RF vs AM – what’s the difference and why that’s relevant to your business
Both RF (Radio Frequency) and AM (Acousto-Magnetic) EAS systems protect merchandise by creating a detection field at store exits. When an active tag passes through the field without being deactivated, the system triggers an alarm.
Customers and retailers don’t want the gates to be visually prominent; the focus should remain on the products. Detection distance directly affects entrance design, customer flow, blind spots and overall security performance.
RF Technology
RF systems typically operate at 8.2 MHz and detect RF labels or hard tags as they pass between the antennas. RF is widely used due to its cost-effectiveness and compatibility with disposable paper labels.
- Generally lower hardware and consumable costs
- Ideal for high-volume RF paper labels
- Best suited for grocery retail
- Shorter detection distance between gates
- More sensitive to environmental interference
AM Technology
AM systems operate at 58 kHz and use a resonating magnetic response from the tag. This technology delivers exceptionally stable detection, even in challenging retail environments.
- Significantly wider detection distance
- Ideal for wide or high-traffic entrances
- Reduced risk of blind spots
- Excellent performance in demanding layouts
- Although generally a higher cost per gate, fewer gates are often required in larger entrances
- Generally higher cost on DR labels
Security that supports the shopping journey
In fashion retail, the entrance should feel open, intuitive, and effortless. Customers expect clear sightlines and a natural flow into the store — not visual obstacles that break the shopping rhythm.
High-performance AM systems deliver wider coverage per gate. This allows large entrances to be protected efficiently, without adding unnecessary pedestals or compromising the store design.
Fewer gates — and a smoother customer experience.
How important is the first impression?
Customers decide how a store feels within seconds of walking in. A wide, open entrance feels premium and inviting — a crowded one does not. The EAS technology chosen directly impacts how many gates are required.
AM technology supports wider spacing between gates, so you can often protect the same entrance with fewer pedestals — improving flow, visibility, and the overall first impression.
LINDEX — a stronger case for AM gates
With fashion retail, the entrance should feel open, premium and effortless. Gate choice matters because it affects the number of pedestals, the perceived width of the entry, and the customer flow.
A high-performance AM system allows wider spacing while maintaining reliable detection — meaning you can protect a wide entrance without turning it into a “barrier”.
Correct technology — wrong execution
This store has chosen AM technology, which is the right direction for apparel. However, the gates are not powered — something experienced thieves quickly recognise.
In addition, this AM system still requires a centre gate. With a high-performance solution such as Cross Point, the same entrance could have been protected using just two powered gates, positioned at the sides.
Another retail entrance — fewer gates, better welcome
In this store entrance, three pedestals were installed to cover the width. That creates a tighter visual entry and can distract from the product experience.
With the right EAS technology allowing wider spacing, the same opening could be protected with just 2 gates — one either side.
Another entrance example — 2 gates would be enough
Here, the entrance is protected using 3 gates. With wider spacing and the correct AM solution, the same opening could be covered with 2 gates — one positioned on each side.
Leading brands are standardising on AM systems
Global retailers are increasingly choosing AM technology because it delivers wider gate spacing, higher detection reliability, and fewer visual barriers at the entrance. The result is stronger protection without compromising store design, customer flow, or the overall shopping experience.
“Thieves with keys” is now a real problem
Powerful detacher magnets designed to defeat retail security are widely available online. No authorisation. No accountability.
Magnetic locks are an outdated approach. Many retailers are moving to smarter systems that remove this vulnerability.
InVue’s OneKEY is the answer
OneKEY uses infrared communication instead of magnetic release — meaning it cannot be defeated by magnetic attacks.
Eliminates a known attack method
Removes the weakness of magnet-based solutions by design.
Security without sales friction
Instant staff access that keeps customers engaged and the store flowing.
Simple and globally proven
A clean, efficient system used worldwide across leading retailers.
InVue’s OneKEY — more protection, less friction
Traditional magnetic retail security has a real weakness: powerful detacher magnets are widely available and can defeat many legacy solutions. OneKEY removes this risk by design — it uses infrared communication instead of magnetic release, so magnets simply won’t work.
Result: stronger protection, faster daily operations, and a smoother customer experience — without “lost key” chaos.
Key benefits
- Magnet-proof: infrared communication means detacher magnets can’t defeat the system.
- No more lost-key risk: keys can be managed centrally and disabled if missing.
- More efficient staff workflow: faster access, fewer delays, less “call for help”.
- Lower security risk: reduces common attack methods and uncontrolled access.
- Better customer experience: products stay accessible — less locking, less friction.
More efficient
Speed up staff access and reduce interruptions — smoother ops, fewer delays, better flow.
More protection
Eliminate a common attack method and reduce the risk of uncontrolled access in-store.
Less risk
No more “lost key” headache — keys can be managed and disabled to maintain control.
