10 FinTech Innovations Disrupting Traditional Banking in 2025

8. Banking-as-a-Service (BaaS) Lets Any Firm Launch 'Bank' Services

Ever see a “Walmart MoneyCard” or a retail store offering its own checking account? That’s Banking-as-a-Service (BaaS) at work. Fintech providers like Green Dot help regular companies—whether retailers, startups, or even airlines—launch “their own” bank accounts and loans without building the tech from scratch. This means more choices for consumers, like getting paid directly into a brand’s app or earning cash-back for shopping at certain stores. But here’s a headache: if there’s a problem with your money, it might take a few calls to figure out who actually holds your funds. It’s also tricky for regulators, who now have to keep watch over a growing web of partnerships. For customers, the basics don’t change: check the small print, and know who you’re really banking with—even if there’s no traditional branch in sight.
