NFC is actually a touch faster because it doesn't even require handing anything to anybody. Hold your NFC device to the sensor and it'll be done as fast as it takes you to extend your arm to give them the card. I first experienced this level of convenience with Mobile Speedpass 15 years ago, and was hooked... pay for gas in 1 second, every time. Put the thing near the thing, it lights up, and you're done. Simple as lifting your arm.
Cash evangelists are the same people that refused to get a cell phone until they absolutely needed to, and now refuse to get a smart phone. They proudly use the oldest version of their computer OS available that's still patched, and freak out when devs sunset it. Embracing skepticism and moral panic about technology gives them a feeling of control, superiority, and sense of purpose. They'll throw assumptions and anecdotes at you about how evil technology is, but in 5 years when it's considered outdated, they'll be touting the amazing benefits of it when the rest of the population has moved on.
