Electronic article surveillance (EAS) systems, commonly used in retail settings like Target, employ various methods to deter theft. Some tags utilize an ink-based security measure, where a dye pack is ruptured if the tag is improperly removed. This visible marking deters theft and aids in identifying stolen merchandise.
These dye-releasing tags offer a strong visual deterrent, minimizing merchandise losses due to shoplifting. The prominent staining makes reselling stolen goods difficult, further enhancing their effectiveness. While not all EAS tags employ ink, those that do represent a significant advancement in loss prevention technology, complementing other methods such as alarms and RFID systems.
