RFID is pretty neat. I designed a cow thermometer (for veterinarians) that
logs the cow ID (read from an RFID tag), the cow's temperature, the date
and time. Thousands of readings can then be downloaded later for analysis
and archive. Prior to this, the typical logging system consisted of
writing the date and temperature in chalk on the side of the cow...
