1. A method for classifying a transponder and/or signals originating from a transponder, comprising the steps of:
- receiving at a reader a signal from a transponder;
determining the velocity with which the transponder is moving; and
classifying the transponder and/or signals originating from the transponder as valid or invalid in response to the determined velocity.

Abstract
The invention discloses a method for classifying a transponder (1) and/or signals originating from a transponder (1) and a reader (20) for the inventive method. According to the invention, a reader (20) receives a signal (27, 28) from the transponder (1) and determines the the velocity (v), with which the transponder (1) is moving. Finally, the transponder (1) and/or signals (28) originating from the transponder (1) are classified as valid or invalid in response to the determined velocity (v).

7. A reader, comprising:
a sender configured to generate and send first and second signals to a transponder, and a receiver configured to receive a first response signal from the transponder in response to the first signal and to receive a second response signal from the transponder in response to the second signal, wherein the reader is configured to determine the velocity of the transponder based on the time interval between receiving the first and second response signals. - View Dependent Claims (8, 9, 10)
