There are many Twitter accounts and Youtubers which often give accurate details leaking the upcoming Apple products. One anonymous account on Twitter that has a good track record shares more details about many Apple products that are in development.
One of the products that the Twitter Account mentions that are in works are the new iPad Air with under-the-screen Touch ID. This product has not been rumored until now.

According to the tweet:
“The new iPad Air will be using the mini led screen, comes with the full screen with no notch, not Face ID and Touch ID under the screen”
