IOT system to track children and dementia elderly
I like to propose an IOT (internet of things) system to track young children and elderly suffering from dementia.

We can install a network of 20,000 blue tooth beacon readers all over Singapore - at bus stops, HBD blocks and public buildings. 

Families can buy the blue tooth beacons (cost about $5 to $15 each) and give to young children or dementia elderly. These beacons can be worn in a wrist band or attached to a bag. The battery in the beacon can last for 6 months or longer. 

When the holder passes any of the 20,000 readers, the data can be stored in a cloud server. 

The family can track the location of the beacon holder when the need arises, e.g. when a child or elderly is lost. This information is available only to the family and adequate safeguard can be implemented to prevent the data from being accessed illegally. In any case, the data is of no interest to third parties.

The cost of purchasing and installing the 20,000 readers should be about $3 million. However, the building and bus stop owners should be asked to install the readers and to provide the electrical connection.

There will also be the cost of providing the data connection for the 20,000 readers. At $5 per month, the cost will be $100,000 or $1.2 million a year.

Managers of shopping malls have the choice of installing additional readers in their malls to allow customers to find the location of family members. 

The location of each beacon holder will be the last location that is read by a reader. The holder may have moved away from that location but has not been captured by another reader. He or she should be in the vicinity.

Would this be a useful Smart Nation project?
