Answer Details
Counting of currency notes with moist fingers is based on the principle of adhesion. Adhesion is the tendency of dissimilar particles or surfaces to cling to one another. When currency notes are moistened, the water molecules adhere to the surface of the paper and increase the friction between the notes, making them easier to separate and count. The same principle is used when licking the tip of a finger to turn the pages of a book. The moisture adheres to the page, allowing for better grip and separation.
