RFID today and tomorrow

Many of us already use RFID tags routinely. Examples include:

Some fifty million house pets around the world have RFID tags implanted in their bodies, to facilitate return to their owners should they become lost. In a world where everyday objects carried RFID tags –perhaps the world of the future – remarkable things wouldbe possible. Here are a few possibilities (among the myriad that the reader might dream up):

  1. Smart appliances: By exploiting RFID tags in garments and packages of food, home appliances could operate more cleverly. Washing machines might select wash cycles automatically, for instance, to avoid damage to delicate fabrics. Your refrigerator might warn you when the milk has expired or you have only one remaining carton of yogurt – and could even transmit a shopping list automatically to a home delivery service.
  2. Shopping: In retail shops, consumers could check outby rolling shopping carts past point-of-sale terminals. These terminals would automatically tally the items, compute the total cost, and perhaps even charge the consumers’ RFID-enabled payment devices and transmit receipts to their mobile phones. Consumers could return items without receipts. RFID tags would act as indices into database payment records, and help retailers track the pedigrees of defective or contaminated items.
  3. Interactive objects: Consumers could interact with RFID-tagged objects through their mobile phones. (Some mobile phones already have RFID readers.) A consumer could scan a movie poster to display show times on herphone. She could obtain manufacturer information on a piece of furniture she likes by waving her phone over it.
  4. Medication compliance: Research at Intel and the University of Washington exploits RFID to facilitate medication compliance and home navigation for the elderly and cognitively impaired. As researchers have demonstrated, for example, an RFID-enabled medicine cabinet could help verify that medications are taken in a timely fashion. More generally, RFID promises to bring tremendous benefits to hospitals
