Wi-Fi Password Display for Cafés & Small Businesses

Are you a coffee shop, restaurant, or coworking space owner looking for a simple and affordable way to protect your Wi-Fi network from non-customers and previous visitors?

Still using handwritten chalkboards or paper signs to display your Wi-Fi password? Replace them with this simple digital Wi-Fi password display!

Using it is very simple: press a button to generate a random password, manually update your router with it, and once the router is updated, the generated password becomes your new Wi-Fi password and is clearly displayed for your customers.

The entire process takes less than one minute and only needs to be done every few days.

This device is a simple, low-cost solution designed for cafés, restaurants, coworking spaces, waiting rooms, and other public businesses.

Installation Notes

To mount the enclosure properly:

• Align the lower edge of the wall-mounting piece with the lower edge of the enclosure.
• Align the left and right sides.
• Slide the enclosure slightly downward to secure it.

The PCB holes will align automatically with the wall-mount features.

Please refer to the final photo and video for guidance.

SSID Label

For the small paper label glued to the enclosure to display the Wi-Fi network name, there is an 50 × 10 mm rounded rectangle on the enclosure designed for this purpose. I have also prepared a Word document that contains two rectangles—one black and one white. Simply write your Wi-Fi network name in the document, print it, cut out the label, and glue it onto the enclosure.

This is the Word document—just click to download it.

PCB Only Option
