Capital One has become the latest financial institution to add fingerprint authentication support to their Android app. The US-based bank and credit institution has updated their Android app to give customers the ability to authenticate and access their accounts on their phones via their fingerprint. Setup of the new feature is easy and can be found off of the settings menu. Once it is enabled and configured, you can start the app then access your accounts by touching your fingerprint scanner on your phone. For security purposes, your PIN or Pattern authentication that you previously used will become the backup way to get into the app and your accounts.
