New, Cheaper RFID Tags?
It’s in the research stages now. Rice University in Houston and Sunchon National University in South Korea are working together to create RFID tags that can be printed directly onto the item. The key is in the ink – carbon nanotubes are mixed in. It costs about 3 cents per tag now, but they are hoping to get it down to 1 cent or less.
But . . . right now, they can only print one character in the space the size of a business card. Ultimately, they are looking at 96 bits in a 3cm area. Research continues . . .
