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.
Abstract translation: 包括至少一个公开数据载体(10)和至少一个隐蔽数据载体(25)的安全标签,所述隐蔽数据载体包括围绕所述公开数据载体(10)形成的环(25)。 隐藏的数据载体(25)在用可见光照射时对肉眼是不可见的,但是当用其它光照射时可见,例如UV光。
