Apple Card Support
We’re not sure when Apple’s innovative new credit card will debut (the only timeframe given was this summer). But iOS 12.3 has already been updated with a few code changes that will allow iPhones to support it. Specifically, hidden within iOS 12.3 betas is the actual activation process for the Apple Card.
As spotted by 9to5Mac’s Guilherme Rambo, the physical Apple Card will apparently come in a colorful envelope that sports a small glyph. To actually activate the physical Apple Card, users will touch their iPhones to this glyph — which actually contains an NFC tag. iOS 12.3 will then walk the user through the rest of the setup process.
