A new Apple patent has been published by the USPTO which reveals the transfer of Touch ID information via iCloud, as reported by AppleInsider. The patent shows a system where Touch ID information can be collected on a primary device and then transferred to a secondary device via iCloud for authentication. This new system has a profound usage in Apple Pay as well. This system can allow Apple Pay terminals, integrated with their own Touch ID sensors, to perform biometric authentication and process transactions without the need for presence of the primary device. In the earlier Touch ID system, the biometric information was stored only on the device. But the new system, according to the patent, will offer new options to maintain security.
