The foreign object detection device is especially applied in a financial self-service equipment for identifying abnormal sticking behavior or other foreign object plugging behavior, such as setting a fake keyboard on an automatic teller machine password keyboard , set a fake card slot outside the card slot, etc. The present invention forms a pattern and sprays it on the financial self-service equipment by means of a special photoreactive material. The sprayed content constitutes a hidden pattern: under visible light, the hidden pattern is transparent (invisible), and the sensitive light of the light-emitting (absorbing) material is used as an active light source , under the active light source, the background pattern and the foreground pattern appear, and the contrast between the two is remarkable. The identification of foreign object posting behavior is realized through the integrity verification of the hidden pattern. If an abnormality is found, an audible and visual alarm will be issued immediately, and the ATM monitoring center will be notified to achieve the purpose of early warning.
