Over the past couple of weeks, we’ve discussed how scammers use certain tools to defraud victims.

In a recent post, we talked about the dangers of instant payment apps. We also followed it up with a post discussing how credit cards and checks are much safer.

However, it’s important to mention that “safer” doesn’t mean risk-free. These payment methods are not immune to fraud. Knowing how scammers can weaponize these familiar payment solutions can help you use them in a way that’s safe and doesn’t put your finances (or your peace of mind) at risk.

How Scams Work Using Checks and Credit Cards

One of the most common check scams takes advantage of federal “funds availability” rules. Under Regulation CC, banks are required to make at least part of a deposit available quickly—often the next business day, with most funds available within two business days. That availability can create a false sense of security.

This scam typically sees the perpetrator send the victim a check, which could be to cover equipment for a job, or transaction fees for a larger sum of money that the victim is promised. The scammer may also pretend to buy an item you’re selling online, send a check for extra, and ask you to return the difference.

A fake or altered check may appear to clear. But days later, the bank can discover it’s counterfeit and reverse the transaction. By then, the victim may have already sent goods, wired money, or refunded the “excess” from an overpayment scam, only to find themselves on the hook for the missing funds.

Credit cards offer stronger consumer protections, but they are not immune to fraud. Skimming devices at gas stations or ATMs can capture card data, which criminals then use to clone cards. Account takeover fraud is also on the rise, with scammers tricking victims into revealing login credentials through phishing emails or fake customer service calls.

The good news is that federal law limits your liability for unauthorized credit card use, provided you report it quickly. Still, resolving disputes can take time and effort, and merchants are often left absorbing the losses.

Stay Vigilant to Avoid Credit Card and Check Scams

The takeaway? While checks and credit cards are safer than instant payment apps, they are not foolproof.

Staying vigilant, monitoring accounts, and understanding how these scams work are key to protecting yourself. Never send money to someone you don’t know personally, always check card scanners carefully before using them, and report any suspicious activity to the appropriate financial and legal authorities.
