Comparison of MacBook Air with M1 chip versus Windows laptop

Good afternoon,
My name is Vanessa and I have only just made my first account today. I have a quick question for everyone. I haven’t used a MacBook in about 10 years and have been using Windows mostly. However, I have noticed a few problems with my windows that have now necessitated me purchasing a MacBook Air With M1 chip since that’s easier within my price range.
I would be grateful if somebody could please explain to me where the touch ID sensor is on a MacBook Air? I have found information online but I don’t know how current it is. Does anyone have any Experience?
If you could let me know, feel free to comment below.
Thanks so much and can’t wait to hear from you.
PS for context, I am blind and have been so since birth. I’ve used VoiceOver on my iPhone and I’ve used it on an iPad before, but as I haven’t used the Mac in such a long time, this is why I’m asking this question.
