Fluorescent security factors in the Thai baht

The 50-baht and 1000-baht donominations of Thai baht are typically targeted for forgery. In March 2013, in the southern Nakonsi Thammarat region, a woman in her twenties was caught using a scanner to copy bills via a computer before editing them to print. In August 2010, in the northern Ubun Ratchathani region, three university students who produced 4.7 million baht of forget bills were arrested.
