日本最近开发出一种包含光源和摄像元件的“把手型手指静脉”认证仪器。把它嵌入汽车车门的把手中后,车主不用钥匙也能开、关车门。该仪器的光源嵌在门的把手上,摄像元件则嵌入车门。当汽车主人的手握住把手时,仪器就可获得他指背静脉的清晰图像。这图像与电脑中存储的图像一比对,如果完全一致,车门就会打开。 Japan recently developed a “handle type finger vein ” authentication device that includes a light source and an image pickup device. After it is embedded in the handle of the car door, the owner can open and close the car without the key. The light source of the instrument is embedded in the handle of the door, and the imaging element is embedded in the door. When the car owner’s hand holds the handle, the instrument can obtain a clear picture of his dorsal vein. The image is compared with the image stored on the computer, and if it is exactly the same, the door opens.
