In the 2000 movie Memento, the main character tries to solve the mystery of his wife¿s murder, despite suffering from amnesia that causes his brain to effectively "reboot" every 5 minutes. In the world of computing, "passive" radio-frequency identification (RFID) chips have a similar problem. Dependent for power on infrequent, scavenged RF energy from a reading device, RFID chips may reboot more than once per second and then lie dormant indefinitely, waiting for the next reader to come along.
