The RF absorption is dependent on the contents of the pallet. Cardboard, plastic, and wood have low absorption and can be easily tagged. Glass and liquids cause slightly higher problems but tag placement can be easily adjusted to accommodate them. Metal pallets or pallets containing metal objects need to take into consideration the tag placement and possibly use a metal-mount RFID tag if appropriate.

Common placement of RFID tags on pallets is on a shrink wrapped area of the pallet. If you are tagging the contents of the pallet with carton-level tags and using pallet-level tags for the pallet, be sure not to apply a pallet-level tag directly to any of the items on the pallet. Shippers may often decide to place the tag on the pallet itself and re-use that same pallet ID for multiple shipments. The best placement for a re-usable pallet ID would be behind a wood beam on the pallet, or molded into the base of a plastic pallet. 

The best tag to use for pallet tagging is the NOX-1 4"x3/4" RFID tag. The NOX-1 includes a 4"x1" peel-off traveler label that can be placed on a document for record keeping.
