Top 5 Ways Banks Detect Counterfeit Money in 2026
Counterfeit detection has evolved significantly over the years, and it’s imperative that banks and other financial institutions stay up to date on the latest and most effective detection equipment.
It might seem like a simple task, but there are many options to choose from, with different detection methods, capacities, sizes, and levels of reliability. The right detection tools ultimately depend on your operation and how cash is handled throughout your organization. After reading this article, you should have a better understanding of which counterfeit detection option best fits your operations.
Types of Counterfeit Money Detectors:
Ultraviolet (UV) detectors use ultraviolet light to revel hidden security elements on bills that you can’t see with the naked eye.
Magnetic (MG) detectors compare the magnetic properties found in genuine currency to the bill being tested.
Infrared (IR) detectors work similarly to magnetic detectors but instead compare the infrared characteristics of genuine currency.
Watermark Verification (WM) detectors compare embedded watermarks and security strips found in authentic currency.
Combination Detection Systems most commonly use a mix of UV, magnetic, infrared, and dimensional checks to give the most accurate readings, often above 99.9% accuracy. BankSupplies also offers a variety of other authentication combinations, outlined in Table 1.
Automatic Detectors, such as pens, provide quick authentication results during the counting process.
Ultraviolet (UV) detectors and counterfeit detections pens are the only authentication devices commonly offered as standalone products. On the BankSupplies website Magnetic (MG), Infrared (IR), Watermark Verification (WM) technologies are typically included as part of Combination Detection Systems only.
At BankSupplies, we offer an extensive selection of professional counterfeit detectors and bill counters with advanced multi-point authentication systems. Most of the counterfeit detectors available on our site are considered Combination Detection Systems because they verify multiple bill characteristics at once.
1. Combination Detection Systems
Combination detectors use multiple authentication methods to offer the highest level of accuracy. These detectors will be your number one choice if accuracy is your priority and portability is less important.
Single-detection options, such as ultraviolet (UV) pens, can be useful for portability and quick checks, but they may miss sophisticated counterfeit bills that advanced combination systems can detect.
The table below outlines the systems we offer and the authentication combination:

2. Ultraviolet (UV) Counterfeit Detection
The Ultraviolet (UV) detection systems work to spot fake cash but also work on counterfeit ID’s, credit cards, and passports. Modern currency and forms of identification often contain embedded UV-reactive threads that are extremely hard to reproduce. The UV counterfeit detectors work by exposing these threads that are not normally visible. So, if the markings are inconsistent or missing, the bill is likely counterfeit.
These detectors are especially common in bars, restaurants, and casinos, where one person is often in charge of both checking ID’s and cash transactions. However, they are equally effective in large-scale cash handling operations.
Ultraviolet (UV) detection is considered one of the most reliable counterfeit detection methods since it is nearly impossible to re-create the embedded threads in genuine bills. Even so, suspicious bills should still be verified using a second authentication method whenever possible.
Most Ultraviolet (UV) detectors available from BankSupplies are either part of a Combination Detection System or available in pen form. One exception is the Tri Test Counterfeit Detector with Plug, which combines ultraviolet (UV) thread detection, watermark verification using a white LED backlight, and a traditional DriMark counterfeit detection pen in one compact unit.
BankSupplies ultraviolet (UV) Counterfeit detection pens include:
| Item Name | Description | BSI SKU |
|---|---|---|
| DriMark UV Counterfeit Detector Light | Sturdy aluminum construction, heavy duty switch and electrical connections for years of trouble-free use | 701-60700 |
| DriMark Tethered UV Counterfeit Detector Light | Sturdy aluminum construction, heavy duty switch and electrical connections for years of trouble-free use | 701-60701 |
| DriMark Dual Test Counterfeit Detection Pens | Counterfeit detection pen with an Ultra Violet Light in the cap. | 701-17 |

3. Counterfeit Detector and Bill Counter
Counterfeit detection systems with integrated bill counting capabilities are sometimes criticized for prioritizing processing speed over authentication accuracy. These detectors are most effective when large amounts of genuine cash are being handled. However, having accuracy and speed in one device is increasingly important in banking or casino environments where a few counterfeit bills can be a big problem.
That’s why BankSupplies only offers bill counters with advanced Combination Detection Systems capable of verifying multiple security features simultaneously.
If you operate a smaller-scale cash business or do not require high-speed bill counting, a standalone combination detector may be the more cost-effective option. However, larger cash operations benefit significantly from automated counting systems that also verify authenticity during processing.
Below are four bill counters with advanced counterfeit detections available from BankSupplies:
| Item Name | Authentication Methods | BSI SKU |
|---|---|---|
| AccuBANKER® D700 Automatic Value and Counterfeit Bill Detector | Magnetic (MG), Ultraviolet (UV), Infrared (IR), Watermark (WM), Size (DD), Image, Color Spectrum | 701-00700 |

4. Manual Inspection
Experienced cash handlers such as casino attendants, bank tellers, and bartenders often handle enough currency to recognize counterfeit bills immediately. In many cases, they can identify a fake bill simply by the feel of the paper.
However, trained employees also look for:
• Raised ink texture
• Proper watermark placement
• Different serial numbers
• Correct security threading
• Sharp print clarity and color-shifting ink
Having trained and experienced cash handlers on staff is one of the best defenses against counterfeit currency. In many cases, human inspection can be even more reliable than relying only on counterfeit detection pens.
5. Counterfeit Detection Pens
Counterfeit detection pens are one-dimensional authentication tools that work by detecting the starch content found in standard bills. Unfortunately, sophisticated counterfeit bills have been known to pass this pen test. Because of this, counterfeit detection pens are best used in lower-volume environments where quick screening is more important than advanced authentication.
They are commonly used in restaurants, bars, concessions, and other quick-service environments where employees need a fast and inexpensive way to check bills.
BankSupplies offers a counterfeit detection pen with built-in UV functionality. The DriMark Dual Test Counterfeit Detection Pen features a dual-sided design with both starch testing and UV detection capabilities. It is available in both single-pack and six-pack options and can also be purchased in a tethered version for attachment to registers or counters.
In the table below are the Counterfeit Detection Pens with no UV light:
| Item Name | Description | BSI SKU |
|---|---|---|
| Dri Mark Counterfeit Detector Pen | When marked, the ink from the pen will react to the wood-based or fiber-based paper. | 701-50840 |
| Tethered Dri Mark Counterfeit Detector Pen | An amber mark passes the test, while a dark brown or black mark fails, meaning the bill is likely counterfeit | 701-50842 |
| MMF Counterfeit Detector Pen | Contains an iodine solution that reacts with the starch in wood-based paper to create a black stain. | 701-50855 |

Final Thoughts on Counterfeit Detection in 2026
Counterfeit detection is no longer just about using a simple pen or quickly checking for a watermark. As counterfeit techniques continue to evolve, banks and businesses need detection systems that combine speed, accuracy, and multiple layers of authentication.
The right solution depends on your operation. High-volume cash environments may benefit most from advanced bill counters with integrated counterfeit detection, while smaller businesses may only need a reliable UV detector or counterfeit pen for quick bill verification.
No matter the size of your operation, combining quality detection equipment with trained employees remains the most effective defense against counterfeit currency. By using a layered approach and investing in reliable authentication tools, your organization can reduce risk, improve transaction efficiency, and maintain confidence in every cash transaction.
