Abstract
A smart tag reading system is provided that has the ability to query sensor tags that have energy harvesting capability. In one embodiment, an adaptive reader system learns the state of each tag and how long the tag takes to charge. Tags that charge relatively quickly can be accessed more frequently. Others that do not charge as quickly, readings can be performed at much longer intervals allowing the tag a longer time to gather enough energy to complete the transaction. The reader query system can then adapt to the environment and state of the individual tags.
