Q: Touch is not working..How can i rectify that

Not sure exactly what you are asking. This is in the Apple Remote Desktop forum, and I don't think that has a touch function. Could you please provide more detail of your problem, what you were doing when you encountered it, and what you have done to try and correct it.

See this support document for assistance in the setup and troubleshooting of Touch ID. Use Touch ID on iPhone and iPad - Apple Support

As you can see there, the final step is to contact Apple Support if you cannot fix it yourself.
