If image capture process takes more time then the image will be bright on the image sensor. An algorithm is used for this test. It tells you that the captured image is too light or deep. After which the sound of a beep comes, which alerts you and then again brings you back to the process.

This device alerts you even when the captured image does not have an alternative light and sufficient light. After these tests, the scanner tells you whether the image is correct or using the other LED indicator through the beeping. Now the captured image is saved in flash memory. Which is then transmitted to a computer for the next step. Now it will be the computer's work that the image has to be stored in the database or in the database it is already compaired with the Save fingerprint.
