I was at a Chevron gas station picking up some beer and tried using Apple Pay on my Apple Watch 3 LTE as I didn't bring my phone with me for Samsung Pay, which I usually use at that store. (I usually carry Samsung phone and leave my iPhone at home. However, I didn't bring any phone with me when I left the house for some errands.) I double clicked on the power button and put it against the NFC sensor and almost instantaneously the watch vibrated to signal the completion of payment process. The casher handed me the receipt to sign, I signed it and I was out the store with my beer. Of all places, the Chevron station closest to my home has NFC card reader. How convenient. I love it.
