Well, do bear in mind that the iPhone is pretty popular – so you've probably got a decent chance of wanting to transfer money to someone with a compatible device – maybe 25% or so? Knowing Apple's UX, it'll be rather easy-to-use if it's available – so I'm not sure that the overhead of 'figuring out if the other person uses an iPhone' would be any higher than figuring out if they use Venmo or PayPal or Square or whate…
> Knowing Apple's UX, it'll be rather easy-to-use How can we assume this? This exact thing has been tried many, many times - and sometimes to great success. What inherently makes you believe Apple's spin will be so much better than the other services and their unique problems? The challenge Apple will face has nothing to do with UX - it will have to do with userbase. It's likely (although not absolute) that using thi…
Obviously we can't know for sure – but it does seem like a pretty safe assumption. Apple Pay is a good experience at the moment; it's easy to see how that experience could be extended to inter-device transfers (bring them close together, enter the amount to transfer, Touch ID and done – or something similar).
The challenge Apple will face has nothing to do with UX - it will have to do with user base.
The service will likely be available instantly to literally tens of millions of people with no additional effort on their part, as soon as Apple roll out a software update. That's a big benefit for Apple.
It's likely (although not absolute) that using this service will require an iOS device. Given Android devices far outnumber iOS devices, this may pose a problem.
I think I responded to this elsewhere, but that's only true globally. Bear in mind that even Apple Pay is only available in the US and the UK at the moment; iOS share in those countries is around 40%.
Other services like PayPal and Square are universal services (device agnostic), and accounts are free (compared to Apple's barrier to entry which will likely cost you an iOS device).
They do have the additional barrier of not being available to all users by default, though.
