Note: TouchID via an app /= ApplePay.
Good first step but ... Seems optimized to increase security and reduce physical CAPEX for banks at the expense of convenience and security for customers.
If it's "take photo of a QR-code" with an app, or wake app on phone via BT or NFC, and subsequent authentication via Touch ID in iPhone and PIN entry on the ATM, it's not really Apple Pay.
Although it is an improvement of sorts over inserting a card, typing a pin and defining transaction, it is lousy compared to the alternative. It may be slower than a card approach for many users and result in more exposure for customer as they go thru a number of fiddly steps.
This process could be vastly streamlined and made safer for the customer (less time at ATM by:
1) allowing customer to prepare transaction prior to facing terminal (like in car), and
2) upgrading the terminals to include NFC antennae that allow customers to present prepared transaction on device and to authenticate, grab cash and run.
