The RFID market in health care has been going through some significant changes, many of which were evident at HIMSS 2007. The latest evidence of evolving business models is the merger announced today between InnerWireless and PanGo (press release).

While styled as a merger, PanGo will be absorbed by InnerWireless with only half of PanGo's 30 employees remaining in their Massachusetts engineering facility. PanGo co-founder Micheal Campbell will serve as InnerWireless' Senior VP for location services, and is the only PanGo exec mentioned as staying with the combined firm. PanGo's investors got just one seat on InnerWireless' 8 member board of directors. Ed Cantwell remains InnerWireless president, CEO and chaiman.
