From the Store description:
Bring your favourite Kodak Moments to life with our incredible printing app – whether you’re on the move, or sitting comfortably at home! The My Kodak Moments App lets you print your photos from your smartphone, wherever you happen to be.
No need to upload anything to your computer – just select the photos on your phone, place your order and then collect from your nearest store. Simple as that.
Already in store? The My KODAK MOMENTS App also features a fast and convenient way to do this in-store at Wi-Fi enabled KODAK Picture Kiosks. Your photos can be seamlessly and securely transferred to the kiosk wirelessly, so there’s no need for any cables or memory cards. Connect to the kiosk with your smartphone, choose your photos and print. It's fun, fast and convenient. Get started by downloading the free app.
How to use your Windows Device with a KODAK Picture Kiosk: When you connect your device to the kiosk, you’ll be asked to select your device type. If you don’t see the Windows Phone photo upload instructions on the kiosk (some KODAK Picture Kiosks are still being upgraded), select the one on the far right instead and follow the prompts. Be assured that you can use your Windows Phone at any kiosk today, and very soon, all will display Windows Phone photo upload instructions as an option.
I'll try it as and when I come across a kiosk, but they're not exactly numerous at the moment. Here's the map for the area I live in, comprising over half a million people:
So not too many options! Some screens of the My Kodak Moments application in action:
You can grab it here in the Store - it's a free download, of course, any payment is for prints in the fullness of time, etc. I've no idea what forms of payment are included. Has anyone used this service for real at a kiosk?
There's also a promo video, albeit using an Android smartphone instead(!):
