2. Functional description of the OBID
®
i-
scan
-system
The identification system
OBID
®
i-
scan
is an inductive transmission system for touchless identifi-
cation (ID) of moving objects. The components of the write/read system facilitate the writing and
reading of passive data carriers (Transponder) with an actual frequency of 13.56 MHz, the so-
called „smart labels“. It consists of a reader ID ISC.LR200, one or several antennas and one or
more smart labels used as a data storage medium.
These smart labels are generally paper badges or tags with a wafer-thin transponder integrated for
communicating with RFID read/write devices.
If a smart label gets into the antenna’s local magnetic field, it is powered and may be read and
written. Data is received by the same reader antenna that also produces the magnetic field and
sends the data to the data carrier.
The magnetic field and all data sent and received by the data carrier are able to penetrate almost
all non-conductive materials, so that even hidden writing and reading is possible.
The reader’s anticollision function facilitates the simultaneous reading of up to 50 smart labels per
second.
3. Features of performance of antenna ID ISC.ANT300/300
The Antenna ID ISC.ANT300/300 is a single-loop antenna with pre-set adjustment electronics and
has been optimized as a transmitting- and reception antenna for reader ID ISC.LR200. . At a cali-
brated transmitting power of 4 W a reading range of up to 55 cm is possible. Furthermore, it can be
used with other readers having a transmitter frequency of 13.56 MHz and an output impedance of
50
Ω
.
The antenna has been factory calibrated on a wood block for an impedance of 50
Ω
. After having
been installed in other surroundings, the antenna may be re-tuned for a defined range with the help
of jumpers.
The antenna is suitable for both object- and personal identification. The preferred direction of a
smart label is parallel to the antenna’s surface. The right position to obtain a maximum range
would be above the centre of the antenna’s surface.
