4.3.2Command Description

Before using the PINPAD, you must set the UID in a secure environment. Without the UID,
all the sensitive services cannot be accessed. When a UID has been set, it cannot be changed.
In the process of sensitive services' authentication, UID will be involved in the calculation of
Authentication Code, and it will be used in both direction's authentication between the
sending host and the PED, therefore attack by replacing the PED cannot be successful.
