Transaction Authorisation Code (TAC)   
With effect from 5th September 2007, an online security feature known as Transaction Authorisation Code (TAC) will be introduced at AmOnline.com.my. The introduction of TAC is part of our ongoing commitment to implement best practices to protect the safety and security of AmOnline users when performing transactions via AmOnline.com.my.

In addition to Username and Password required to log into AmOnline.com.my, the TAC will provide a second level of authentication as a security check before performing specific transactions.
