Oh, that? That's my PAL
Forbes - For real Big Brother monitoring, check out TrackerPal II, which combines radiofrequency ID, the Global Positioning System and cellular phone technology to track parolees. On sale for a month, its manufacturer, SecureAlert, will lease the talking anklet with a monitoring service for $5 to $15 a day. Some 300 law enforcement agencies already use an older TrackerPal that lacks RFID.
A parolee wears the 11-ounce device on his ankle at all times. Some ex-cons are forced to stay at home, but by using GPS, police can gerrymander specific no-go zones for, say, a child molester to stay out of playgrounds. Movements are tracked at a 24-hour monitoring center that can listen in and record conversations. If a parolee wants, he can talk with an operator through the anklet. Most of the dialogue will probably be of the whoops! variety.
