BRBuy anti-theft antennas that actually work
5th-generation RF or AM technology (8.2 MHz), plug-and-play, low power consumption and the longest warranty in the market: 24 months. With tags and accessories for every retail segment.
No monthly fee · No installation cost · Support in Portugal and Brazil
Every item that leaves without passing the till is profit that never comes back
External theft, internal theft and stock "shrinkage" eat into any retailer's margin. Without an electronic system at the door, the loss only shows up in the inventory count — by which point it's too late.
- Audible and visual alarm when an active tag passes through the antenna.
- Deterrent effect: a visible tag already reduces theft attempts.
- Products stay accessible on the sales floor — no need to lock everything in a display case.

Anti-theft tags: hard and adhesive
Hard tags (reusable)
Attached to the product with a pin or steel cable and removed at the till with a detacher. Ideal for clothing, bags, footwear and higher-value items. Impact-resistant and reusable for years.
Adhesive tags (disposable)
Stuck directly onto the packaging or product. Perfect for books, perfume, medication, cosmetics, meat and fast-turnover items. Deactivated at the till.
Accessories: checkout detachers and deactivators, steel cables (lanyards) to secure hard tags on irregularly shaped items, and category-specific locks.

Everything you need to know before buying
RF (radio frequency) is the most common technology in fashion retail, with lower acquisition and energy costs. Near metal and liquids it loses sensitivity — that's why supermarkets and pharmacies tend to use AM (acousto-magnetic). We recommend the right one for your product mix during the quote.
No. You buy the equipment and it's yours. There's no rental contract or monthly fee — only tag replacements as your store uses them up.
No. The antennas are plug-and-play and connect to a standard outlet. We guide you on positioning and calibrating the detection range. Simple installation, no building work.
Typically 0.9 m to 1.2 m after calibration, depending on the tag type and product. For wider gaps we use intermediate antennas or specific models.
Yes. Hard tags for clothing, bags and footwear; adhesive tags for books, perfume, medication, cosmetics and meat. There are accessories for irregularly shaped items.
