Rental housing access control device with temporary and one-time passwords

Abstract

This invention relates to a rental housing access control device with temporary and one-time passwords, used for access control management in rental properties, short-term rental apartments, bed and breakfasts, or shared accommodation spaces. The device includes a door lock body, a control module, a password generation module, a communication module, an input module, and a storage module. The control module can generate temporary or one-time passwords based on the rental period, number of uses, or validity period, and invalidate the password after use or upon expiration. This allows landlords or managers to remotely manage the access permissions of tenants, cleaning staff, or maintenance personnel without providing physical keys, reducing the risks of lost, copied, and expired keys, and improving the security and convenience of rental housing access control management.

Claims

1. A rental housing access control device with temporary and one-time passwords, comprising: a door lock body having several buttons; a control module connected to and controlling the unlocking or locking of the door lock body; a password generation module electrically connected to the control module for generating a temporary password with a validity period and a one-time password that expires after one use; an input module electrically connected to the control module for receiving passwords input by the user; a storage module electrically connected to the control module for storing the temporary password, the one-time password and their validity conditions; and a communication module electrically connected to the control module for receiving remote setting data from the administrator.

2. The rental housing access control management device with temporary and one-time passwords as described in claim 1, wherein the control module controls the door lock body to unlock when the password received by the input module meets the valid conditions in the storage module, and invalidates the corresponding password after the valid conditions expire or the one-time password is used.

3. The rental access control device with temporary and one-time passwords as described in claim 1, further comprising an alarm module electrically connected to the control module, wherein the control module activates the alarm module to generate an alarm signal when the control module determines that the password entered by the user is incorrect, the validity period has expired, the number of uses has reached the limit, or the number of consecutive incorrect entries has reached a predetermined number.

4. The rental housing access control device with temporary and one-time passwords as described in claim 1, further comprising a power module electrically connected to the door lock body, the control module, the password generation module, the communication module, the input module and the storage module, for providing the power required for operation.

5. The rental housing access control device with temporary and one-time passwords as described in claim 4, wherein the power module includes a battery, a charging circuit or a backup power supply unit, and the control module sends a low power notification or activates an alert module to generate a prompt when the power is lower than a predetermined value.

6. The rental housing access control management device with temporary and one-time passwords as described in claim 1, wherein the communication module is connected to a cloud server or an app on a manager's mobile device, enabling the manager to remotely input setting data, receive usage records, or change access control authorization.

7. The rental access control device with temporary and one-time passwords as described in claim 1, wherein the remote setting data includes at least one of the following: check-in start time, check-out deadline, permitted door opening time period, number of uses, user identification, room number, or door lock identification data.

8. The rental housing access control device with temporary and one-time passwords as described in claim 1, wherein the validity conditions include at least one of the following: password content, validity period, remaining number of uses, and door lock identification data, and the control module determines whether the password entered by the user is valid based on the validity conditions.

9. The rental housing access control device with temporary and one-time passwords as described in claim 1, wherein the password generation module generates password data based on the validity period, number of uses and door lock identification data, and the storage module stores the password data in the states of unused, used, expired or deactivated.

10. The rental housing access control device with temporary and one-time passwords as described in claim 1, wherein the storage module stores usage records, which include at least one of the following: door opening time, input result, password status, number of uses, and door lock identification data.

11. The rental access control management device with temporary and one-time passwords as described in claim 10, wherein when communication is interrupted, the control module performs offline verification based on the valid conditions stored in the storage module, and after communication is restored, the usage record is synchronized to the cloud server through the communication module.

12. A rental housing access control device with temporary and one-time passwords as described in claim 1, wherein the input module is one of physical buttons, a touch panel, or a numeric keypad.
