Capture a fingerprint
Important: A subject’s finger must touch the bezel in order for a fingerprint image to be captured (see bezel area in
Figure 2).
1 To capture a fingerprint, have the subject place a finger on the sensor and make sure that the finger is also touching
the bezel.
2 The subject must hold the finger on the sensor and bezel until the reader vibrates and the landing lights turn off,
indicating that the print was captured.
Troubleshooting tips
• Fingerprint image is too light - An image that is too light can occur when a finger is very dry. To remedy this, have
the subject apply moisturizer. If moisturizer is not available, have the subject touch the forehead in case enough
natural oil is present on the skin.
• Fingerprint image is too dark - An image that is too dark can occur when a finger is wet or excess oil is present. To
remedy this, have the subject wash hands with soap to remove excess oil and then dry thoroughly.
Power management
When a smartphone, tablet, or laptop is powered on or in sleep mode, a connected Nomad can draw a small amount of
power from it. When the Nomad is not in use, you should always disconnect it from the smartphone, tablet, or laptop to
preserve battery life.
Safety and handling
To prevent the sensor from scratches or other damage, always keep the Nomad in a protective case or covering when
not in use. The sensor can be cleaned gently with a mircofiber cloth.
If you need to remove the Nomad from the case, disconnect the cable and then push up
from the bottom of the case when possible. Grip the device only from the sides to finish
removing it. Do not touch or squeeze the sensor when removing the Nomad from or
returning it to a case.
