What it does:

It scans your fingerprint and compares with your bvn fingerprint before confirming payment to prevent fraud.

How we built it:

Using FingerprintManger and KeyguardManager provided by the android system, we were able to use the device's fingerprint system to authenticate in our app.

Our greatest challenge:

Obtaining the user fingerprint in SHA-256 encrypted format for comparison.

We learnt a few things while trying to achieve this, one being able to obtain data from API's and working with it, also learnt how to work it device fingerprint.
