Wirex

Wirex powers cards and banking infrastructure worldwide, and here on HackerNoon we share the practical “how it works” behind modern finance — cards, banking infrastructure, compliance, and making digital money usable in the real world. We publish educational, behind-the-scenes explainers for both everyday users and product builders: from what it takes to launch a card program, to how Banking-as-a-Service APIs and payment rails connect the dots between wallets, cards, and merchants. Trusted by 7M+ users since 2014, Wirex has processed $20B+ in transactions across 130 countries. As a principal Visa and Mastercard member, we also explore how crypto becomes spendable anywhere—instantly and effortlessly.
