so does the need for security.
JCB is working hard to provide cardmembers with more security
when using JCB cards for online shopping.

JCB's Payer
Authentication Service

Secure Online Shopping with J/Secure™

Secure Online Shopping
with J/Secure™

As an international credit card brand, JCB developed the infrastructure for its new payer authentication service J/Secure™, which was fully launched in April 2004.
Compared to the currently prevailing method of payer authentication for online shopping in which the credit card number and expiration date are input, J/Secure™ excels in security. Due to the additional requirement of the cardmember's password entry, J/Secure™ can identify the user as the cardmember.
To use J/Secure™, cardmembers do not need to install any special software on their computers; the only requirement is to register their information as designated by their card issuers.

How J/Secure™ Works

  1. At a J/Secure™ compliant merchant's website, the JCB cardmember enters his/her card number and expiration date in the area for payment information. Next, the MPI* on the merchant's server delivers the information to the corresponding JCB card issuer to verify the cardmember's registration status with the J/Secure™ program.

  2. If the cardmember is enrolled in J/Secure™, a password entry screen appears on the user's PC.

  1. The JCB cardmember enters password.

  2. The card issuer identifies the password. The result is then delivered to the merchant.

  3. The merchant's system receives the result and if the passwords match, the merchant proceeds with the authorization and sales transactions following the designated procedure.
