I was standing in line at Subway in the Houston airport the other day, having just ordered lunch. I handed my Amex card to the woman at the register. She inserts it into the chip reader, and the moment she does, the Apple Wallet notification above for the charge appears.

It take another few seconds for the receipt to print, and for her to ask if I’d like my copy. “I’ve got it,” I respond. She looks somewhat confused, but shrugs and tosses the print copy as she hands me lunch.

I’m relating this story because it was just one of those small little moments where you realize that the world is changing in a small but significant way. Not signifiant in terms of “big picture” issues, but significant in terms of the “little things” that have been fixtures of our daily lives that are disappearing, replaced by something with a different character but the same essence.
