摘要：A reader for a secure tag. The reader comprises a first excitation source (such asone or more LEDs) that stimulates at least one transition in the secure tag. The readeralso comprises a second excitation source that stimulates more transitions than werestimulated by the first excitation source. The reader has a detector for detecting

luminescence from the secure tag in response to excitation from the first excitationsource and in response to excitation from the second excitation source to ensure thatluminescence is detected at a pre-determined wavelength in response to the secondexcitation source but not the first excitation source.
