4.1 Classify tag types.

Understand the types (active and passive) and classes of the tags. You must understand that the passive tags can operate at all frequency ranges: LF, HF, and UHF. Especially don't forget the UHF passive tags. You must also understand that tags at LF and HF often use inductive coupling, and passive tags can use backscattering.

4.2 Given a scenario, select the optimal locations for an RFID tag to be placed on an item.

You must understand that the requirement in placing a tag is that it must be easily read by a reader. Also understand that tags need to be put into different forms before they can be attached to items. You must also know that different application requirements have given rise to different forms of tags such as inserts, smart labels, and tie-on tags. Understand the issues regarding the placement of tags such as tag orientation, material of and around the tag, and selecting the adhesive to attach the tag.
