Apple Inc. introduced a new iPad to its lineup, the iPad Air 2, its thinnest iPad ever. Sitting at 6.1mm thin, the iPad Air 2 is 18 percent thinner than the first iPad Air.

The new Apple tablet features a number of new features such as a faster A8X processor, 8 megapixel camera, laminated display with anti-reflective coating and Touch ID fingerprint reader. Apple needs this iPad to convince current iPad users to upgrade to help reverse sliding sales of the device.

The Touch ID feature on iPad Air 2 works with Appleā€™s online stores and online purchases through Apple Pay, but won't support the mobile payment service's in-store payment feature.

The iPad Air 2 with Wi-Fi starts at $499 for 16GB, $599 for 64GB and $699 for 128GB. Cellular versions retail at $130 more. Pre-orders start Oct. 17.
