Investigators found a tracking tag hidden inside a stuffed toy at the woman’s home, leading police to believe the suspect used the tag to identify her residence. According to police data, consultations related to stalking cases involving tracking tags have been rising every year, reaching roughly 600 cases last year, marking a record high. Unlike traditional GPS-based tracking devices, which rely on satellite signals, these tags typically use Bluetooth technology and work by communicating with nearby smartphones. One man who enjoys motorcycle touring said he found a tracking tag attached to the back of his bike’s frame after hearing about similar incidents involving popular models. Experts say detecting hidden tracking tags is extremely difficult.
