Placing Your Finger Correctly
on the Fingerprint Reader
When you place your finger on the fingerprint reader sensor to identify yourself, please
remember two things:
1. It is important that you use the correct finger. For example, if you place your left
index finger on the sensor, you will not be granted access if the system expects
you to use your left middle finger. When logging on, a screen shows you which
finger you are expected to use – it is marked with a dot.
2. Your finger should be properly positioned on the sensor. Poor positioning and
too much or too little pressure could result in an erroneous reading – which may
prevent you from gaining access to the system.
Correct Finger Placement
Most of the information in a fingerprint is located in the middle of the finger pad. There-
fore, it is important that the middle of the finger pad is placed in the sensor centre at
enrolment and logon.
• Press your finger pad flat to the sensor.
• Let the top of your finger pad touch the top of the sensor on your fingerprint
reader.
• Use medium pressure and avoid rotating your finger.
