Corsedia is an access control app.

○ QR code pass issuance function

Corsedia is issued a QR code pass valid for a certain period of time by submitting data through self-examination before entering and exiting, and through it, data on who entered the building, when and how, can be managed.

○ Traffic tracking system

Existing GPS technology makes it difficult to track movements inside buildings with many floors due to the limitations of satellite reception.

Corsedia uses BLE (beacon) technology to configure its own GPS where it is needed, enabling effective tracking and identification of traffic lines even inside buildings with many floors.
