13,56 MHz Multitag Reader Module, Version 0.9v
1 Scope
The 13,56 MHz Multitag Reader Module is a proximity reading device supporting a
wide range of 13,56 MHz tag. It supports ISO15693, Icode®, Tagit®, Mifare®
Standard, Mifare® Ultralight, SR176 and ISO14443 Type B cards. Using an external
antenna and a serial interface it can be easily connected to a PC. The Plug and Play
version has an integrated antenna and serial interface.
The first part of the documentation described general functions and memory
management of different tags. A listing of the memory map is given in detail if
necessary.
The second part lists the OEM module and describes the pin out.
The next chapter lists all commands and introduce to them. Each command is
explained and an example illustrates the usage. FAQs highlight general issues of the
handling of the 13,56 MHz Multitag Reader Module.
The appendices describes the Plug and Play Module, the custom coil design,
matching circuit and all steps to upgrade the Plug and Play board to +12V supply
voltage.
Additionally the use of the TempeSense® label is high lightened.

Figure 3-1: State Diagram
The state diagram shows the different states of a tag. First the tag must be power up.
Next command initialize a tag using the anticollision or inventory command.
A selection of a tag is necessary to interact with a tag of interest especially if more
than one tag is present at the same time. Only selected tags are capable to response
to higher commands such as read or write page data.
READY state A tag enters the READY state after it receives a
valid inventory or anticollision command. At this
state the tag all serial numbers are known and
the tag is ready to select.
ACTIVE state After a selection the tag is in the ACTIVE state.
Only an activated tag can respond to a read or
write command.
HALT state The HALT command disables a tag for further
communication. The tag is still in the field but
dies not respond to any command. To activate a
tag and to put it back to the Ready state a
WAKE-UP command has to be used.

3.3 ISO 15693
The reader can communicate with ISO15693 tags. An anticollision 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
3.3.1 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 anticollision sequence to separate several tags
in the same antenna field.

3.3.2 Memory organization
An ISO15693 tag is separated into two blocks. An administrative block which
contains the UID, AFI, DSFID and the lock page state. The user block is free for
custom use. The chip manufacturer defines the amount of bytes and number of
pages of each tag. As default four bytes are used for several tags.

3.3.3 My-D Label (SRF55VxxP)
My-D labels are specific labels of Infineon. These labels show a different memory
organization. Two different modes of tags are supported: plain and secure mode. At
the moment only plain mode tags are supported in full functionality. Only serial
numbers are supported in secure mode.
Two different cards with 320 bytes or 1k bytes EEPROM memory are available. The
EEPROM memory is divided into pages.
Each tag is split into two parts: The administrative blocks (00h, 01h, 02h) and the
user area. Administrative pages are read only and cannot be changed. User data is
free for use. Additionally user data pages can be locked. This procedure is
irreversible.
The EEPROM of SRF55V10P is organized in 128 pages addressed 00h to 7Fh. The
EEPROM of SRF55V02P consists of 32 pages addressed 00h to 1Fh.

3.5 TAGIT®
TAGIT® labels are organized in a wide range of different page size and number of

As a default data is transmitted at 9600,n,8,1. Two protocol modes are supported.
The protocol mode is configured in the reader EEPROM. As factory default, the
ASCII protocol is used.
5.1 ASCII Protocol
This protocol was designed for easy handling. The commands can be issued using a
terminal program. Data is transmitted as ASCII hexadecimal that can be displayed on
any terminal program (e.g. HyperTerminal).

5.2 Binary Protocol
This protocol was designed for industrial applications with synchronization and frame
checking. Also an addressing byte for party lines (master slave, multi drop) is
included.
The protocol usually requires a device driver. Data is transmitted binary.
