Protecting your transactions on Personal Internet Banking and UOB TMRW

For improved security to protect your exposure to any possible scams, we had revised the funds transfer limits with effect from 30 July 2022. This applies to fund transfers to other UOB accounts, other bank accounts, eNETS, Telegraphic Transfer and PromptPay.
