All of my cards were contactless in 2015, I'd been doing contactless payments for 5+ years (in the few places it was possible). But then the greedy, inept, and cheap American card issuers ripped out RFID in favor of only contact EMV chip, instead of going with dual chipped cards like pretty much the rest of Europe. And as merchants had to pay their own way to comply with the new chip requirements, they too mostly went the cheap route, which was to buy POS systems that support chip, not chip and RFID. The reason we have contact only cards, is issuers. The reason we have chip and sign, is issuers. They want the American consumer to have as many cards as possible, and different PINs for each card discourages having a wallet of 10 cards.
