    Credit/Debit Card Security And You


At UOB, credit/debit card security and customer confidentially are of paramount importance. As a leading regional bank, we are committed to adopting the best security practices to serve you better. To do this, we have implemented additional security safeguards that include the 3-D Secure (3DS) and SMS alerts service so as to provide you with greater peace of mind.


You will receive an SMS for the following transactions:

First transactions made with a new or renewed credit/debit card


High-value transactions
(above the threshold limit+)


One-time password for internet purchases authentication at participating online 3DS merchants.

What is 3-D Secure

3-D Secure (3DS) protocol is used by banks worldwide to authenticate online card transactions. Cardmembers will recognize the participating 3DS online merchants by Visa's Verified-by-Visa, MasterCard's SecureCode or JCB's J/Secure logos. 3DS will be made applicable to American Express Cards by 31 March 2011.

When making purchases online, 3DS will prompt Cardmembers to enter a One-Time-Password (OTP) to authenticate the transactions. If the OTP is correct, the purchases transaction will be processed and completed.
