Now I feel better. A colleague reminded me that we do not have to rely upon the brands. Cards will have disappeared long before Mastercard's unrealistic timeline for removing the mag-stripe.
I am close to cardless already. I carry one card; however, I rarely have to use it; I usually pay with my watch. I use my card at my dentist and, of course, in restaurants. (In Europe they do not even need cards in restaurants. On a recent ferry trip, I asked if I could use Apple Pay. The bartender simply put his wireless point of sale device on the bar, just like in European restaurants.)
Because of the way I carry the one card, on two recent excursions into NYC, I simply forgot it. When the waiter presented the check, instead of putting down my card, I simply put down my iPhone with an image of my card. The waiter took it away without comment and returned it without comment. I signed the credit card receipt and we were done.
Most of my retail transactions are done with my watch. For e-commerce, I prefer merchants who offer PayPal, Apple Pay, or Google Pay. Many already do. More will do so as they learn that it protects them from fraud, perhaps at a higher, but efficient, transaction rate.
As I think about, it is almost too late to worry about the mag-stripe. The brands can do more to resist fraud by promoting check-out proxies, than by eliminating the mag-stripe.
