You would be shocked to know the alarming rate at which online frauds have increased in the past few quarters. There are methods in place such as 3-D Secure by different card companies. However, hackers continue to find their way around it due to different reasons. Typically, 3-D Secure protocols prompt the user to enter either a password or an OTP that they send for authorizing a transaction.
Checking if the user is a part of the 3-D Secure program.
When users first sign up, they have to either enter a password or select to receive an OTP, which will be used for authorizing a transaction. A Merchant plug-in, or MPI, is used for facilitating authentication and identifying the account number for checking if the user is a part of the 3-D Secure program or not.
Some users abstain from registering from 3D Secure as they think that it is a hassle more than a security feature. But with the new technologies in places such as Access Control Servers or ACS, there can be more security incorporated in the transactions.
