With the advancement in technology, forgers further improve their methods to create more accurate forgeries. Although various techniques have been used to detect forged banknotes, the use of microwave spectrum in detecting forged banknotes is a relatively new research area. In this study, we investigated the application of microwave energy in detecting forgeries on banknotes. The proposed method was based on the thermoelastic optical indicator microscopy technique, which visualized the distribution of microwave near-fields. The Korean banknotes of 1000 won, 5000 won, and 10,000 won, and their corresponding scanned samples were selected, and the distribution of microwave near-field was measured. Our results showed a strong distribution of the microwave magnetic near-field on the hologram at 12 GHz for 5000 won and 10,000 won, and the field distribution of the corresponding scans was different. On the other hand, the microwave near-field distribution of the 1000 won and its scan showed a similar distribution.
