IBao location tracker is a kind of elderly friendly service. It is a location tracker with the aims of providing updated locations (indoor and outdoor) of the elderly with dementia. Family members can trace the trail of the elderly and set safety boundary in the mobile iBao App to prevent them from wandering. Wing Wah also places health measurement tools in the co-operated NGOs' elderly centers in which the elderly can use the iBao as an identity to have measurements of body temperature, weight, blood pressure and blood sugar. All these health data will be stored in the mobile iBao App. The family members, carers and the NGOs' staff can help to take remedial actions when necessary.
