ApplePay is only on iPhone 6. This means that the availability rate for this technology will get into (tens of) millions in a couple of years, based on the update cycle with the phone carriers. Realistically we're talking 2-4 yrs. Plenty of time for providers to get acquainted with the technology and to integrate it into their retail systems. For developers it would be interesting to see how the API looks like and if it will be available at all in any shape or form (which I doubt actually).

Well it's already available through Stripe: https://news.ycombinator.com/item?id=8292026 - so I'm pretty sure there's good news ahead :)

"the availability rate for this technology will get into (hundreds of) millions in a couple of years"

There - fixed that for you... Apple sells "(tens of) millions" of iPhones per quarter - and that tends to grow. A couple of years of sales add up to a lot of phones.

Apply Pay uses the same tech as existing contactless payments, like PayWave or PayPass, so the availability is already pretty high.

Also on the watch.

iPhone 5 and 5s will be pair-able with Apple Watch, so I would assume they will have access to Apple Pay too

According to the Apple Pay site, that'll be the case for in-store purchases.
