InSync Software, a startup that makes an application platform for use with RFID, GPD and sensor technologies, has raised $3 million in additional financing for its technology from previous investors Intel Capital, Rustic Canyon Partners and Girish Gaitonde Living Trust. The San Jose, Calif. company is raising the money as part of a slightly larger round, according to VentureBeat sources. Insync did not respond to a request for comment. Its previous round, raised in 2006, was for $7.5 million. Insync's platform helps companies track inventory and assets for a variety of purposes. Most recently, it secured Bayer Materials as a client.
