Hardware Requirements

PalmSecure Sensors

You'll need at least one Fujitsu PalmSecure sensor for testing and production:

Supported Models

Model	Use Case	Interface	Dimensions
PalmSecure F-Pro	Fixed installations, high throughput	USB 3.0	150mm x 80mm x 60mm
PalmSecure F-Pro+	Portable setups, lower throughput	USB 2.0	120mm x 70mm x 50mm

We recommend the PalmSecure F-Pro+ for most applications due to its performance and reliability.

Permissions and Access

USB Permissions (Linux)

For Linux systems, you'll need udev rules for sensor access:

# Create udev rule file
sudo nano /etc/udev/rules.d/99-palmsecure.rules

Add the following rule:

# Fujitsu PalmSecure F-Pro
SUBSYSTEM=="usb", ATTR{idVendor}=="04c5", ATTR{idProduct}=="1472", MODE="0666", GROUP="plugdev"

# Fujitsu PalmSecure F-Lite
SUBSYSTEM=="usb", ATTR{idVendor}=="04c5", ATTR{idProduct}=="1473", MODE="0666", GROUP="plugdev"

Reload udev rules:

sudo udevadm control --reload-rules
sudo udevadm trigger

Add your user to the plugdev group:

sudo usermod -a -G plugdev $USER
