TAGIT electromagnetic (EM) security technology provides physical protection for sensitive information, valuable assets and merchandise across a wide range of security-sensitive environments. From protecting intellectual property and classified information to preventing library theft and reducing retail shrinkage, TAGIT provides specialized EM solutions for different security applications.
TAGIT EM security labels are available in more than 300 formats, including solutions for small and curved products, metallic surfaces, foil-packaged goods, books and other difficult-to-protect items. For libraries and archives, TAGIT also offers EM labels compatible with major library EM security systems, including alternatives to traditional 3M Tattle-Tape™.
TAGIT solutions are used across government and defense organizations, research facilities, universities, libraries, industrial environments and retail, providing physical security where digital protection alone cannot prevent the unauthorized removal of information or assets.
TAGIT EM security technology is used by retailers, libraries and security-sensitive organizations worldwide to protect valuable merchandise, assets and information. Our solutions support reliable protection across a wide range of applications, including challenging products and environments.
Yes. TAGIT EM EAS systems can detect EM security labels concealed inside aluminium foil and foil-lined booster bags. They also provide reliable detection of EM labels applied to metallic surfaces, curved products and small-format merchandise, helping retailers protect high-risk items that can be challenging for conventional EAS technologies.
Yes. TAGIT EM security labels are compatible with most standard EM EAS systems, including many existing and legacy installations. Compatibility with certain Meto EM systems depends on the system configuration and cannot always be guaranteed with standard EM labels.
For installations using both Meto and non-Meto EM systems, TAGIT offers dual-technology EM security labels designed to support both detection formats. This allows products to be labelled during manufacturing or at the distribution center (DC) for use across different EM EAS system installations.
Yes. TAGIT EM EAS systems can detect suitable EM security labels applied to many products with metallic surfaces or metal-containing packaging. This makes EM technology suitable for protecting merchandise that can be challenging for conventional EAS solutions.
Detection performance depends on factors including the type and amount of metal, EM label type, label placement, system configuration and the installation environment. Strongly magnetized materials may interfere with the electromagnetic response of the label and reduce detection performance.
For specialty retail and other security applications, TAGIT offers a range of EM label formats designed for small, curved, metallic and other difficult-to-secure products.
The most suitable EM security label depends on the size, shape, material and packaging of the product.
Larger products typically benefit from longer EM labels, which provide a stronger signal and can support greater detection range.
Smaller or space-constrained products may require compact, high-performance formats such as TAGIT Twin Labels or Power Labels, designed to provide strong detection performance within a smaller application area.
For challenging products, including curved surfaces, metallic items and complex packaging, the appropriate label type and placement are particularly important.
TAGIT offers more than 300 EM label formats and can recommend the most suitable EM security label based on the product, application and security requirements.
The return on investment from a TAGIT EM EAS system depends on factors such as store size, product mix, theft and shrinkage levels, system configuration and existing security measures.
TAGIT EM EAS systems can help retailers protect high-risk and difficult-to-secure merchandise, potentially reducing theft-related losses and improving overall loss-prevention performance.
Actual savings and payback periods vary by installation and should be assessed based on the specific retail environment and security requirements.

Some products can be more challenging to protect with EM EAS technology. Strongly magnetized materials may interfere with the electromagnetic response of an EM security label and reduce detection performance.
TAGIT EM EAS technology can be used across a broad range of retail, library, document-security and asset-protection applications, including many small, curved, metallic and other difficult-to-secure items.
The suitability of EM protection depends on the product material, size, label type and placement, system configuration and installation environment. For challenging applications, TAGIT can recommend an appropriate EM label and system configuration.
Environmental noise interference in electromagnetic (EM) EAS systems can be caused by nearby electrical equipment or infrastructure that generates or distorts electromagnetic fields, potentially affecting detection performance and system stability.
Common sources may include:
Air-conditioning systems and electrical equipment
Computer equipment and IT infrastructure
Certain lighting systems
Other EM EAS systems operating nearby, including some legacy installations
Electromagnetic interference can affect EM EAS installations generally and is not specific to TAGIT systems.
TAGIT EM EAS systems use advanced digital signal processing (DSP) and system tuning to support stable detection performance in electrically challenging environments. System performance depends on the installation environment, antenna configuration, system tuning and EM label type.
If environmental noise cannot be sufficiently reduced, detection performance can be optimized through system configuration and tuning, including:
Master–Master configurations – Can improve detection performance and system stability in electrically challenging installations.
Sensor-based tuning and calibration – Enables fine adjustment of detection settings according to the local electrical environment.
These approaches can help maintain stable EM EAS detection performance in environments with persistent electromagnetic interference or complex installation conditions.
TAGIT EM EAS systems support variable aisle widths depending on the installation environment, electromagnetic noise levels, antenna configuration, system tuning and the EM security labels used. Lower electromagnetic noise and optimized system configurations generally allow wider antenna spacing while maintaining reliable detection performance.
TAGIT is also developing the i30 wide-aisle EM EAS system, designed to support aisle widths of up to 1.4 meters under suitable installation conditions.
Detection range and aisle width can be further improved through the right combination of EM label selection, antenna configuration and system tuning. Longer or higher-performance EM labels can increase detection range, while optimized antenna configurations and site-specific calibration can improve overall system performance.
Environmental electromagnetic noise also plays an important role: lower-noise conditions generally allow wider antenna spacing while maintaining reliable detection performance.
