Counterfeit Money Detection Equipment

Counterfeit Money Detection Equipment

Businesses in every industry are under the constant threat of receiving counterfeit money in exchange for goods and services. As you know, the government will not exchange counterfeit bills for real ones, and any losses associated with counterfeit currency must be written off as a loss due to theft. According to data compiled by the United States Department of Treasury, roughly $70 million in counterfeit bills are in circulation within the country. Protecting your bottom line means investing with a counterfeit money detection equipment company manufacturing the latest technology in detecting false bills. CONTROLTEK is known throughout the business world as the industry’s leading developer of counterfeit money detection technology, and offers a variety of products to help businesses improve their security.

Counterfeit Money Detection by CONTROLTEK

CONTROLTEK offers counterfeit money detection equipment for organizations that handle both large amounts of cash such as vaulted content, as well as smaller amounts of currency. Our solutions enable us to help our clients improve their counterfeit money detection operations, and we offer monetary counterfeit detection products for companies that are new to this security arm and are looking to learn more as they protect their bottom line. The majority of counterfeit bills made in America are $20 notes, and most counterfeiting rings in Europe produce $100 notes. Being able to keep these bills out of your internal circulation is critical to your company’s security and growth, so we offer counterfeit money detector pens and machines that help to weed out any unlawful notes.

Currency Authenticator Machines

CONTROLTEK understands that currency authenticator machines need to be easy to use and reliable, and that’s why we created the UVerifEYE Currency Authenticator for organizations handling large or small amounts of money. Many of our customers ask, how do currency authenticator machines work? Fake note detection is possible thanks to amplifier and comparator, UV LED, and photodiode technology. UV rays are transmitted by a UV LED source. If the currency is authentic that the note’s material will absorb a certain amount of the UV rays, and if the note is counterfeit then the UV rays will reflect up to the photodiode. Counterfeiters are not able to produce notes that can fool this technology, and when you call CONTROLTEK to learn more about the UVerifEYE Currency Authenticator, we can recommend how many units to purchase based on the amount of cash movement that come sin and goes out of your facilities.

The Best Counterfeit Detection Pen is the D-TEK

Organizations that handle smaller amounts of cash, or that have point of sales locations, will invest in a reliable counterfeit detection pen to place at every location where cash is received. The best counterfeit detection pen will contain an iodine solution that reacts with the starch molecules contained in the standard wood-based paper, leaving a dark brown smudge–a clear sign that the bill is a counterfeit. The linen and cotton fibers in actual currency will not react with the iodine solution, and therefore no visual change will occur on the note.

There are certain visual cues one can take away from holding bills up to the light in order to determine if they are real or fake. However, this places a great deal of strain on employees, and the repetitive action causes fatigue and as a result human error is common. Using a counterfeit detection pen is a fast, reliable way to search for fake notes while protecting your organization’s reputation and profitability.

Invest in the Best Currency Counter Cleaning Cards

Currency counter cleaning cards by CONTROLTEK have a patented design that cleans all surfaces around the rollers and belts, as well as the note recognition lenses in order to remove debris and particles enabling machine accuracy. One form of internal theft that companies face is when employees tamper with currency counters to mask the true number of bills being counted. This can be done by sprinkling fine lead particles from pencil shavings, or other similar types of debris. By regularly running currency counter cleaning cards through your equipment, you can significantly reduce this security threat, while simultaneously improving accuracy and productivity.

Retail Cash Security

The Best Cash Handling Procedures Retail Stores Perform Include Cash Bags

When it comes to loss prevention, having the right retail cash bags in your money-handling process will improve revenue management and save your company a great degree of time and money. In the retail industry “cash handling” is a common item that’s always being talked about. All levels of the business, from the individual store employee all the way up to corporate C-suite members, everyone knows the value of efficient and effective money management and cash handling.

Heap of hundred Dollar Bills

In the world of retail, it is easier for money handling to slip through the cracks, compared to other industries such as banking. CONTROLTEK understands the needs that concise with retail cash handling, and for more than 40 years we have been helping our clients understand the biggest challenges in the world of retail, and have responded as the leading company designing the best cash bags for retailers that enable retail brands to streamline their internal processes, better secure cash, allow quicker processing for your bank, and prevent internal or external tampering.

Tamper Evident Bags Used in Cash Handling Procedures Prevent Theft, and Should Be Easy for Employees to Use

According to statistics, 95% of retail businesses experience small cash theft and the average business loses thousands of dollars every year. In fact, three out of four retail employees admitted to stealing cash from their employer, and 30% of these cases carry on for more than five years. Tamper evident bags for retail stores help detour would-be thieves, and play a huge impact on improving cash handling procedures and improving revenue loss prevention.

CONTROLTEK has designed a number of tamper evident cash bags for retail stores. To date, the most popular retail cash bags would be the SafeLOK cash bag, which provides an ideal balance between ease of use and security–two critical things to have when employees are still in the training process. The technology behind this bag makes it easy for new employees to use while offering our patented security features that alert to a theft attempt. The SafeLOK retail cash bag has our own Press2Lok technology that makes the bag easy for employees to open and close, once they are taught how to handle the product.

What Features Should Retailers Look for in Tamper Evident Bags for Cash?

There are several features retailers must demand in a cash bag, and CONTROLTEK included them all when they designed the SafeLOK cash bag. First of all, retail cash bags should have a simple press-to-seal closure system that makes cash handling a cinch for store employees.

As for alerting team members to tampering, the best retail cash bags use high-visibility void messaging alerts with cold temperature changes to the bag, or with chemicals. Bags should change colors when exposed to high heat. Thieves are able to open cash bags by exposing them to extreme heat, unless the bags are high-quality such as the ones produced by CONTROLTEK. For example, thermochromic ink in the bags turns red when exposed to heat.

Effective retail cash bags should also prevent thieves from cut-and-replace tampering. SafeLok offers printed line graphics on cash bags in a random printed pattern, making cut-and-replace tampering impossible not to notice by store employees. In addition, retail cash bags should have large barcodes and serial numbers for tracking efforts using CCTV, and have an anti-static liner that won’t cling to one’s hands or clothing, which speeds up internal efficiency with money handling. Finally, a good security border on retail cash bags will prevent cutting and resealing.

These are the features to look for in tamper evident bags for effective and efficient cash handling procedures retail managers and leadership teams should look for.

Cash Handling Procedures Retail Stores Should Incorporate Include Bags for Checks and Deposit Slips

One great way to speed up your bank’s processing pace and therefore making your finds available without a long wait is to invest in tamper evident cash bags that have separate pockets for deposit slips and checks. Human error by your make increases when cash is mixed in the checks and deposit slips. This is why CONTROLTEK designed the SafeLok VT (Vertical Twin)–a cash bag for retailers that has all of the same features as the SafeLok but with an added pocket for checks and deposit slips.

Tamper Evident Security Seals and Security Labels for Retail Stores

Retail theft is a serious problem faced by retail chains, superstores and grocery stores throughout the country. The National Retail Federation states that more than 45 billion dollars are lost every year due to inventory shrinkage. Shoplifting, internal theft, organized retail crime and fraud can have devastating effects on a retail store’s profit margins, and can also create a toxic work environment  for employees and leave customers with a negative shopping experience.

CONTROLTEK offers proactive strategies for identifying, tracking and combating retail crime. While we are known primarily for our core products, tamper evident security seals and security labels are, unfortunately, often overlooked by retail management security and management teams, but they are much-needed. Retailers recognize that CONTROLTEK is the best company offering security seals and security labels for retail stores, and we always evolve our products to keep current with modern technology and national inventory shrinkage data, ensuring we offer our clients the best products and value within the landscape of retail security products.

What Types of Tamper Evident Security Seals are Available to Retailers?

Tamper evident security seals, such as our j-Lok Pull 8’’ Pull-tight Seals are important anti-theft products that come with a built-in tear-off feature requiring no tools or special training for removal, and they have a small strap diameter making them ideal for machines with smaller sealing apertures. These seals are used in a wide variety of retail applications, as well as C-TPAT and logistic circumstances. Our tamper evident security seals come in a variety of colors that include white, yellow, blue, green and red allowing team members to use them for coding and organizational purposes. Furthermore, each one is numbered and has a barcode to meet a wide variety of needs, and they come in a number of styles.

Another popular type of tamper evident security seals designed by CONTROLTEK is the m-Lok Padlock Seal. These seals are numbered tamper evident security seals, in the padlock design, and meet the rigorous standards and approval of the U.S. Customs. Each m-Lok Padlock Seal has durable metal hasps allowing it to withstand any abuse that might occur in transit, and it is water-resistant giving it an extra layer of security. Each of these tamper evident security seals come with the option of barcoding, and they are individually numbered.

When it comes to tamper evident security seals for protecting cash being transported to and from Automated Teller Machines (ATMs), CONTROLTEK has designed the ArrowLok ATM Cassette Seals. Our ATM security seals attach very easily and quickly while deterring theft. These ATM security products are ideal for any setting where ATMs are operated. These tamper evident security seals for ATM use work quite simply, yet they are highly effective at preventing theft. The ArrowLok ATM Cassette Seals are a single piece made from heavy duty plastic where the capsule is affixed to a locking anchor by a durable thread. When the capsule is under pressure and the anchor is inserted, one cannot remove it without leaving a clear sign that the device was tampered with.

If you are looking for tamper evident security seals that are extremely durable and adjustable, our all metal construction cable seals are likely your best option. Each seal has a visible number that can’t be missed, along with a noticeable barcode for fast, simple detection. The cable is very easy to use and can be adjusted to fit a broad range of sizes.

These are only a few of the tamper evident security seals designed by CONTROLTEK. We have a number of types to fit any need, and our team of experts are standing by to help you choose the best security seals to meet your needs.

What are Security Labels?

There are many retail management teams that have yet to hear about security labels. In fact, many wonder how something as seemingly simple as a label can help deter theft. A security label is a type of sticker label that serves the purpose of improving a product’s security when it is applied. Security labels can act as a visual deterrent, and they can be used to trace and track an item’s location. Security labels can also be used to help prevent counterfeiting, and it also serves the purpose of proving that it (and therefore the product) has not been tampered with, as one can easily tell by looking at a security label if someone attempted to remove it.

CONTROLTEK’S tamper evident security labels have a number of retail uses, but they are also used by ATM machine operators and at gas stations. CONTROLTEK takes security labels to the next level; these tamper evident security products reveal a specialized void message when tampered with or removed. The majority of our clients that invest in our tamper evident security labels use them for file cabinets, drawers, ATM cassettes, fuel pumps, electronic equipment (like POS credit card machines), and other uses that span a broad range of industries. These security labels can be used on virtually any surface including, wood, metal, plastic, glass, and paper. Our security labels offer exceptional tracking with sequential barcodes and numbers that aid in making your internal team more efficient with their daily operations.
