Technology firms have apparently suggested placing tracking devices or a microchip under the skin of convicted criminals to monitor them in prison or when they come out, according to a recent report in the Guardian. Though the idea raises questions about human rights, the technology is certainly developing that could make such an initiative possible.
Electronic ankle bracelets are already widely used forms of this technology. They normally use a radio frequency connected to a base station, similar to your home WiFi, to ensure the device is within a specific range in or around the house. Others use GPS to monitor the location of the person. Such devices require regular charging, however.
