SINGAPORE - The local PayNow system that lets individuals transfer money using just a mobile number is now linked to Thailand's PromptPay version, the Monetary Authority of Singapore (MAS) and Bank of Thailand (BOT) said in a joint statement on Thursday (April 29). The linkage between the two countries' national fast payment systems is the first of its kind in the world, they said. Three of Singapore’s 12 PayNow banks are participating in the scheme - DBS Bank, OCBC Bank and UOB - together with four banks in Thailand - Bangkok Bank, Kasikorn Bank, Krung Thai Bank and Siam Commercial Bank.
