SCRAMx meets the same scientific admissibility standards as blood, breath, and urine tests due to a controlled sample methodology. It is the only continuous alcohol monitoring product that provides single-source admissibility. This means it does not require a second test to confirm a drinking event.

The SCRAMx ankle bracelet is attached to the offender with a durable and tamper-proof strap. Every half hour the bracelet captures transdermal alcohol readings by sampling the insensible perspiration collected from the air above the skin. The bracelet stores the data and transmits it via a radio-frequency (RF) signal to the base station when the participant returns home.
