…the most important groups are manual laborers—whose fingerprints tend to wear off from excessive use of their hands—and children, whose fingerprints are not fully developed or undergo changes with development; as well as the disabled or amputees. These challenging cases require adopting exception-handling protocols (which may be relevant for 1 to 2 percent of the population) in order to ensure total inclusion.
