Abstract
A method and apparatus involve a radio frequency identification tag that receives a wireless signal containing a message type conforming to an extension of a standard communication protocol and having an extended services segment, the tag then transmitting the extended services segment through an extended services interface. According to a different aspect, a method and apparatus involve a radio frequency identification tag that stores data which includes respective information regarding each of multiple extended services, and that responds to receipt of a wireless signal which is an extension to a standard protocol by transmitting a further wireless signal which is an extension to the protocol and contains at least part of the data. According to yet another aspect, a method and apparatus involve a radio frequency identification tag that responds to receipt of one wireless signal by transmitting a further wireless signal containing information regarding multiple sensors.
