Credit card providers use 3-D Secure or 3Ds as an additional layer of security every time a Singapore cardholder uses a credit card or debit card for an online transaction. This extra authentication step protects merchants and cardholders against fraud. In other words, 3DS is a safe way to make sure that the person making the online transaction is the rightful owner of the card being used.
When a purchase is made at a merchant website that has 3DS technology, the cardholder receives a one-time password (OTP) on their mobile phone. They must then enter the OTP on the website to complete the transaction.
VISA first developed the 3DS system and offered it to consumers under the Verified by Visa service. Their goal was to improve the security of internet payments for both merchants and customers. MasterCard has since adopted the protocol under the MasterCard SecureCode, followed by JCB International as J/Secure. In 5 March 2010, the Association of Banks in Singapore adopted 3DS to further improve the security for card payments and better protect Singaporeans against fraud.
