A pilot study with the aim of identifying the palm prints on thermal paper parking tickets

This article presents the results of an experimental study to identify traces of human hands on thermal paper. Coupons from paid car Parking lots are used as objects. Identification of these traces was carried out by heating the thermal paper. In the course of the study, the temperature range is established, in which the traces of human fingers are detected with the greatest clarity, and the identification features are expressed most qualitatively. Thus, the detection of these traces on thermal paper is possible using the thermal method.
