Display Your Favorite Text and Images Bring your messages to life with our versatile display capabilities. With the ability to showcase up to five messages or images, our product supports three eye-catching colors—red, white, and black. Choose the color that best suits your needs, ensuring your message stands out, even from a distance or in high-attention situations. Simple Operability We designed Santek EZ Sign to be user-friendly and stress-free. Switching between displays is as easy as pressing a button on the right side of the unit. Whether you’re tech-savvy or a novice, you’ll find it incredibly easy to use right out of the box. Low Power Consumption and Long Operation Time Utilizing the low power consumption of electronic paper (E-paper), Santek EZ Sign offers long-term continuous operation without frequent charging. The built-in battery ensures that once an image is displayed, it remains visible, consuming almost no power. This means no need to worry about turning the power on and off—your messages stay displayed even when the device is off. Integrated Stand Function Santek EZ Sign features a convenient stand that can be stored flat on the back when not in use. Ideal for various settings, you can Post notices at reception desks.

Serve as a sign at entrances. Frequently Asked Questions FAQs Why does the screen flash or go blank when updating? This is normal. E-paper flashes while refreshing the display—it’s how it updates content. The 4.2" screen feels small—how big is it really? It’s measured diagonally and is slightly larger than a standard Post-it note. How long does it take to update? Around 15–20 seconds of button pressing and up to 45 seconds for image upload via app. Do I need special software? Yes. A Windows-only app is required. Download it from our Shopify support page. Can I update with Wi-Fi or Bluetooth? Not yet. Updates are done via USB (2.0 or higher) for stable uploads. Why is red showing when I only used black and white? This may occur if your image contains subtle color artifacts. Use solid black/white PNGs. Will the screen stay on without power? Yes! Once updated, the message remains visible with no power needed. Is it good for frequent updates? E-paper is best for content that changes occasionally—like menus, QR codes, or status signs. Resolution? 400x300 pixels At San Technology, Inc.

Review: Great Idea. Horrible Software/Instructions - Tried numerous versions of the software and could never get anything to load on the sign. I tried these and the 2 color and had zero luck on both despite downloading several versions and even reaching out directly to the company (with zero reply btw). That said, the signs seem high quality and the concept in general is great. They just need to include better instructions and a link/QR code to the exact software for this model.
Review: Easy setup and looks very good - Got this for my office. It is so easy to set up and the result looks very good and professional. We are just using it for wifi password display for guests, but it can be used for soooo many occasions. I am excited to find this little creative tool.

### ⭐ Terrible product impossible to read
*by J***S on August 8, 2025*

Terrible product. The letters showing g in the screen are fuzzy not clear. It reduces the font to the pont you can not read it. It only shows green screen in the background. It's impossible to read anything you write like intructions. Notices, anything you write in the screen is reduced to the pont you can not read it. There is no option to change the size of the font. It's so small that nobody can read it. Don't waste your time and money on this product suport can not help you because that is the way it was designed
