In this Deep Dive, we unpack the world of launching a card programme—from the evolution of payment cards into a trillion-dollar industry to the nuts and bolts of building, scaling, and monetizing your offering based on Marqeta’s experience. We break down the differences between prepaid, debit, and credit cards, explore the four-party model that powers payments globally, and outline key components like licensing (network vs. regulatory), payment processors, and compliance essentials. We also cover cost considerations, from card production to fraud monitoring, and revenue strategies like interchange, cross-selling, and network incentives. Thinking of scaling internationally? We highlight what to watch for, including regional nuances and choosing the right partners. Whether you’re starting out or looking to optimize, this guide gives you the framework to build and grow a successful card programme.Let me know what you think about this week’s newsletter, and connect with 10,000+ other fintech enthusiasts, on Slack at www.thisweekinfintech.com/community and in WhatsApp here (Americas & Europe) and here (Asia & Africa).Before we dive deeper into the card programme world, you’ll need some useful context to the card and payments landscape.
