Yes my bad, it does have 1st gen TouchID, it must be the A13 speed resulting in faster authentication. Looks like Apple is doing as much as they can to keep costs down and maximise on profit margins. Old design which came out in 2014, first gen TouchID, non laminated display, lightning port, no dual stereo speakers, 1st gen apple pencil. Its basically 2014 ipad air but with A13, better ram, support for pencil and keyboard.
2013 not 2014
Air 2 is 6.1mm OG Air is 7.5mm like the iPad 9 has
