Question: does the ipad air 1 have touch id

Answer: No, Although the Air inherits most of the same hardware components from the iPhone 5S, such as its 64-bit Apple A7 system-on-chip and Apple M7 motion processor, it uses the same home button that was built in previous iPad models and therefore does not support Touch ID and fingerprint sensor. The A7 present in the iPad Air is slightly different however, in that it does not use a PoP design which stacks the RAM on top of the SoC. It also features a metal heat spreader to compensate for the slightly faster clock speed and better thermal management. The Air also includes a 5 megapixel rear-facing camera (iSight), a FaceTime HD front-facing camera, support for 802.11n, and an estimated 10 hours of battery life. It boots faster than any previous iPad model.
