How does the room card set the time?

Set the time for this card as follows:

1. The manufacturer preset the programmable alarm clock function in the chip embedded in the room card. This function can be set to take effect at a specified time, or it can be triggered periodically as needed.

2. After the room card is issued to the user, the user can set the card time in the corresponding card management system through a special card reader or computer software.

3. The user sets the start and end time as needed and inputs it into the management system. The management system will transmit these time data to the chip in the card.

After the setting is completed, the chip in the room card will be controlled according to the preset time parameters. During the effective time, users can use the room card to open related facilities, such as hotel rooms and access control. Once the set time is up, the room card will not be used.
