- Record Necessary Information: Please ensure that you fill in all the necessary details on the fingerprinting card, including the person’s name, date, and any other relevant information required for accurate identification.
- Clean Up: Make sure to remove any extra ink from your fingers with a clean tissue or paper towel. Remember to dispose of the used materials correctly.
