A security tag in clothes is a device used by shops to prevent theft. It is usually made of hard plastic and attached firmly to the garment so that it cannot be removed without special tools. These tags mainly work in two ways. Some are electronic article surveillance (EAS) tags, which contain a small strip or coil that communicates with sensors at the store’s exit. If the tag is not deactivated or removed by the cashier, it sets off an alarm when the person tries to leave. Others are ink tags, which contain small tubes filled with permanent ink. If someone tries to force the tag open, the tubes burst and spoil the fabric, making the stolen item useless.
Most tags also use a magnetic locking system with a ball-bearing mechanism that keeps them tightly fixed to the cloth. A strong magnet at the billing counter is required to unlock and safely remove them. By using these scientific principles—magnetism, electronics, and chemicals—security tags reduce financial losses for retailers and discourage shoplifters. For example, when you buy a shirt or jeans from brands like Zara, H&M, or Levi’s, you will notice a plastic tag attached near the seam or waistband. At checkout, the cashier removes it with a special detacher, and if not removed properly, it either triggers the alarm or damages the garment if tampered with. Thus, clothing security tags act as a simple yet highly effective anti-theft tool in modern retail stores.
