Your contactless cards broadcast your financial data wirelessly, all day, whether you're using them or not. Any criminal with a cheap reader can silently collect your card details in a crowded parking lot, airport, or checkout line — without touching you or your wallet. You'd never know it happened.
Covering your PIN doesn't stop this. Paying inside doesn't stop this. Your bank's fraud alerts don't stop this — they fire after your money is already gone. The only protection that works is making your cards impossible to read in the first place.
The Corven card sits in your wallet and creates a complete signal block around every contactless card near it. No broadcasting. No skimming. No exposure. Slide it in once and it works every single day without you thinking about it again.
