How do you want to pay? It’s a question you’ve answered on-screen or in-person thousands of times, but your choices have always been limited. Imagine the flexibility to pay however you want – credit, debit, multiple currencies, frequent flyer miles, loyalty points, or digital payments - all on the same card or digital wallet.
