Does the iPhone 5s fingerprint scanner work?

I have an iPhone 5s and I'd like to use the fingerprint scanner but I'm not sure that I trust it to fully work… Has anyone else tried it?

Yeah… Sometimes it work but sometimes not its not that reliable application.
sorry if I didn't helped

From my experience, it work every time as long as you set it up right! But you can also have a number passcode as a back up Hope this helps

Well millions are using it, so that should answer your question.
