Credit cards are vulnerable to brute force kind attacks

Virtual credit cards have been a thing for years. I remember bank of america or Citi providing them to me 15+ years ago. If I recall it was a java app or maybe even a standalone exe. Shocked they never took off more broadly.

Robinhood absolutely nails this. Best virtual credit card system I have ever used. So seamless. Can auth a card for one time use, 24 hours, or indefinite until you cancel. Such a great UI / UX

It didn’t take off because it was easier to eat the costs of fraud than to maintain the system. It didn’t catch on simply because it’s pro-consumer.

MBNA (which got bought out by Chase) had a Flash-based virtual card app back in the early 2000's. I really enjoyed using it. I also can't understand why they haven't taken off, especially in the world of Everything Is A Subscription we're living in now. I adored being able to set expiration dates and spend limits to save ugly negotiations about ending subscriptions.
