Contact tracing for COVID. Sometimes it works, sometimes it doesn’t. Is there a better way?  Serial entrepreneur Richard Allen is the co-founder of Alert Trace, a wearable electronic contact tracing system. Operating via Bluetooth, the device doesn’t need GPS, meaning fewer privacy concerns and less battery power.  The system will soon be implemented by the US Navy, US Air Force, and NASA.  One-time electrician, mechanic, sound director, record store owner and accountant, Allen has done a bit of everything. He also has launched four companies onto the NASDAQ, and with his wife runs a non-profit that helps rural villages in Cambodia “create a sustainable quality of life."
