Learn to identify signs of financial mismatches and malicious activity to keep your credit and identity secure.

Effective credit management requires vigilance for two types of "red flags": security threats from external bad actors and product suitability issues in which a card's terms detract from your financial health.
We’ll share the top credit card red flags you may notice as a consumer. That way, you can ensure your cards protect and enhance your financial life.
Credit cards aren’t one-size-fits-all. Here are several indicators that you’re using the wrong one:
You should use a credit card that rewards you for your normal spending. Otherwise, you won’t get much value out of the rewards program.
For instance, “if you travel often, a card with points or miles for flights, hotels, and rental cars can pull real weight. [But], if you mostly cook at home, a card with a high multiplier for dining out probably isn't your best move,” says Cole Williams, certified financial planner (CFP®) and founder of Vessel Financial Planning, LLC.
If you find your current card isn't paying off, learn how to get the most out of your credit card rewards by aligning your plastic with your actual lifestyle.
Some credit card issuers make it more challenging than others to access your rewards. Here are some tell-tale signs that the program is bordering on predatory:
Rewards that expire (often within 12 to 24 months of earning them).
Surprise blackout dates to book travel with miles.
Points that lose their value.
High minimum redemption thresholds.
“Check the fine print on how long your points or miles stick around before assuming they'll be there when you're ready to use them,” emphasizes Williams.
If your account has an annual fee, do you see a return on that investment through the card’s perks?
You're starting out in the hole before you've swiped or tapped once. Some cards easily justify their cost, [with] free checked bags or airport lounge access if you fly regularly. Others are basically glorified coupon books.
Subprime "Fee-harvester" cards can be even worse. They “may seem appealing to borrowers who have trouble obtaining credit, but these cards have annual fees, and sometimes monthly fees, without the benefits of typical credit cards, like cashback or rewards,” explains Tamika Howell, accredited financial counselor (AFC®) and founder of Organize Your Money.
Don’t forget about the annual percentage rate (APR) – potentially your card’s highest fee. “Carrying an interest-bearing balance wipes out whatever rewards you're chasing. Double-digit interest works against you, and it works remarkably fast,” points out Williams.
Before signing up for a premium card to escape a low-value one, research the value of credit card welcome bonuses to see if the initial perks outweigh the annual fee
If you have a secured or subprime card, your goal is likely to graduate to an unsecured account or one with more perks. “However, some issuers won't automatically upgrade you or even tell you when you're ready for something better,” Williams declares. “Check your credit progress through the three major credit bureaus at AnnualCreditReport.com for free, multiple times a year. When your score supports it, you shouldn't have to stay in a starter card any longer than necessary," Willliams adds.
Borrowers in these situations can look into credit cards at a local credit union. Some credit unions may have financial counselors who can help identify cards that you are eligible for and are unsecured or have a clear path to an unsecured account.
Fraudsters will go to great lengths to get their hands on your credit card information. Here are some tip-offs that your information has been compromised:
“Look for very small purchases, maybe even less than a dollar, as that can happen when a credit card thief is testing to see if the card is still active. They might run several of these transactions [in rapid succession] so that merchants trust the device they're on, or they might use this to test the card and then sell the card's information to someone else,” notes Louis DeNicola, fraud content manager at Persona.
A criminal may not buy a new computer or book a vacation the first time they charge your account.
You make a con artist’s life easier when you hand them your credit card information. But how do they convince you to do it?
“Phishing is a broad term for a type of attack when a scammer or fraudster tries to trick you into sharing personal or confidential information. Often, [they’ll] pretend to be an employee of a reputable company or government agency,” DeNicola points out.
For example, you might receive an email from a shipping company asking you to verify your address or to make a small payment to receive a shipment. In actuality, the scammer is stealing your information, including your credit card details. Smishing is simply a phishing attack via text message or SMS.
With the rise of artificial intelligence (AI), it’s become increasingly difficult to tell legitimate communication from fraudulent messages. However, your credit card company won’t ask you for confidential information via text. So, if the person (or bot) on the other end does, you know it’s an attempted scam. If you’re ever in doubt about the legitimacy of correspondence you receive, contact your credit card company directly to ask about the status of your account.
One other hallmark of a scam: Asking you to act immediately. The criminal may say you need to provide your information urgently to protect your account. “If you receive a message that makes you feel like you have to act quickly, scared, or even really excited, try to take a several-minute pause before responding,” DeNicola suggests.
Some fraudsters open new credit card accounts in your name (more on that in a minute). Others take over existing accounts.
Fraudsters may get your information from data breaches, malware on your device, phishing campaigns, or other means. Then, they log in as you and wreak havoc.
Signs your account has been taken over include, but aren’t limited to:
You get an unexpected password reset notification from your bank.
You see a new device has been added.
The two-factor authentication has been disabled or redirected to a different phone number.
There’s a surprising new authorized user on your account.
The mailing address, email address, or phone number on your profile has been changed.
You can reduce your risk of account takeover by using a strong password and an authenticator app instead of your phone number for two-factor authentication.
Gaining access to your existing account is one thing, but posing as you to open a new one is on a whole other level. Here are a couple of giveaways that you’ve become the victim of identity theft:
Every line on your credit report should be familiar to you. When checking for potential identity theft, “Look for accounts that you don't recognize. These include loans, credit cards, and even collection accounts. Also, look for new hard inquiries that you don't expect because these are a record of when someone applies for credit,” DeNicola clarifies.
Combing through your credit report all the time can be overwhelming and tedious. Fortunately, technology can help. “If you have credit report monitoring (and there are many free options), you could receive a notification right away when someone applies for or opens a new credit card,” highlights DeNicola.
Your credit utilization ratio, or the percentage of your available credit you’re using, is a significant factor in calculating your credit score. Lenders generally like to see your utilization under 30%, but the lower, the better. If a fraudster maxes out an account tied to your credit report, your utilization ratio will skyrocket, and your score will likely drop.
Feature | Green Flag (Good Fit) | Red Flag (Warning Sign) |
Fees | Clear, annual fee offset by benefits | "Maintenance" or "Setup" fees with no perks |
Rewards | Aligned with your top 3 spending categories | Points that expire or are hard to redeem |
Reporting | Reports to all three major credit bureaus | Limited or no reporting to the credit bureaus |
Upgrades | Clear path to higher credit limits or better cards | Stagnant credit limits or no upgrade potential |
Follow these steps if you run into an emergency red flag situation:
Call your credit card company immediately for suspected fraud. The Fair Credit Billing Act limits your liability to $50 if you report the unauthorized transactions within 60 days of receiving your account statement.
Change the passwords on all your financial accounts and any account where payment information is stored.
Contact a credit bureau to request a credit freeze (no new accounts can be opened) or a fraud alert (extra identity verification will be required to open a new account) on your file.
File a report with the Federal Trade Commission (FTC) if your identity was stolen.
File a police report if your credit card issuer requires it to remove fraudulent charges from your account.
Dispute incorrect information on your credit report.
If you’re just using the wrong card, take a moment to think about what you need and want from your next account. Then, identify and thoroughly research several options before applying.
Pro Tip: If you’ve realized your current card is a poor fit, your first instinct might be to cancel it immediately. However, it’s important to understand how closing a credit card may impact your credit score before you pick up the phone.
Not necessarily. It's only a red flag if the value of the rewards and perks doesn't outweigh the cost of the fee.
Credit card factoring occurs when a business processes sales through another merchant’s account. It’s often a sign of high-risk or illicit activity.
Legitimate issuers will never ask for your full card number or password via text. If in doubt, call the number on the back of your physical card.
“A transaction might be declined if it doesn't match your usual purchasing patterns or if you try to make a very large purchase with a brand-new card. Sometimes this can also happen if you try to make a purchase when you're on a new device, such as a new phone or computer,” points out DeNicola.
“Social engineering is simply another term for psychological manipulation. [Unfortunately], you might not find out that you've been scammed until after you see suspicious transactions in your account,” DeNicola cautions.
