Operation and Cleaning 3-38Biometrics Fingerprint ReaderHigh quality fingerprint templates are imperative for the security of the biometricsecurity system. Low quality fingerprint templates can impact future read rates.Therefore, using the Biometrics Module should be done very carefully. In case ofinexperienced users who are using the module for the first time, the process should beassisted (guided) by an administrator or experienced user.Using the Biometrics ReaderPlace your thumb/finger flat and straight on the sensor. If this is not possible, try toplace your thumb/finger on the sensor in the same angle every time.Under normal usage conditions dirt, residue, oils, and other materials can collect onusers’ fingers. This can possibly cause poor collection of fingerprint data, which cancause performance degradation. For the best results it is recommended that the userkeep their fingers relatively clean and free of residues that may alter the sensorperformance.Scotch tape can be used to clean fingers. Adhere the tape to the finger and then pull itoff.
