Magnet Detection

Magnet and Metal Detection

Booster Bag Detection: Hyperguard

Detects booster bags and stops shoplifters before they can make their move.

Since 1999, over 100,000 Hyperguard devices have been deployed by retail chains worldwide to detect booster bags used by habitual thieves. This proven solution, patented and made by our partners at Alert Systems in Denmark, not only successfully detects foil-lined bags used in shoplifting, but thanks to its advanced algorithms it virtually eliminates false alarms from moving doors or shopping carts.

Hyperguard is available as a standalone pedestal, or it can be integrated into an EAS system, adjusting itself automatically to either AM or RF EAS environment.

Hyperguard uses Cat5e cables for easy installation, and can push power from the controller to up to 11 antennas.  The hardware is made in Europe of high quality materials.

What’s a booster bag?

A booster bag is a shopping bag lined with tin foil, used by shoplifters to steal merchandise without getting detected by the store’s anti-theft (EAS) systems. The shoplifter brings the bag into the store, and fills it with merchandise. The merchandise often has anti-theft tags attached to it somewhere that would normally get detected by the anti-theft antennas at the store entrance, triggering an alarm. But the tin foil lining blocks the signal from the antennas, allowing the shoplifter to carry out the theft unnoticed. Hyperguard prevents this scenario by detecting the booster bag itself as soon as the would-be thief walks into the store.

Magnet Detection: Apparelguard

Detects metal detachers and catches the shoplifters in the act.

Apparelguard uses a patented double-detection system to alert store staff that an illegal detacher is present in the store. Typically installed in the fitting rooms, the Apparelguard senses magnetic motion coming from an EAS tag being removed by the shoplifter, giving the store staff an opportunity to prevent the theft while the merchandise is still in the fitting room, far from the store exit.

Apparelguard is easy to install and maintain, and its software allows for tuning to different types of magnetic detachers, providing wide protection.  It uses 3 dry relay contacts as alarm outputs, for light, sound, pager or CCTV. Additionally, API integration with an existing EAS controller is also available.

Apparelguard uses Cat5e cables for easy installation, and can push power from the controller to up to 11 antennas.  The hardware is made in Europe of high quality materials.

How are magnets used in shoplifting?

Retailers that use EAS (anti-theft) tags on their merchandise, need to remove them at the register when an honest shopper completes the purchase. Typically, a specialty magnetic detacher is used for this purpose, which the retailer gets from their security technology partner, like CONTROLTEK. Thieves sometimes obtain these detachers by stealing them or by buying them from irresponsible sellers. Armed with a detacher, a shoplifter can remove the security tags while in the store, then walk out without triggering the anti-theft alarm at the door. The Apparelguard can prevent this problem by detecting the illegal magnets in the fitting rooms, where the shoplifters usually try to remove tags.

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.
