PayPal has today announced the availability of their fingerprint-based authentication system in 25 countries. The system was first announced at MWC 2014 and is now ready for action on the Samsung Galaxy S5. With the app, users can simply swipe a finger over the home button on the S5 to authorize payments and perform other operations. This means you no longer have to login to PayPal with a username and password when using the mobile web, through apps or even in retail stores.

The S5 is also the first phone to incorporate the FIDO authentication standard that was developed by Google, Microsoft, MasterCard, and Lenovo.

John Lunn PayPal Developer Network:

Customers can use their finger to pay with PayPal from their new Samsung Galaxy S5 because the FIDO Ready software on the device securely communicates between the fingerprint sensor on their device and PayPal's service in the cloud. The only information the device shares with PayPal is a unique encrypted key that allows PayPal to verify the identity of the customer without having to store any biometric information on PayPal's servers"

PayPal has also introduced an new app for the Samsung Gear 2, Gear 2 Neo and Gear Fit that allows users to check their PayPal balance, receive payment notifications, and make payments right from their smartwatch.
