touch id is not working on ipad. I erased and tried to add again, but no luck.

Some users just have difficulty using TouchID. The causes for of TouchID being unreliable for some users - and not others - are many. Whilst not an exhaustive list, possibilities include:

• Very high humidity (“sweaty” fingers)
• Very low humidity (excessively dry skin)
• Poor fingerprint ridge-detail (excessive hand washing - or exposure to abrasive material, damaging fingerprint detail)
• Physical injury (cuts or splits to the fingertip)

If you have naturally dry skin, try using a “light” (non greasy) and easily absorbed skin moisturiser.
