In this tutorial I will be implementing simple android app which will do one basic functionality and that is biometric fingerprint verification or authentication. One thing I want to share with you guys and that is some limitation of fingerprint in android studio. First fingerprint authentication is supported above the api 23 that is Marshmallow. Android will not allow you to access the fingerprint data or you can not store fingerprint data into any database. Android keep fingerprint data securely in internal storage. If you are thinking to get fingerprint data and save it in some database so it is not possible, android will not allow you to do that. Now question is how to use android api for fingerprint verification or authentication. There are few conditions in order to achieve fingerprint verification or authentication successfully which are
1. Your device must have fingerprint sensor
2. You must register at least one finger print in your device
3. You can used fingerprint android api only for api 23 and above api level, you can not used for api lower than 23.
4. It uses fingerprint from android internal storage, you can not update and store new fingerprint through app ( not android system ).
Advantages of Fingerprint verification or authentication
1. It is quick and easy to use.
2. It is highly secured because no body can access it only authenticated person can verify itself by only his fingerprint.
3. It is highly accurate because every person has its own unique pattern in finger and it can not be changed.
4. Required small storage , quickest and secured technique for transaction.
5. It enhance user experience.
Disadvantages of Fingerprint verification or authentication
1. Fingerprint authentication require additional hardware for fingerprint support
2. Cannot updated and reset once fingerprint registered
