Description
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. Sound impossible? Episode Six makes the seemingly impossible happen every day.    We’re a global provider of API-based payment processing and wallet management infrastructure.
