Multiple currency numbers

I recently had to transfer some money into Thailand. I was given an invoice with a bank account number on it.

I wanted to complete payment in USD and they said I can send USD or any currency to that same number. I was suprised because I thought that number would only recieve baht. I'd never encountered this account/product. When I need to send or recieve a certain currency I need to provide the individual account number for each currency.

How new and wide spread is this technology?
