How can i make external fingerprint scanner device based android application

Hello developers
How can I make an external fingerprint scanner device based attendance system android application?
That fingerprint can be export in excel sheet from the database…

why don’t you try to learn the basics first and get comfortable with the components.
Try it,
Experiment it,
its not going to cost you anything, except time,

If you didn’t get success then show your blocks here and someone will help you.

Checking fingerprint as a credential is not recommended! Not every device has a fingerprint sensor. And, I don’t know if it’s possible to store fingerprint at any manner.
