Apple has launched "Tap to Pay for iPhone," a new feature that turns your smartphone into a point of sale (POS) device for businesses and merchants. This feature will extend support to “Apple Pay, contactless credit and debit cards and other digital wallets,” meaning that, unless Apple places a direct barrier for it, customers using Coinbase Card, Crypto.com Visa Card or a similar payment card can spend their Cryptocurrency holdings to make payments via Tap to Pay.
