Finding Your Next Counterfeit Bill Detector: A Buyer's Guide

We know all this information can be overwhelming for you. With the existing fear of being ripped off by a fake bill, you wouldn’t want the additional burden of choosing the right counterfeit detector. This buying guide will walk you through everything there is o know about fake bills and identifying them.

How Do Counterfeit Detectors Detect Fake Bill?

There are multiple ways in which a detector marks a bill as fake. A bill detector marker has an ionized ink that turns dark on a fake bill. Often, the bills are a high-quality replica and may pass an ink test; this is where the UV Light comes into play. A detector with a UV Light sensor can help identify a note to be authentic if it glows in this light. In an advanced detector, a magnetic sensor helps identify the magnetic ink and metal threads used in real bills.

Types of Bill Detectors

Counterfeit currency is a big problem for businesses that take their revenue in cash. It negatively affects the profits of a business. Counterfeit bill detectors can be used to identify fake currency.

Below are three types of counterfeit bill detectors commonly used to detect fake currency:

UV-light counterfeit detectors

UV-light counterfeit detectors are a very reliable tool for detecting fake money. When the bill is placed under the UV light, its security thread and other ultraviolet markings are highlighted. By checking these highlighted features, it can be determined whether the currency is fake or not.
Moreover, you can use this UV Light detector to scan other important documents like passports and credit cards.

Counterfeit detector pens

Counterfeit Detector Pens utilize an iodine-based ink that reacts with wood-based paper. The ink turns dark upon contact with a counterfeit bill made using this type of paper, allowing you to identify it as fake. These pens are designed for those with a low budget who want something on the go. They come with adult gold ink that stays the same on real bills and darkens when on a fake bill.

Magnetic detectors

A detector with a magnetic sensor helps identify the usage of magnetic ink on bills and the metal threads placed on real banknotes. These metal threads are strategically placed on each bank denomination and have different colors. A magnetic sensor can help identify this strip, which is the main feature of a real bill.

Watermark detectors

A real banknote comes with a watermark that the naked eye cannot see. But with detectors with watermark sensors, these can be seen under the light, thus differentiating a fake bill from the real one.

Bill size detectors

Even though a counterfeit product is a replica of a real bill, the size detector can help identify even the smallest differences in size.

Multi-test intelligent currency scanners

Multi-test intelligent currency scanners are the best tool for detecting fake bills. These devices conduct several different types of tests to determine the authenticity of a bill. They are fast, reliable, and easy to use, perfect for detecting counterfeit currencies. They can be used for various currencies and are often packed with counting abilities.

How to Choose a Bill Detector

Being scammed is truly a curse. With so many options in the market, you want a bill detector that best fits your needs. Here is how you can choose a bill detector.

Budget

The technology of identifying counterfeit money bills comes in multiple varieties and the more sophisticated the technology gets the more the price increases. A counterfeit detector marker will do the job if you have a low budget. But if your pockets can bear the expense, a multi-purpose detector would be the best bet.

Cash inflow

If your business has a huge inflow of cash daily, you would need a prompt and thorough detector. Checking each bill with a marker won’t work for you in this case, and you would have to opt for an automatic detector.

Footfall

If you have a busy schedule at your store where there are many people, you would need a quick detector. However, if you have a low footfall in your store, a basic counterfeit detector marker would do.

Types of Currency

Often at times, detectors do not work on a few currency bills. If your business requires different currency bills, you would want to opt for a detector with advanced technology rather than a basic detector marker.
