GO Secure Payment is a system developed by BKM that verifies cardholders using a one-time password (OTP) during online purchases made with TROY cards. It provides a secure verification platform for the banks included in the system.
Because the GO system does not need to store card data and can query card data in real time, cards do not need to be registered in the system beforehand; card verification is left to the issuer bank. In 3D Secure systems, card information is updated in the BKM system only after a certain delay, whereas the GO system has no such waiting period.
The Difference Between GO and 3D Secure
Both systems verify the cardholder's identity with a one-time password during online purchases. The key difference lies in where the card information is kept. As noted above, the GO system does not require the card to be registered in the system in advance. Verification is checked with the issuing bank at the moment of the transaction. This means newly issued cards or cards with updated information can be used without any waiting period.
How Does It Work for the Cardholder?
- The cardholder enters their card details on the website.
- If the card is a TROY-branded card, the cardholder is redirected to the GO system for verification.
- A one-time password is sent to the phone number registered with the cardholder's bank.
- Once the password is entered correctly, the transaction is forwarded to the bank for authorization.
From the Merchant's Perspective
Transactions verified through GO, just like transactions verified through 3D Secure, give the merchant assurance that the cardholder has been authenticated. This protects the merchant against cardholder disputes claiming "I did not make this transaction."
Current Status
Card scheme verification systems have since moved on to newer versions such as EMV 3-D Secure. For the current scope and use of the GO system, BKM's latest announcements should be followed.
