It means that when the phone officially launches in April, owners with a PayPal account will be able to swipe a finger on the devices homekey to buy anything from an online store — if it accepts PayPal that is. By working with Samsung to leverage fingerprint authentication technology on their new Samsung Galaxy S5, we are able to demonstrate to consumers [that they] dont need to sacrifice convenience to increase security, says Hill Ferguson, PayPals chief product officer. With a simple swipe of a finger, consumers can still securely log into their PayPal account to shop and pay with the convenience that mobile devices afford.
