I've done development on these types of systems. I can't go into too much detail for obvious reasons, but your answer is yes. When the details of a transaction seem to be unusual or have an association with high risk or fraud, you'll get an email, sometimes a call, sometimes they'll immediately freeze your account.
It's a security measure to protect both the bank and the customer.
- hrrsn 9y agoI've noticed my two banks vary wildly in how they respond to this (I'm non-US). Once I was notified that they were replacing my card due to suspected fraud only after I called them to ask why my card was being declined everywhere. The other bank disabled my card when placing an order on Doordash while in LA and I got an SMS, a notification from Apple Pay and a phone call almost immediately.
