Harry McCracken is exclusively using Apple Pay this week:
When I resolved to leave my wallet at home and spend a week buying only those things I could pay for using my iPhone 6 and Apple's new Apple Pay service, I was prepared for the worst. I thought it might not work reliably--or at least turn out to be enough of a hassle to make me pine for my plastic.
Instead, the first couple of days have gone shockingly well, except for some issues getting cards verified for use with the service. I'm pretty confident I'm going to use Apple Pay quite a bit, even once this experiment ends.
In the article, Harry shares his experiences so far, the good and the bad. Also, it's been fun to follow him on Twitter this week.
