RF-Only Logic Makes RFID Tags Tinier

Engineers at North Carolina State University have applied a new technology called RF-only logic to create passive RFID tags that are 25 percent smaller than today’s. And a smaller tag means a cheaper tag. The space savings comes from eliminating a circuit usually considered crucial to the chip’s operation—the rectifier. Passive RFID tags, the most…

Disney Made Use OF RFID Tags to Transform Ordinary Toys

Scientists at Carnegie Mellon University, Disney Research, and MIT have recently come up with new uses for off-the-shelf radio-frequency identification (RFID) tags. They are able to develop a new technique and system for processing these RFID tags for practical applications in games, interactive objects and toys, and physical interfaces. The ‘RapID’ system the researchers developed…
