I investigate fraud for a living, which means following transactions, chasing clues, and asking, “How did that get there?” 

One word comes up a lot: ACH. And no, ACH is not a suspicious guy named Ach hanging around your checking account. Promise. 

ACH stands for Automated Clearing House, a system that electronically moves money between bank accounts. Paychecks, mortgage payments, bills, and transfers can all travel by ACH. 

So, what exactly is ACH? 

Think of ACH as a highway for money. Instead of writing a check or handing over cash, funds move electronically from one financial institution to another. 

You may see ACH transactions when you: 

• Receive a paycheck, government payment, or other direct deposit 
• Pay a loan, utility bill, or other authorized payment 
• Transfer money between financial institutions 

ACH itself isn’t the problem. Trouble starts when someone gets your account information and uses it to move your money without permission. That is where my job gets interesting. 

When ACH goes from ordinary to suspicious 

Fraudsters may text, call, or email while pretending to be IHMVCU or another company you trust. Their goal is simple: get information they can use to access your money and possibly create an unauthorized ACH transaction. 

You might spot an ACH withdrawal with an unfamiliar company name, an unexpected amount, or no connection to anything you authorized. Stop and take a closer look. 

A transaction you don't recognize? Don't panic. Investigate. 

My biggest advice: if something looks wrong, tell us. An unfamiliar transaction isn’t always fraud because a payment processor or parent company may appear under a name you don’t recognize. 

But if you truly do not recognize it, let us investigate. Do not wait and think, “Maybe I’ll figure it out later.” Fraud is easier to address when we hear about it quickly. 

Your best fraud-fighting tool? You. 

You don’t need a badge or magnifying glass. A few simple habits can make a big difference: 

• Check transactions regularly. A quick scan helps you spot what belongs and what doesn’t 
• Turn on account alerts. They can flag activity you weren’t expecting 
• Question unexpected calls, texts, and emails. Never rush to share account details, passwords, or verification codes. 
• Do not click first and think later. If a message creates urgency, contact IHMVCU directly using a trusted number or website. 
• Report suspicious activity quickly. We would rather check a legitimate transaction than have you ignore one that isn’t. 

One last thing from your friendly neighborhood fraud officer 

Fraudsters are creative. They change tactics, stories, and even transaction names, so know your money and keep an eye on your accounts. 

ACH is not the bad guy. Trouble starts when someone moves your money without permission. Trust your gut and ask us when something feels off. I would rather investigate a false alarm than a stolen paycheck.
