Card Storage:
The terminal is capable of storing information for up to 3000 access control cards. This means it can manage a large database of users who are authorized to access a specific area or resource.

Access Control Function:
This implies that the terminal is designed to control access to a particular space or resource. It can determine who is allowed entry based on the information stored in its database.

Authentication Methods:
The terminal supports multiple authentication methods, specifically card and password. This means users can gain access either by presenting their access control card or by entering a predefined password.

Data Persistence:
Even when the device is powered off, the data it has stored remains intact. This is crucial for maintaining the integrity of the access control system, ensuring that user information and access privileges are not lost due to power outages or device shutdowns.
