Some Disadvantages of iPhone's Touch ID

Touch ID is one of the major changes in the iPhone. It recognizes your fingerprint and you can make it as your password. But, this has some disadvantages.

1. Some people see it as being intrusive as it encroaches on anonymity.
2. Like the fragile screen of a phone, the lens of the scanner may also be affected by overuse/impact.
3. The condition of a persons skin may affect the scanner, such as the dryness or oils/dirt.
4. Fingerprints may be affected by injuries, illness or age.
5. When your home button gets scratches, it won't recognize your fingerprints anymore. And here is a video below that shows it.
