Working to reduce costly hospital readmissions

By linking patients, wearable biological sensors that can be read with an encrypted NFC device, and doctors or hospitals, Gentag is working to reduce costly hospital readmissions, simplify patient discharge, and enable easy in-home self-monitoring.

Discharge Kits

From the National Labs to Hospitals and Homes

Radar Responsive Tags, a sophisticated geolocation and tracking technology, are capable of precision locating items or individuals over large areas. First developed at the US National Laboratories for the Department of Defense, these tiny wireless chips are combined with sensors and capable of providing exquisite location services.
