A fingerprint scanner views an image of the small ridges in your fingers to recognize the initial pattern that's yours alone. You may make an electronic camera right into a "thumb scanner" which will save yourself an image of the fingerprint taken. The process depends on the macro setting of the camera -- selected from the menu settings -- which enables the lens to concentrate excessively close-up to an object. The camera won't be damaged by any means from it as a thumb scanner.
Open the battery compartment lid of the camera and insert new batteries. Close the lid. Open the memory slot quietly of the camera and insert a compatible memory to the slot. Close the lid. If the battery compartment also offers an area for the memory, skip this split up step. Press the digital camera's "On" button. Press the "Menu" button that's an average of on the right back of the camera alongside the LCD viewing panel. Choose the "Lens" menu or perhaps a comparable menu -- the particular name will be different with respect to the model of the camera. Choose the "Macro" setting. Press the "Menu" button again to exit the settings. Press the "Flash" button, or press the tab alongside a flash icon to temporarily discontinue the utilization of the automatic flash feature. In some instances, activating the macro feature will automatically turn this off. Place the camera on a dining table with the lens facing up. Place among your thumbs while watching lens, several inches away. Press the shutter button on the camera halfway right down to lock the focus of the thumb -- an average of a "beep" will undoubtedly be heard to point that the focus has become locked. Press the shutter button all of those other way right down to have a picture. Stand the camera up following the picture has been taken. Press the "Menu" button. Choose the "Playback" feature and on the LCD screen you can observe the picture which was just taken. Choose the thumb picture from all of those other thumbnail images displayed on the LCD screen. View the picture of the thumb to verify that it's in focus -- if the thumb isn't in focus, try taking yet another picture, moving the thumb closer or farther away than before. The thumb scan that the camera "thumb scanner" has had are now able to be used in some type of computer via the memory and viewed on a bigger monitor screen or combined with any security scanning program that you may have.
