Again, the only way I would have known about these charges before my monthly statement arrived is the notification emails from Capital One. This is the second time they've saved me from losses, the first being when my credit card was compromised during a data breach in 2014.
Capital One isn't the only financial institution that offers transaction alerts, most credit card companies and banks do, but they're only useful if you're taking advantage of them. So the lesson today is, if you haven't already enabled transaction alerts for your credit cards and banking, do so.
Such alerts are one of the easiest methods for detecting a compromised credit card in the early stages.
