What is TAC?

TAC stands for Transaction Activation Code. It is a code used to verify transactions either via your mobile device in CIMB Clicks App, CIMB EVA App or through SMS to your registered mobile number in CIMB Bank’s record.


Whenever you do a transaction with CIMB Clicks, we will prompt you to request for TAC using the said channels. Once you have received the code, you will need to key it in the transaction form. The transaction will then be confirmed and acknowledged. Each TAC is unique and it is needed to ensure that the transaction is indeed being done by you.
