RFID Systems

Introduction

Brady RF/ID systems consist of Brady RF/ID tags and a reader/writer for reading data from tags
or writing data to tags. Several different types tags and various reader options are available to
suite any application.

Brady RF/ID Tags

Brady RF/ID tags consist of a microchip, coil antenna, and packaging. Packaging and microchip
options can be combined to fit any RF/ID tag requirement.

Microchip options include read only, read write and several different memory capacities for
read/write applications. Typically, read only tags are randomly preprogrammed with 40 bits(10
HEX Characters) of permanent data. Versions of read only tags are available which can be
programmed once with a designated number. This number is then permanently stored in the tag
and can be read many times. This type of tag is typically referred to as a WORM (write once read
many).

Read/write tags have permanent data as well as programmable data. The permanent data is
similar to a read only tag. It is usually 32 bits (8 HEX Characters) of data which can not be
changed. Read/write tags also have memory which can be changed. The amount of changeable
memory in a read/write tag ranges from 152 bits (19 Alphanumeric Characters) to 1536 bits (192
Alphanumeric Characters). Versions of read/write tags are also available with password
protection or data encryption for high security applications that require secure data transmission
between the reader and the tag.

Packaging options include a variety of forms as well as different case materials for a wide range
of operating temperatures and chemical resistance.

Brady Wand

The Brady Wand is an RF/ID reader which interfaces to a host PC or hand held data collection
device through standard RS-232/422/485 or Wand emulation hardware format. The reader is
typically powered from the host device with 5V D/C. If an un-powered data port is used, an
external battery source must be provided to power the reader.

The Brady Wand was designed to be used in various Industrial applications which require rugged
and reliable equipment. Versions of the Wand are available with an Intrinsically Safe Rating
which allow them to be used in explosion hazard areas. The Wand is water resistant and can
withstand many of the harsh chemicals found in industrial manufacturing and petrochemical
processing. In environments where visual and audible indicators can not be heard or seen, the
Brady Wand has a unique vibrating feature for indicating reader status to the operator.

Use

Operating the Brady Wand is very easy. To read/write to a tag the operator presses the large
activation button located above the hand grip.(see fig.1). Once the button is pressed, the reader
electronics sends out a radio frequency field to search for a tag. During this time the red LED,
located above the button, will illuminate indicating that the Wand is in search mode. When a tag
is present within the field of the reader antenna, the microchip inside the tag is activated and
transmits its ID code back to the reader. . If the data received from a tag is valid, the green LED
located above the activation button will illuminate, an audible “beep” will sound, and the wand
will vibrate for a short period of time.

After the reader receives the transmission from the tag, it converts this information RS­232/422/485 or Wand emulation format and transmits the data to the host.

The Brady Wand can also be used remotely without pressing the button. When used for remote
read/write operation, commands which activate the reader/writer are sent from the host to the
Wand without the need for pressing a button. (See Programmers Guide for information on host

commands).
