According to Filip Technologies, the FiLIP 2 uses cell tower location and Wi-Fi triangulation to supplement GPS data, which can more accurately pinpoint a child's location in areas where GPS is limited.
Further enhancing its effectiveness, the FiLIP 2's cellular technology also enables parents and children to communicate with each other using two-way voice functionality to place and receive calls.
Further, PolyOne colorants bring the material to life with dynamic colors such as Superhero Blue, Watermelon Red, Limesicle Green, and Awesome Orange.
