Have you ever been ready to swipe your card for a large purchase for it to bounce back? It’s annoying sometimes, but banks put this kind of thing in place to protect you. As institutions learn more about the behavior of scammers, fraud detection systems are becoming more advanced (and more sensitive). Bank security experts have noticed that routine behaviors could potentially trigger fraud alerts if they deviate from your usual patterns whatsoever. That said, here are seven money habits that could trigger these alerts and freeze your funds, or land you in the middle of a fraud investigation.
1. Making Large Transfers at Unusual Hours
Sending money at 2 a.m. isn’t illegal, but it’s definitely suspicious to your bank’s algorithm. Financial institutions track your typical transaction times, and sudden deviations can raise red flags. A large transfer outside of business hours may look like a hacked account or a scam in progress. Even if it’s legitimate, it could trigger a temporary hold. To avoid this, schedule big transfers during normal banking hours whenever possible.
2. Logging In From Multiple Devices or Locations
If you check your account from your phone in Monroe, NC, and then log in from a laptop in another state an hour later, your bank might think your credentials were stolen. This is especially true if you’re using public Wi-Fi or a VPN. Banks use geolocation and device fingerprinting to detect anomalies. Too many logins from different places in a short time can lock you out. Stick to one or two trusted devices and avoid logging in while traveling unless absolutely necessary.
3. Rapid-Fire Purchases in Different Cities
Let’s say you buy gas in North Carolina, then 30 minutes later, there’s a charge in Florida. That’s a classic fraud red flag. Banks monitor geographic consistency in your spending. If your card is used in two distant locations within a short time, it may be flagged as a cloned card. When traveling, notify your bank in advance to reduce the chance of a false alert.
4. Depositing Checks Then Withdrawing Cash Immediately
This habit is a major trigger for fraud alerts, especially if the check is from a new source. Banks are wary of check-kiting schemes, where funds are withdrawn before a check clears. Even if you trust the sender, your bank may not. Withdrawing large amounts right after a deposit can result in a hold or investigation. Wait until the check clears before accessing the funds to avoid unnecessary scrutiny.
5. Using Zelle or Venmo for Unusual Amounts
Peer-to-peer payment apps are convenient, but they’re also a hotbed for scams. If you suddenly start sending or receiving large sums through Zelle, Venmo, or Cash App, your bank may flag the activity. This is especially true if the recipient is new or the transaction memo is vague. Fraudsters often use these platforms to move stolen funds quickly. Keep your transfers consistent and always include clear notes.
6. Ignoring Two-Factor Authentication Prompts
Skipping or disabling two-factor authentication (2FA) might seem like a time-saver, but it can make your account look vulnerable. Banks see this as a potential sign of compromised credentials. If your account is accessed without 2FA from a new device, it may be frozen automatically. Always enable 2FA and respond promptly to verification requests. It’s one of the simplest ways to avoid triggering fraud alerts.
7. Making Multiple Failed Login Attempts
We’ve all forgotten a password or mistyped it once or twice. But repeated failed login attempts, especially from different IP addresses, can look like a brute-force attack. Banks may lock your account or require identity verification to restore access. If you’re having trouble logging in, use the “forgot password” option instead of guessing. It’s safer and less likely to raise suspicion.
Stay One Step Ahead of the Algorithms
Fraud detection systems are designed to protect your money, but they’re not perfect. Many alerts are triggered by behavior that simply doesn’t match your usual patterns. That’s why it’s important to understand how your money habits appear from a security perspective. By staying consistent, using secure devices, and avoiding high-risk behaviors, you can reduce the chances of a false fraud alert. In today’s digital banking world, awareness is your best defense.
