Capital One, Card
This is part of the FTF (Flip the Funnel) lane that strives to implement features to minimize calls to our call center, thus reducing overall costs.
The Lost/Stolen Card flow allows a credit card customer to use the app to lock their card and then report if it has been lost or stolen. If stolen, we then walk them through their transactions to determine if any fraudulent purchases have been made.
We have a similar feature on the bank side for debit cards. I worked closely with the designer to ensure a consistent experience across lines of business.
