The online payment unit of eBay Inc (NASDAQ:EBAY) PayPal is already working on integrating the iPhone 5S fingerprint reader into its mobile payment apps. A group of PayPal developers attended a session about Touch ID, Apple’s fingerprint-scanning system, at Apple’s annual Worldwide Developers Conference (WWDC) in San Francisco.
Touch ID will enable PayPal and other apps to authenticate users with a fingerprint scan instead of passwords. This week at WWDC, Apple said Touch ID integration will become available for third-party app developers through an API. As of right now, Touch ID can only be used to unlock the iPhone 5S or authorize iTunes purchases.
