The following is a guide on how to track each item with RFID. Each item is linked to it's own page with more tagging information.
The most important aspect is the type of material being tagged, so we broke it into raw material types. A secondary aspect is the type of item. For instance, an automobile will be traveling vast distances and should probably be tagged with a GPS/Cellular based RFID tag.
Raw Material - This is the basic material being tagged.
Typically Found In -- Where this material is primarily found.
RF Penetration -- % of RF signal that passes through this material. This means the the item can be used as a container if it's near 100%.
Each raw material and item has it's own web page devoted to tagging it and the issues associated with that item.
