Find Fraud Faster
Does your bank send you alerts when you spend more than $100 in one charge? Or online charges? International charges? Most banks (all 4 of the ones I use) will alert you when a charge occurs above a specific amount. But you have to configure it. For most credit cards, you can also enable these kinds of alerts.
Look in settings for alerts on your bank or credit card's website (or an app if you have one).
