| Summary: | The present invention provides a non-contact fingerprint identification device. A fingerprint to be tested is located on a sensing area, and the sensing area is at least 5 mm away from the non-contact fingerprint identification device. The non-contact fingerprint identification device of the present invention projects an infrared beam from at least one infrared emission module. The infrared beam is refracted to the air interface through an outer cover, and the incident angle needs to be less than 41.5 degrees. The infrared beam passes through the air to the fingerprint to be tested, and then the infrared beam is reflected by the fingerprint to be tested to a fingerprint sensor module for identification. Therefore, the fingerprint to be tested does not need to be in direct contact with the outer cover, which can reduce the effect of preventing the spread of the virus. |
