Acousto-magnetic (AM) Electronic Article Surveillance (EAS) tags are a common anti-theft technology used by retailers to protect merchandise from shoplifting. These tags, attached to products, trigger alarms when passing through antennas positioned at store exits. Understanding how AM EAS tags work and their key features can be helpful for both retailers and shoppers.
Here’s everything you need to know about AM EAS tags:
How they work:
- AM EAS tags contain a resonant circuit tuned to a specific frequency (usually 58 kHz).
- When passing through the AM EAS antenna, the antenna emits a radio wave at the same frequency.
- This induces a current in the tag’s circuit, causing it to resonate and amplify the signal.
- The amplified signal is picked up by the antenna, triggering an alarm if not deactivated.
Types of AM EAS tags:
- Hard tags: Attached to merchandise with pins or adhesive, typically used for high-value items.
- Soft tags: Made of paper or fabric, attached with adhesive, good for textiles and other delicate items.
- Labels: Adhesive stickers applied directly to products.
- Detection range: Varies depending on antenna and tag strength, typically several meters.
- Tamper-proof: Tags can be designed to break or trigger alarms if tampered with.
- Deactivation: Tags can be deactivated with special devices at checkout counters.
- Reusable: Hard tags and some labels can be reused on different items.
Benefits for retailers:
- Reduce shoplifting: Deter thieves and discourage shoplifting attempts.
- Increase profits: Protect merchandise and reduce shrink.
- Improve customer experience: Open merchandising with fewer security barriers.
Considerations for shoppers:
- Alarms: If an alarm sounds, cooperate with store staff to resolve the issue.
- Deactivation: Ensure tags are deactivated properly before leaving the store.
- Removal: Do not attempt to remove tags yourself, as it may damage the product and trigger an alarm.
- AM EAS is one of several EAS technologies, each with its own advantages and limitations.
- AM EAS systems require regular maintenance and calibration for optimal performance.
- Some concerns exist about potential interference with medical devices, though modern systems are designed to minimize this risk.
