    Abstract: A security tag comprising at least one overt data carrier (10), and at least one covert data carrier (25), the covert data carrier comprising a ring (25) that is formed around the overt data carrier (10). The covert data carrier (25) is invisible to the unaided eye when lit with visible light, but visible when illuminated with other light, for example UV light.
