The paper money was first used in Thailand in 1902 according to the Siamese Currency Notes Act, Ratanakosin Era 121 under the supervision of The Royal Treasury Department (presently the Ministry of Finance). The Bank of Thailand was established according to the Bank of Thailand Act B.E. 2485 for the purpose of taking over the management of the note issue from the Ministry of Finance and of carrying on such business as pertain to central banking in accordance with the provisions of the Act and the Royal Decreed issued. For this reason, the authority and duties associated with banknotes were wholly transferred from the Ministry of Finance to the Bank of Thailand.

Always check your banknotes to deter counterfeiting.

Banknotes are legal tender by law. Therefore, in order to maintain their reliability as medium of exchange, "banknotes" are to be produced with particularly anti - counterfeit features.

The important responsibility of the Bank of Thailand (BOT) is to design, print, issue, and manage banknotes to ensure that banknotes in circulation are sufficient as means of payment for the economy. The Banknote Management Group was thus set up to be directly responsible for printing and issuing of Thai banknotes.

Upon relocation to the new site, the Banknote Management Group remains committed to maintaining and updating those certifications, and extends the coverage to the functions of the Banknote Issue Department and the Banknote Strategic Planning and Administration Department.
