NEW YORK (AP) — If there ever comes a day I can ditch my wallet and use my phone to pay for everything, I’ll look back to my first purchase through Apple Pay: a Big Mac and medium fries for $5.44. That wallet-free day won’t be coming for a while, if ever, but Apple’s new payments system brings us much closer.

There were a few unexpected steps setting up Apple Pay on Monday, and the employee at a local McDonald’s looked befuddled as I stood there after waving an iPhone 6 over the wireless reader in front of the cash register. The transaction hadn’t gone through, so she was waiting for me to pay. I thought I had, but I had pressed the phone’s fingerprint ID sensor too hard, getting me out of the transaction instead of authorizing it.
