The Google Play version of PayPal's Android app has been updated with support for fingerprint recognition on a handful of Samsung gadgets.
This capability existed already in the version of Android's PayPal app distributed through Samsung's own app store, but not in the Google Play version.
Samsung opened its fingerprint scanner up to third-party apps early in 2014, putting the ball in Apple's court, where it has since been completely ignored. But hopefully that changes if more big-name apps like PayPal continue to take advantage.
