With the advancement of technology, there are more and more kinds of anti-lost items for the elderly, and GPS trackers are being used by more and more people. However, because of the ever-changing nature of these devices, when elders see something they don't recognize, they may refuse to use it or throw it away when they find it. To prevent the elderly from losing the tracker, it is advisable for family members to pack the tracker well before giving it to the elderly. One idea is to wrap the tracker as a peace sign and give it to the elder as a gift. Elderly people will recognize the talisman and will treasure it as a gift from their family and keep it with them.
