The TAGIT Rhombus Pro EM System (PrmL-RH) is TAGIT’s most advanced electromagnetic surveillance solution, engineered for the protection of classified documents, valuable assets, and sensitive media in demanding environments.
With its patented 3-coil rhombus design, the system delivers highly reliable tag detection across all orientations — including wall-facing, ceiling, and floor-level directions — ensuring consistent performance even in high-interference settings.
Rhombus Pro is ideal for use in:
- Libraries
- Government institutions
- Archives
- High-tech offices
- Research and corporate environments
It is fully compatible with TAGIT Secure Paper, which contains ultra-thin patented microwires embedded directly during production in the Czech Republic. These microwires serve as invisible, integrated EM tags, making the documents themselves electronically detectable — a powerful, non-invasive solution for securing classified records, sensitive publications, and intellectual property.
The system supports both harmonic and Barkhausen tag types, offers detection coverage up to 180 cm in height, and can be expanded with an optional floor antenna for full vertical zone protection.
Designed for institutions that demand maximum security with minimal intrusion, Rhombus Pro blends advanced technology with reliable detection performance — making it the top choice for both document-sensitive environments and modern library systems.
Yes. TAGIT 3D EM systems operate at low frequencies, enabling them to detect products even when hidden in aluminium foil or booster bags—techniques used to bypass traditional RF and AM systems.TAGIT labels also perform reliably on metal surfaces, rounded packaging, and small objects. Watch how
Yes, with one exception. TAGIT EM labels are compatible with all standard EM systems except Meto. For customers using both Meto and non-Meto systems, dual-technology labels are available that work across platforms—including tagging at DC or during manufacturing.
Yes. TAGIT 3D EM technology detects labels applied to metal objects—unless the metal is magnetized, which interferes with detection.
Larger products → use longer labels for stronger signal detectionSmaller products → use short or high-performance labels (e.g. Twin or Power Labels)
Longer labels generally improve detection range, and high-performance options boost results for difficult surfaces or formats.
TAGIT systems allow you to protect more high-shrink items than other technologies, leading to significant shrinkage reduction and a better return on investment.

Only items with magnetic properties cannot be protected.This limitation aside, TAGIT 3D EM is one of the most versatile and widely compatible EAS systems available.
Nearby devices such as air conditioners, computer monitors, special lighting, and Meto EM systems can introduce environmental noise. This is a known issue with all EAS systems—not unique to TAGIT.
If environmental noise cannot be reduced physically, you can optimize system performance using:
- Master-Master or Turbo configurations
- Sensor-based tuning
These allow fine adjustment to ensure maximum detection reliability even in challenging conditions.
TAGIT 3D EM systems can detect across aisle widths up to 1.15 meters with standard setups.
- Use longer EM labels where possible
- Upgrade to Turbo Mode or Master-Master configuration with sensors
- Apply high-performance specialty labels for critical items
These adjustments allow greater aisle flexibility and stronger detection performance.
