They have alcohol monitoring bracelets??

The ankle bracelet takes an air sample from the ankle at least every hour, collects that data and stores it until it can connect to a modem and go through a landline to a computer for viewing and analysis. It's taking the sweat, because 1 percent of what you drink comes out of your skin and attaches to sweat, so that's what we monitor. It's almost like a Breathalyzer on your ankle. It's a lot more sensitive than a Breathalyzer, but it's the same technology....
