New Scientist - RFID tags get an intelligence upgrade
New Scientist reports: "Today's RFID tags can only broadcast fixed data back to a reader device, whether that's details of your passport or of an endangered bird. Researchers are now working to add brains to the tags in the form of microcomputers, opening the way for much smarter applications."

Comment: My usual caveat applies, this is not the mark, we are just watching the tech trends. I think the future of mark tech lies in nanotech-RFID tattoos, but this report notes some interesting advances along more conventional lines.
