The Yankee Group estimates that manufacturers will spend about $2 billion on radio frequency identification (RFID) tags and another $1 billion to $3 billion on infrastructure over the next three years. The largest portion of the infrastructure spending will be allocated to consultants and system integrators, the firm said. The growth of RFID will impact about 4 million jobs by 2007, as some jobs will be lost while others will transition from “the mundane to value-added positions,” the firm added.
