Cardholders can enable, modify or cancel passwords by inserting cards through networked self-service devices such as touch screens and card service outlets. The cardholder does not modify the initial password, and the default is that the user has not enabled the password, and there is no need to enter the password when handling business.
Once the initial password is modified, the password will be enabled by default for this user, and you need to enter the password when using this card for business in the future.
