The new tablets will feature Touch ID for the first time, a gold color option, and be powered by the Apple A8 chip. Both slates could get a bump to 2GB of RAM.The rumored 12.9 inch Apple iPad Pro could be unveiled at the event, although that would be a longshot considering that the large-screened slate isn't due to be released until 2015.
The new iPad models will also support Apple Pay. But because the tablets are not expected to include NFC connectivity, iPad users will be limited to using the feature for online transactions and app purchases. In other words, you will not be able to swipe an iPad by a POS machine to make a payment at a brick and mortar store.
