BANGKOK, Aug. 30 -- Travelling in Thailand this November? Don't be alarmed if your 50- and 100-baht notes look a little different; they're going polymer.

Thailand began switching banknotes to plastic in 2022 with the 20-baht note, which lasts about eight years - four times longer than paper.

Bank of Thailand Governor Sethaput Suthiwartnarueput said the new polymer bills resist dirt and moisture, so they're tougher and longer-lasting, Bangkok Post reported yesterday.

That means fewer replacements are needed, saving money and cutting waste; a win for both the bank and the environment.

The notes will look familiar, but watch for upgraded security features like a transparent window with embossed numerals and colour-changing ink.
