Product description

• Working Principle Using NFC and electronic ink screen technology, use the APP "ink show" to edit and transmit to the back screen of the mobile phone case. Achieve quick and simple DIY long-term power-free display.Please note that the device requires IOS15 or above version
• Technology Upgrade The previous smart ink NFC mobile phone case screen only has 3 colors of pigments, black, white, and red. The pigments of our 4-color ink screen are black, white, red, and yellow, which has significantly improved the clarity and fineness of the photo display
• Good Points The reason why choose the ink screen as the display is because its display does not require continuous power supply, does not generate heat, radiation-free,and can be displayed for a long time ,wireless transmission is faster using NFC for ink screen
• Shortcomings Of course,the 4-color ink screen technology is more realistic and delicate than the traditional 3-color technology.However,we hope you can understand the shortcomings of the ink screen(Similar products that already exist or will be available in the future).The ink screen we use can display simple black and white pictures better, Obviously,it cannot compare the color,Pixel and clarity with LCD screen
• Application The snapframe e-ink phone case can display digital pictures, APP comes with pictures, text, QR codes, daily reminders and everything you want to display on the screen. The "INK SHOW" APP can freely switch the language you need in the upper right corner of the home interface. It already supports English, Spanish, Portuguese, Japanese, Arabic and Korean.
