3 Parameters

4 Instruction

Based on Bluetooth wireless communication technology, single or multiple devices can be updated with display content

(best transmission within a radius of 5 meters). The system includes electronic table cards, an app, and cloud backend

management software. The cloud platform can manage all electronic notice board devices, allowing for batch editing,

transmission of device information, and rapid deployment of conference table cards. This system is suitable for scenarios

with a larger number of electronic notice board devices.

The system can also be operated via NFC technology, which includes table card devices and a mobile app. By placing an

NFC-enabled mobile phone near the device, the content on the device can be quickly modified. All background images and

conference contents are edited on the mobile app, which is fast without the need for pairing. This system is suitable for

scenarios with a large number of desk cards that are disordered or require individual modifications.

Alternatively, a dedicated Bluetooth base station can be used to operate the devices in batches or individually via a computer

(base station transmission distance within a radius of 20 meters without obstruction).

5 Software Interface                                          

Back-end cloud-based operation for management of the list and background images. The mobile app supports data

transmit in batches, quick deployment of conference table cards highly efficiently.
