C|Net's Alorie Gilbert once again lays out the case for RFID in this article. A very positive leaning overview, with not much new, but there are some projections as to timing and size of market that some may find interesting.
Gilbert lays out some technical hurdles to overcome, but they don't sound like major obstacles. On the social side, Gilbert has this to say:
Beyond the technical issues, the technology faces difficult political obstacles in the form of organized labor. Unions don't want to see warehouse and shipment workers' livelihoods automated away by computers, as evidenced last year when a strike by dockworkers over the introduction of new technology brought commerce to a halt on the West Coast.
Other concerns are being raised by privacy advocates, who fear that the use of RFID chips in consumer goods will eventually lead to a surveillance society. Initial trials by Wal-Mart and Britain's largest retailer, Tesco, to tag individual products with RFID devices were met with boycotts and protests.
