How Dome Ink Tag works？

Dome Ink Tag is an electronic tag commonly used to prevent theft. Its working principle is based on the design of a dyed ink capsule inside. The following is its basic working principle: Dome Ink Tag is often installed on labels of clothing or other goods. When the goods pass through the exit of the store, the sensors in the store will send electromagnetic waves of a specific frequency, and the electronic components inside the Dome Ink Tag will receive After receiving the electromagnetic wave signal sent by the sensor, the dye capsule in the label will be activated. The dye ink in the dye capsule is released and sprayed onto the product connected to the label. At the same time, the electronic components in the tag will also trigger the store's anti-theft system and sound an alarm to alert the clerk that goods have been taken out of the store without payment. Dye ink sprayed on an item cannot be removed, thus marking the item and making it unsaleable, thus preventing theft.
