Older Sibling is a tracking service that will let you learn about the location of any person who has a device with a Bluetooth chip. To use it, you need to get the software that is provided on the site, and enter the ID from the Bluetooth chip that you intend to track.
In case you wonder how you can get that information, you needn’t worry – you can have Older Sibling extract the chip’s info for you.
Because Bluetooth is a short range technology, you will only be able to detect the device if it is near your computer. That is, whenever the device moves within range you will know about it. A service like this one, then, will be perfect for determining which time your teenage son or daughter got back home, since the data is saved as part of a log.
Besides, you can instruct Older Sibling to send you a text message when the device was detected. In that way, if your son came home several hours late and you fell asleep while you waited for him to come your chances of waking up and having a word or two with him right as he is sneaking in are increased.
