First you need some kind of colored powder or superglue to lift the fingerprint. Then you have to scan the fingerprint, invert it and print it with a resolution of 1200dpi or more onto a transparent sheet. After that, you build your fake finger by smearing pink latex milk or white wood glue into the pattern that the toner created onto the transparent sheet and wait for it to set. Finally, the CCC writes, “the thin latex sheet is lifted from the sheet, breathed on to make it a tiny bit moist and then placed onto the sensor to unlock the phone.” This method should work for virtually every fingerprint scanner on the market today.
