11. Successfully Drawing Finger Over Scanner
The way a finger is drawn over the scanner is critical to having the scanner recognise
the print as easily as possible. With some practice the user can keep the FRR (false
rejection rate) lower than that which the statistics reflect.
Include as much of the surface of the finger (outermost finger limb) as possible.
Set the finger onto the uppermost limit of the guide, not coming in contact with the
sensor. Then let the finger fall onto the surface of the sensor and immediately draw
the finger down at a steady rate and with light pressure on the sensor. Perform this
freely but not rapidly. If the finger jerks over the sensor, it is a sign that too much
pressure is being applied. The finger must be pulled far enough over the sensor until
it no longer touches the thermal line sensor. Only then the scan is complete.
