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 proof. Code sleuth pdfu has found Car Key strings that mention an iPhone in the same string as both Ultra Wideband and Touch ID, which they say '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 has Touch ID references that aren't tied to specific hardware. Legacy terminology can also linger for years, with references to discontinued products like iPod still appearing in recent iOS code. So while Touch ID is expected, this detail doesn't confirm it.
