Yeah. Because they can run out of power, they are easily damaged, and, generally, bug and exploit ridden.

A bank card is near indestructible.

Do you know the size of fraud departments at banks and payment providers, and the budgets going into fraud prevention every year? A bank card is as easily destructible as a smartphone is, but is far less secure, as we're sacrificing security for usability.

If we're comparing smartphone vs bank cards, it's only fair to presume that the bank cards are equipped with EMV, because magstripe terminals won't be able to accept smartphone either. In that case, I fail to see any security advantage over smartphones.

Magstripe terminals can accept smartphone generated pins with a software update, you just enter the (OTP) pin manually.

I've seen this used at Wells Fargo ATMs.

Modern cards disable the magnetic stripe, and the chip is surprisingly secure.
