QR Readers & Terminals
Display QR and card terminal
QR codes, cards and a 3.33-inch touch screen in one compact terminal. Choose a reader or access-control configuration and use DejaOS to shape the on-device experience.
Inside FC6820
FC6820 brings QR and card interaction together with a touch display. At an entrance, the application can guide the user and show the result of a credential check. At an attended desk, a separately selected stand can place that interaction within reach. Choose the device role before planning the software and door wiring.
Plan the installation
Choose around your project
Use the reader version to pass credential data to a host or controller. The access-control configuration adds exit-switch and door-contact inputs and relay output. Do not assume those door connections are present on every version.
Plan the instructions, credential prompt and result message around your application. DejaOS provides a development path for a custom interface; confirm the SDK and firmware for the supplied configuration. Wi-Fi and voice are options.
For a wall installation, review the 86-box mounting and cable route. For a desktop interaction, confirm the stand and rear clearance separately. The mounting arrangement should keep both the screen and reading area accessible.
From credential to action
Ethernet and RS485 describe connections, not universal compatibility. Match the data format, response handling and firmware to your host. Confirm behaviour when the network is unavailable before deployment.
The user scans a code or presents a supported card, with the display guiding the interaction defined by the application.
The selected application, server or compatible controller checks the credential. A successful read alone does not grant access.
The application presents the result. Door operation uses either the matched external controller or the selected access-control configuration and its approved circuit.

The source filename says READER, while its diagrams include access-control connections. Use it only after matching the exact terminal version and harness.
No. Select the reader or access-control configuration first. Exit-switch and door-contact inputs and relay output apply to the access-control configuration. Match the supplied harness and firmware to the connection reference; a shared model family does not make every version interchangeable.
Do not assume so. Reader firmware and access-control firmware can use different tools, configuration codes or platform commands. Share the overseas model, firmware and intended operating mode so the matching method can be checked before changing settings.
No. A device can have local network access without maintaining its platform or messaging connection. Check the physical network, IP settings and service connection separately, using the indicators or logs available for the selected system.
