I performed a cash withdrawal in Thailand recently and noticed that the description of the transaction in my statement has changed from "IATM" to "RATM". Can you please explain the difference?

“RATM” and “IATM” are codes that we use to indicate transaction types. Transactions made at UOB ATMs in these participating countries are indicated as “RATM”. Transactions made at other overseas ATMs are marked as “IATM”.
