1Introduction
The Prox-Booster and Smartcard-Boosters are dual-ID tags enabling simultaneous identification of the inserted
personal ID card and the embedded vehicle ID resulting in rapid driver and vehicle monitoring.
The Booster allows an inserted Proximity or Smartcard driver ID card and embedded vehicle ID to be read from a
distance up to 10 meters (33 feet) in combination with NEDAP TRANSIT readers. This solution substantially enhances
the level of security when controlling activities of vehicles that are regularly used by different drivers.
Additionally, a fully integrated vehicle and personnel access solution can be implemented.
The Smartcard-Booster Ultimate additionally supports encrypted authentication using diversified AES128 bit keys, in
combination with the TRANSIT Ultimate and the Security Key Pack.
For more details about the NEDAP TRANSIT Ultimate reader refer to the corresponding installation guide.
The combined vehicle and driver ID is a unique NEDAP patented feature.
Optionally the Booster can also be operated in single-ID mode, in applications where only the personal ID card is used.
The following personal ID card types are supported with the Boosters:
•Prox-Booster 2G
NEDAP
HID-PROX
EM4100 and compatible
•Smartcard-Booster 2G
•
Smartcard-Booster Ultimate
MIFARE Classic
MIFARE Ultralight
MIFARE DESfire EV1/EV2/EV3
HID iCLASS UID
ISO14443A CSN
ISO15693 UID
Calypso PUPI and free files
Warning: Do not leave card in the Booster when leaving the vehicle, as this presents a security risk!
Warning: Do not leave card in the Booster for long periods of time in extreme heat, as this may damage the card!

2.1 Dimensions
The Booster is easily mounted to the inside of the car’s windshield by means of suction cups. Users should ensure the
visual contact between the Booster and TRANSIT reader is unobstructed with items such as stickers or metallized
windshields (see also chapter 2.3 about solar control windshields).
Note that the Booster's suction cups must be faced toward the reader to achieve maximum reading distance.

2.2 Temperature considerations
The Booster is designed to operate within the extreme temperature ranges, which often occur behind a vehicle’s
windshield during the winter or summer seasons (-20°C to 85°C / -4°F to +185°F). However, the personal ID card
inserted in the Booster may not be designed to withstand such temperatures and could suffer damage as a result.
Nedap recommends to remove the personal identification card when not in use.
2.3 Solar control windscreens
From 1997 onwards, several car manufacturers introduced vehicles with solar control windshields. The solar control
windshields are equipped with a metalized coating, which can block the TRANSIT signal from the Booster mounted on
the inside of the windshield of the vehicle.
Most of these windshields have a metal free zone where transponders can be mounted. The metal free zone of
metalized windshields is most often found in the middle of the windshield behind and slightly below the rear-view
mirror. In vehicles manufactured after 1998 the metal free zone should be indicated on the window.
We advise the owner to contact the local car dealer if it is not clear where the aperture is exactly positioned in a certain
vehicle and where the transponder should be mounted.

3Identifying the Booster with a TRANSIT
3.1 How to use the Booster
Place the Booster on the inside of the windscreen of your vehicle as described in chapter 2. The driver inserts his
personal ID card and activates the Booster’s button.
A beep should indicate that the card was successfully read. A low beep indicates that card reading failed. See chapter 6
for details about the buzzer indications.
The TRANSIT reader can identify your card up to a distance of 10 meters (=33 ft).
After 5 seconds the Booster returns into sleep mode. The booster will remain active when in 'always-on'-mode.
The driver should remove his personal ID card from the Booster when leaving the vehicle.
3.2 Reader output
The Booster is a battery operated passive tag. The information from the tag is sent to the reader by a method called
modulated backscatter. This means that the 2.45GHz signal coming from the reader's antenna is modified in such way
that it can be recognized by the reader.
The examples below assume that a TRANSIT reader with P81 firmware is used and show the messages transmitted on
the RS232 interface to a host system (TXD). Refer to the TRANSIT firmware manuals for more details about the reader
communication protocol.
3.2.1 Dual ID mode (Vehicle ID + Driver ID)
The Booster is inactive until the driver inserts his personal ID card and pushes the Booster’s button. Once the button is
pushed the Booster reads the personal ID card and beeps upon a successful read. Both vehicle-id and driver-id are
transmitted to the reader for 5 seconds. Afterwards the Booster automatically deactivates again. The booster will
remain active when in 'always-on'-mode.
Example
vehicle-id = 123, driver-id = E4947C46:
If 'Extended-length (default)' is configured, the following message is transmitted to the host:
TXD = Y000000012300000000000000E4947C46P
C
PRRRP
L
PRFR
If 'Standard-length' is configured, the following message is transmitted to the host:
TXD = U000000012300E4947C46P
C
PRRRP
L
PRF
Event identifier ('Y' or 'U').
Vehicle-id (10 digits).
Driver-id (10 or 22 digits).

3.2.2 Single ID mode (only Driver ID)
The Booster is inactive until the driver inserts his personal ID card and pushes the Booster’s button. Once the button is
pushed the Booster reads the personal ID card and beeps upon a successful read. The data is transmitted to the reader
for 5 seconds. After that the Booster automatically deactivates again. Always-on-mode is not supported in single-ID
mode.
Example
driver-id = 871111111117100944:
If 'Extended-length (default)' is configured, the following message is transmitted to the host:
TXD = Z00000000000000871111111117100944P
C

4Smartcard configuration
The Smartcard-Booster can be configured by means of a configuration card. This configuration card is programmed
with the configuration settings.
Configuration is only required if the factory default settings are not sufficient. The default settings are described in
chapter 4.7.
4.1 Configuration procedure
Every Booster used in the application should be configured with the configuration card. The easy configuration
procedure is described below.
Insert the configuration card in the Booster and push the button. The Booster sounds the buzzer with an increasing
frequency (♪♪♪) to indicate that the configuration card is accepted.
4.2 Config card types
The configuration card must be a Mifare card of below type.
•Mifare Classic 1K / 4K * Accepted by all Smartcard-Boosters
•Mifare Desfire EV1 ** Not accepted by older Smartcard-Boosters
* Notes about Mifare Classic config cards
The Mifare Classic config cards are accepted by all Smartcard-Boosters including the very first models from year 2007.
Warning: the security of the Mifare Classic cards has been compromised. Therefore allow only trusted parties to
perform the configuration and keep the configuration cards in secure location.
** Notes about Mifare Desfire EV1 config cards
Mifare Desfire EV1 config cards ensure a high level of security.
Desfire config cards are only accepted by Smartcard-Booster 2G and Smartcard-Booster Ultimate since year 2019.
How to identify if Smartcard-Booster supports Desfire EV1 config cards?
Yes, if the Booster is marked with revision B next to product number. E.g. '9948554 B' or '9982809 B'.
Yes, if the Booster plays Dutch national anthem when button is pressed while inserting the batteries.

4.3 How to create a configuration card
The configuration cards are created using the NEDAP Smartcard-Booster configuration software. This software can be
downloaded from our partner portal; https://portal.nedapidentification.com.
Figure 2: Smartcard-Booster configuration software
4.3.1 Target device
The Smartcard-Booster Configuration software is typically used to configure the Smartcard-Booster. However it also
supports some older (no longer available) booster models. The user-interface is adapted to the selected target device.
Select in the ‘Target’ menu which booster model you are about to configure.
•Smartcard-Booster
•Transition Booster (old) not covered in this manual
•Prox Booster EM4x50 / Titan (old) not covered in this manual
4.3.2 Creation procedure
Follow the procedure below to create a configuration card with application specific settings.
1. Specify BOOSTER OPTIONS see chapter 4.3.3.
2. Specify CARD READ SETTINGS see chapter 4.3.4.
3. Write the configuration into a config card see chapter 4.4.

4.3.3 Booster options
4.3.3.1 Operating mode
Select Booster operating mode. See available options below.
Booster (only Driver-ID)
Single ID operation. Up to 16 bytes of data from the personal ID card is read. The Vehicle-ID is omitted.
Combi-Booster (Vehicle-ID + Driver-ID)
Dual ID operation. Vehicle-ID combined with up to 11 bytes from the personal ID card.
Tacho-Booster (Vehicle-ID + Driver-ID + Tacho-Counter)
Vehicle-ID and Driver-ID combined with Tacho-Counter value. If this option is selected than automatically extended-
length is selected. See chapter 5 for more information about tacho booster function.
4.3.3.2 Active mode
Two activation modes are possible: Switched or Always-on.
The setting can only be changed when the Booster originally was in switched mode!
Switched mode is selected when the operating mode is Booster (only Driver-ID).
Switched mode (active for ± 5 seconds)
In switched mode the booster is active for approx. 5 seconds after the reading the inserted card (button is pushed).
Always-on (continuously active)
In always-on mode the booster remains active. When the booster's button is pushed the booster will read the inserted
card. If a card was identified, the booster will check every few minutes if the inserted card is still present.
4.3.3.3 Frame length
Extended length (default)
Select extended-length in order to support all transponder types and maximum amount of data. The identification
speed is a bit slower compared to applying standard-length.
Standard length (backwards compatible, faster identification)
Select standard-length in applications where compatibility with older types of transponders or where fast identification
is important.

5Tacho booster
The tacho booster function requires the Booster to be wired to the speed pulse generator of your vehicle. The Booster
will count the number of pulses generated, which indicate the vehicle’s mileage.
Tacho input specifications
•Input voltage: 6V to 24V (max. 30V).
•Polarity reversal tolerant.
•Input prescaler 1:256.
•Maximum pulse frequency 850Hz.
•Maximum vehicle speed 255km/h (at 12 pulses/meter)

The exact wiring details and connection location very much depend upon the brand, type and model of your vehicle.
Contact your vehicle dealer for more information about the speed pulse generator in your vehicle.
Reader output
The driver inserts his personal ID card and pushes the Booster’s button. Once the button is pushed the Booster reads
the personal ID card and beeps upon a successful read. Both vehicle-id, driver-id and tacho-counter are transmitted to
the reader for 5 seconds. Afterwards the Booster automatically deactivates again (unless in 'always-on' mode). The
Booster will keep updating the tacho counter also while inactivate.
Example: reader output: vehicle-id = 123, driver-id = E4947C46, tacho-counter = 100000 pulses (=hex 186A0):
TXD = X000000012300E4947C4680000186A0P
