Here is a credit-card-wireless icon for use at POS machines. Here in the states, this icon is used to demonstrate that a POS accepts wireless payment options...like Apple and Android Pay, and wireless credit/debit cards.
I'd suggest using the standard "contactless payment" icon for this or, at least, adding it as well.
I would disagree for their original logo, but if we modified it to just the wireless signal that could work.

That's the one I was referring to 馃槂
I'm for adding both, the credit card + two waves in material style (as icon for contactless cards in general), and the four waves with rounded corners, which is on all my three wireless/V-Pay cards (as brand logo of sorts).
Yea, this seems fine to add. Wish the contact payment standard logo wasn't so detailed, but credit-card-wireless gets the idea across.
Added the two.
