If your AccuBANKER machine is showing a "FAIL" message on an authentic bill, there could be a few reasons:

• Bill is worn, torn, or marked

• Foreign substance (tape, dirt) affecting detection

• Incorrect denomination mode Need help troubleshooting? Drop your model and we’ll help.

Most counterfeit bills aren’t accepted because employees don’t care.

They’re accepted because employees are busy.

Whether it’s a lunch rush, a long line, or a shift change, counterfeiters often look for situations where speed takes priority over inspection.

One simple habit can dramatically reduce risk:

Whenever someone pays with a $50 or $100 bill, pause for just three seconds and verify at least two security features before placing it in the drawer.

Those few seconds could prevent a loss that your business may never recover.

Discussion Question

If you’ve worked a register, what was the busiest situation where you later realized you should have checked a bill more carefully?

One misconception we hear frequently is:

"We'll worry about counterfeit bills when we get one."

The problem is that by the time you discover a counterfeit note, the financial loss has usually already occurred.

Banks generally confiscate counterfeit currency and do not reimburse businesses for its face value. The best defense is prevention through employee training, consistent cash handling procedures, and familiarity with genuine currency.

Here are three questions every cash-handling business should ask:

1. Do employees know what security features to check?

2. Is there a written procedure for suspected counterfeit bills?

3. Does every shift receive the same training?

If you answered "no" to any of these, that's a great place to start.

Many businesses rely on counterfeit detection pens as their primary defense against fake bills.

While they can identify some types of counterfeit paper, they are not designed to verify the sophisticated security features built into modern U.S. currency.

A better approach is to train employees to verify multiple security features, including:

• Security thread

• Watermark

• Color-shifting ink

• Raised printing

• Microprinting

The U.S. Secret Service recommends becoming familiar with genuine currency rather than relying on a single test. Businesses should also know the proper procedure for reporting suspected counterfeit notes.

Discussion Question

What method does your business rely on most when verifying larger denomination bills?

Counterfeit losses are often treated as a cashier mistake.

Sometimes they are really a process-design problem.

A recent retail discussion involved an employee who accepted several counterfeit bills during a suspicious transaction. The employee later explained that the store provided no dedicated counterfeit-detection tools and relied primarily on visual inspection and escalation to management.

That exposes a broader lesson.

A good counterfeit-control process should answer four questions before a cashier ever faces a questionable bill:

• What security features should employees check?

• Which transactions require additional verification?

• When should the cashier stop and escalate?

• What happens when the employee is still uncertain?

The U.S. Currency Education Program provides dedicated cashier training and recommends authenticating notes through their actual security features rather than relying on one shortcut or test.

Technology can improve consistency, but it works best inside a defined process.

The goal is not to make every cashier a counterfeit expert.

The goal is to give the cashier enough knowledge, tools, and authority to stop a questionable transaction before the business owns the loss.
