What do your nose, the heel of your foot and
left nipple all have in common? Well,
according to this Reddit thread, they will all
work on an Apple Touch ID sensor. The same
can’t be said for right nipples, unfortunately.
Highly reputable Reddit source “
A_Gigantic_Potato ” published his
“comprehensive” list of different body parts
that will work with a Touch ID sensor. For a
part that was only meant to recognise
fingerprints, it turns out that the Touch ID
sensor is surprisingly versatile.
Here’s the complete list of body parts My
Friend has tested thus far:
Parts that do work:
• Fingers
• Palm of hand
• Big toe
• Index(?) toe
• Pinky toe
• “Palm” of foot
• Nose (very difficult)
• Back of index finger (very difficult)
• Heel of foot (works better than thumb imo)
• Left nipple (right refuses to cooperate)
Parts that do not work:
• Forearm
• Knee (That round bit of your ankle
• Belly
• Earlobes
• Eyelid
• Thigh
• Right and left Testicle
• Tip of Penis (underside)
• Tip of Penis (top side, although it’s
interesting to note that this generated the
best results although the results seemed to
deteriorate and got more errors as it got
flaccid)
A Friend conducted some spot testing with
my own iPhone, and I can vouch for the
validity of the results on big toe and that
round bit of your ankle. HR regulations
prevent me from conducting a complete test
at my desk.
Interestingly, the fingerprint sensor on a
Galaxy S7 doesn’t fare nearly as well. No
matter which angle I used, I couldn’t get it to
recognise my big toe.
is this a Bug or feature?
