The iPad Mini 3 is the third-generation iPad Mini tablet computer designed, developed and marketed by Apple Inc. It was announced alongside the iPad Air 2 on October 16, 2014 and released on October 22. It uses primarily the same design and hardware as that of its predecessor, the iPad Mini 2. Its new features are the addition of the Touch ID sensor compatible with Apple Pay, differing storage sizes and being available in a gold color, as well as the previous colors.
iPad Mini 2 and 3 have a similar outer shell design.
Touch ID is an electronic fingerprint recognition feature designed and released by Apple Inc. that allows users to unlock devices, make purchases in the various Apple digital media stores, and authenticate Apple Pay online or in apps. It can also be used to lock and unlock password-protected notes on iPhone and iPad. Touch ID was first introduced in iPhones with the iPhone 5s in 2013. In 2015, Apple introduced a faster second-generation Touch ID in the iPhone 6s; a year later in 2016, it made its laptop debut in the MacBook Pro integrated on the right side of the Touch Bar. Touch ID has been used on all iPads since the iPad Air 2 was introduced in 2014. In MacBooks, each user account can have up to three fingerprints, and a total of five fingerprints across the system. Fingerprint information is stored locally in a secure enclave on the Apple A7 and later chips, not in the cloud, a design choice intended to secure fingerprint information from users or malicious attackers.
