  1. If twins can't have same fingerprints then why does Apple say that face ID is more secure… Apple you are making us fool huh?? Just kidding😛😂 I know the efforts and technology of face ID…

  2. Fingerprints are no that unique and there have been, in the past, criminal cases where they got the wrong person, who had very similar fingerprints to the perpetrator.

  3. I’m not lying when I say this, my mum was setting up her new iPhone and I was teaching her around. She set up her finger print. Then later on that day I turned on the phone with my finger on the scanner naturally. Then all of a sudden the iPhone unlocked. I showed my mum and it kept on unlocking. Then I tried my brothers finger and it didn’t work. My mum deleted the fingerprint but I said to keep it to show others. So weird..

  4. Many people (including myself) do not have readable fingerprints. At my work, I was one of three employees who had to sign in using number pads because our fingerprints did not register.
