reader accepts changes to these settings
only during the start-up phase. Clearing all RFU bits is recommended in order to
guarantee compatibility with future releases.
The reader can store up to 32 authentication keys internally to login standard mifare®
cards. An additional 32 keys can be stored for DESFire authentication. All keys are
read only and cannot be accessed via the interface lines.

12.4.3.2 Continuous Read
The reader device reads and displays serial numbers continuously while one or more
tags remain in the field. This command stops if any character is sent to the reader
module. The reader module returns the character ‘S’ (53h).
The reader supports different tag types at the same time. To increase the reading
performance switch to a single tag mode. If more than one tag of the same type
should be detected at the same time, the Multitag flag must be activated. The
response data length depends on the tag type.

Answer
Answer Description
Data Serial number (n bytes)
'N' Error: No Tag in the field (only binary protocol)
12.4.3.2.1 Multitag continuous read mode
If the Multitag flag is set in the Protocol Configuration (PCON) register the reader
reads multiple tags continuously.
12.4.3.2.2 Auto start
The continuous read mode is started automatically in ASCII mode. The auto start flag
must be set in the PCON register.
12.4.3.2.3 Noisy Environment
If the Noisy Environment flag is set, the continuous read mode can only be aborted
with the '.' character.
This is only valid in ASCII mode.
12.4.3.2.4 Binary mode
This command is fully supported in binary protocol mode except the test continuous
read command and the noisy environment flag.
Do not use this command on bus system environment in binary mode, because the
continuous read mode will take possession of the bus system.
12.4.3.2.5 Simple access control applications
Serial numbers are always sent plain. Data encryption is activated after a successful

12.4.3.5.2 Binary Protocol Version 2
This command never sends version 2 binary frames.
12.4.3.6 High speed select
This command selects a card in the antenna field (according to the selection criteria)
or prepares a multiselect command, switches to high baud rates and enables 256byte frames. If execution is successful, the command returns the UID of the selected
card and the used baud rate. The reader automatically detects the maximum frame
size of the card. The reader also tries to communicate to the transponder with the
specified baud rate. If no communication is possible, the reader will automatically
decrease the speed to the next lower value.
This command can also force the reader to the communication speed and frame size
of the tag to the specified values. This is only needed if the high speed select is done
manually with the transfer command.
