In this paper, we present an application of RFIDs for supply- chain management. In our application, we consider two types of readers. On one part, we have readers that will mark tags at given points. After that, these tags can be checked by another type of readers to tell whether a tag has followed the correct path in the chain. We formalize this notion and define adequate adversaries. Morever, we derive requirements in or- der to meet security against counterfeiting, cloning and impersonation attacks.
