I left my wallet on my work desk and a youngling helped walk me through using my phone to pay for my drive-through coffee order. I felt so cool and high tech.

Of course, when we got to “turn on NFC” the youngling asked what NFC was. I think I told him it was like Bluetooth and let the phone talk to the card reader.

My older “forgot my wallet” technique was to make an online order for pick up and enter my organically memorized credit card information into the online form.
