Abstract: A composite lock includes a lock control unit and a Bluetooth unit. The Bluetooth unit is connected to the lock control unit, and the Bluetooth unit controls the lock control unit according to a result of pairing and authentication with a handheld unit, so as to enable the composite lock to be in a locking state or an unlocking state.

Abstract: A storage device includes an access control module and a Bluetooth transmission module. The storage device can control a data access right through a mobile device performing authentication. After receiving a start signal, the Bluetooth transmission module searches for a mobile device, and permits access to the access control module according to a Bluetooth position and pairing data.

Abstract: A non-contact control method and a non-contact control device are applied to a lock control device in a non-contact mode for manipulation. The non-contact control device includes a master control module and a slave control module. Both the master control module and the slave control module include a radio frequency identify (RFID) component and a Bluetooth component. In the master control module and the slave control module, the RFID component serves as first-layer authentication and unlocking and starts the Bluetooth component, and the Bluetooth component serves as second-layer authentication and unlocking and triggers a circuit control device. The master control module actively starts the slave control module and performs pairing and unlocking, so as to achieve a non-contact locking and control mode with low energy consumption and high security.
