When will they just ping my phone to confirm the purchase? Are they stuck in the sixties?

I don't want my CC company pinging my phone, a PIN is much more convenient:

PIN: Insert card, 1234, enter.

Phone: Insert card, wait for notification, unlock phone, select notification, confirm purchase, wait for confirmation to get back.

Plus, if you're somewhere without cell reception or your phone battery is dead, what do you do?
