Apple's iPhone Ultra is widely expected to feature Touch ID instead of Face ID, but references found in the iOS 27 beta probably shouldn't be treated as definitive proof. Code explorer pdfu found Car Key strings linking an iPhone with both Ultra Wideband and Touch ID, claiming this "confirms" Touch ID for the foldable since "all existing iPhone models with an UWB chip, starting with iPhone 11, use Face ID." However, Apple's codebase often contains Touch ID references that aren't tied to specific hardware. Legacy terminology can linger for years, with references to discontinued products like iPod still appearing in recent iOS code.

While Touch ID is expected, this detail does not confirm implementation.
