The guys at EM-SEC Technologies claim they’ve invented the first paint capable of keeping all those broadband-stealing cafe hobos from leeching off your wireless network. A coat of the company’s wireless-blocking paint will restrict the passage of RF signals, creating an “electromagnetic fortress” inside your home.
EM-SEC says they successfully tested the paint in their labs. Perhaps our British friends might benefit from bathing in this paint.
