For years, stores relied on a simple model: put a tag on an item, install pedestals at the door, and react when something beeped. That traditional EAS model no longer holds up against today's environment — where theft is faster, more organized, and often intentional.

The acronym RFID stands for Radio Frequency Identification. It’s a type of technology that has a similar function as a barcode: it is used to identify objects (or animals, or people). Whereas a barcode is printed on a sticker or product packaging that can be scanned using an optical scanner, RFID uses what’s called an inlay inside a label or plastic tag, and is “scanned” (actually read) by a reader that uses radio waves. RFID labels may look exactly like barcode labels or price stickers.
