Electronic article surveillance for a small store

Electronic article surveillance is the tag-and-gate system: a tag on the product, antennas at the door, an alarm when an active tag passes through. It works, it is not cheap, and in a small-format store it earns its place on a narrow set of products rather than across the shop.

The decision is a margin calculation, not a security philosophy.

How does the system actually work?

A tag attached to the product responds to a field generated by antennas at the exit. Paying at the register either removes the tag or deactivates it. An active tag passing the antennas triggers an alarm. Electronic article surveillance systems come in several technologies, and the tags and the gates have to match.

That matching requirement is the first practical constraint. Tags from one technology do not work with gates from another, so the system is a commitment rather than a purchase.

What does a small store actually need to protect?

The items where a single loss costs real money and the category has a known problem. In a convenience or neighbourhood store that is usually a short list: high-value health and beauty items, certain accessories, batteries, and whatever your own shrink data says.

That last clause matters. Tagging what you assume is being taken rather than what your counts show is how stores spend money protecting the wrong shelf.

Why not tag everything?

Because tags cost money per item and time per item, and both scale. A hard tag applied and removed on every unit is a labour cost on every sale as well as every delivery, and at small ticket values that cost exceeds the loss it prevents.

There is also the customer experience. A store where every item alarms occasionally, and where staff spend the day removing tags, feels like a different kind of shop than the one most neighbourhood retailers want to run.

What about false alarms?

They are the reason systems get switched off. A gate that alarms on deactivated tags, on a customer's own previously-tagged purchase from another store, or on nothing at all trains staff to ignore it within a month.

An ignored alarm is worse than no alarm, because it costs money and provides nothing. If you install a system, the discipline is that every alarm is checked, politely and briefly, every time.

How should staff respond to one?

Calmly, and with a script. "Sorry, the gate went off — can I check the bag?" is a request, not a demand, and the customer can refuse. What staff must never do is detain anyone, block a door, or chase somebody into the street.

The moment you are considering accusing, searching or detaining a person, you are in territory governed by state and local law, and it is not a decision for a nineteen-year-old at nine in the evening. The rule should be written and it should be conservative.

What are the cheaper alternatives?

Locking cases, which stop the theft and most of the sales in the same motion, so reserve them for items whose loss rate has earned it. Moving high-risk items into the cashier's direct line of sight. Reducing facings so a sweep is less rewarding. And keeping the store's sightlines open.

All of those cost less than a gate system and several of them help sales rather than hurting them. Fixtures and cases sit in the store supplies range.

How do you know whether it worked?

By measuring the category before and after, which means you need a before. Count the protected categories for a period, install, then count again on the same cycle.

A store that installs a system and then cannot say whether shrink fell has bought a feeling. The measurement is not difficult and it is the only thing that justifies the next purchase.
