Is it legal to charge the garage with Bluetooth?

Illegal. You can make property complaints, and don't condone such arbitrary charges.

All related properties provide a Bluetooth parking card to the owner for free for the first time, and need to be replenished, lost or damaged.

In the absence of relevant legal basis and government guidance documents, it is unfounded to ask the owner to pay extra for the Bluetooth parking card without authorization, and the fee has not been approved and filed by the price department, and it is even more suspected of illegal charging.

Bluetooth card parking lot:

Bluetooth is a radio technology that supports short-distance communication between devices. It can exchange wireless information between many devices, including mobile phones, PDA, wireless headsets, notebook computers and related peripheral devices. Bluetooth card parking lot is a parking lot management system that uses Bluetooth technology to complete long-distance (within 3- 15 meters in the prior art) contactless card swiping.

The entrance and exit part is mainly composed of (host, remote card reader, vehicle detector, parking lot controller, automatic door and vehicle detection coil).

The driver puts the Bluetooth card on the windshield of the car and adjusts the angle. When the car is within 3-30m from the Bluetooth reading head, the Bluetooth card reader is activated, and the card reader reads the characteristics and related information of the card. If it is valid, it sends an instruction to the parking lot controller, and the parking lot controller sends a switch signal to the gate, and the gate rises. After the vehicle sensor detects that the car passes by, the railing automatically falls. If the card is invalid or expired, the gate will not be raised. When the vehicle is under the induction coil, the automatic brake lever will never fall. The vehicle sensor has the function of preventing the vehicle from being hit.

Management Center: Administrators can authorize remote cards on the management software, and only authorized cards can be used. Administrators can also manage remote cards on the master controller.
