At the very beginning, let's explain what Touch ID is and how it works.
What is Touch ID?

First introduced in 2013. Touch ID is based on the capacitive touch sensor that can read and analyze the subcuticular layer of skin to identify each person's unique fingerprint to make it easier to perform tasks such as downloading applications and unlocking iOS devices. Touch ID is available in your applications Apple and third-party applications, allowing users to protect sensitive data such as passwords or notes, using fingerprint.

The fingerprint data used for Touch ID is stored directly on each iOS device in a "Secure Enclave" and is never available in the cloud.

Touch ID versions

So far, there are two generations of Touch ID technology, the first was introduced in 2013, the second was introduced with the iPhone 6s and 6s Plus in 2015, and boasts speeds up to twice as fast as its predecessor. As for the second-generation Touch ID, it is noticeably faster and more reliable, and it is worth investing in. Fortunately, it's used in all the latest iPhones that come with fingerprint scanners - in fact, you'll have a hard time finding one that still uses first-generation Touch ID. Surprisingly, Apple still makes some first-generation Touch ID iPads, so keep in mind that this will be slower than the second-generation model.
