As people age, their memory fade, and this causes many elders to lose their ways home.
Footsprint is designed to solve this problem. When seniors leave home wearing Footsprint, it will leave traces of number coded ultra-violet fluorescent ink footprints.
Footsprint also guides seniors by blinking when they are retracing their steps home.If an elder fails to return home for an extended period, his/her family can enter their loved one’s Footsprint code in their smartphone Apps, they will then be able to find the missing elder by tracing their footprints.
