1. A method for detecting an invalid Radio Frequency Identification (RFID) tag comprising the steps of:
- reading at least part of an identifier and authentication information from a given RFID tag;
verifying said authentication information dependent on at least a given part of said identifier; and
determining that said given RFID tag is an invalid RFID tag based on said verifying.

Abstract
For detecting an invalid RFID tag, an identifier and authentication information is read from a given RFID tag. The authentication information is then verified dependent on at least a given part (IDP_TAG) of the identifier (ID_TAG) and it is determined that the given RFID tag is the invalid RFID tag if the verification was negative. Accordingly, an RFID tag is manufactured by determining an identifier (ID), determining an authentication information dependent on at least a given part (IDP) of the identifier (ID) and storing the identifier (ID) and the authentication information on or in the RFID tag.
