How does the property directly invalidate the water drop access card?

The practice that the property directly invalidates the water drop access card is usually realized through the following steps:

1. Reading access card information: The hotel uses a special access control system to identify the identity and authority of the access card by reading the information in the access card.

2. Disable the access card: When the property needs to disable the access card, the system will record the information of the card and mark it as disabled. This means that when the cardholder tries to open the door with this card, the access control system will not respond.

3. Update the access control system: In order to invalidate the access control card, the property may need to update the access control system to ensure that all access control equipment is synchronized with the latest system.

It should be noted that the specific operation steps may be different for different access control management systems. In addition, the operation of invalid access cards usually requires specific permissions and access levels, so only specific personnel can perform the operation.
