Abstract
The fingerprinting system includes a main body, an air movement source, an ignitor, and a hydrocarbon fuel source. The main body includes a handle. The air movement source includes a fan. The air movement source is coupled to the main body. The fingerprinting system is configured to burn the hydrocarbon fuel source to produce soot containing carbon. The air movement source is configured to direct the soot containing carbon toward a surface to be analyzed for fingerprints.
