In a punched card access system, the key code is specifically designed to change each time a new person checks in. This dynamic nature of the key code enhances security by ensuring that access rights are not static. Each user is assigned a unique identifier for their session or time of access, which helps to maintain an accurate record of who accessed the system and when. This is particularly important in environments where sensitive information or secured areas are involved, as it mitigates the risks associated with a static key code, such as unauthorized access or duplicity.

The intention behind changing the key code with each check-in is to ensure that access is granted only to those who are currently authorized, enhancing the overall integrity of the system. In contrast, if the key code were to remain the same for all users, be permanently programmed, or be shared among users, it would significantly compromise the security of the system by making it easier for unauthorized individuals to gain access.
