I can't speak to regional banks or credit unions, in the US, but the major US national banks ALL have options to be able to be SMS'd, email'd or in-app instantly notified for a wide variety of events on or related to a card (auths, clears, bills due, bills paid, over a balance threshold, overdrawn, etc.) and the ability to freeze the card through the app or web until it is unfrozen. Capital One even has the ability to generate a one-time PAN to be used in Internet purchases.
