Ask HN: How did Favor get my new credit card #
So I recently got a new credit card (lost card replacement). I activated it this evening and updated my pay pal and über apps on my phone with it. When I logged into favor, they already had my new card #?!?!?!
- FaisalAbid 11y agoStripe has a feature that does this
- jeffmould 11y agoNot sure the exact mechanics behind it, but essentially the banks send out updates to credit cards to processors. Processors like Stripe then automatically update those details within their systems. https://support.stripe.com/questions/how-can-i-keep-customer-card-details-up-to-date https://support.stripe.com/questions/how-can-i-keep-customer...
