E-Ink NFC Phone Case

This case fits the Samsung Galaxy S23 Ultra and S24 Ultra models. It uses NFC link technology to project images onto an integrated E-Ink display without batteries or Bluetooth pairing. The four-color screen shows custom graphics set through a dedicated mobile application. A soft microfiber lining protects the handset from scratches.

DIY Personalisation Seekers

The case suits owners who want to change their phone's back appearance daily using photos or gallery images via the exclusive app. It is not for users who need a rugged shell with drop certification or a built-in power bank. Buyers wanting always-on notifications or interactive widgets should look at something else because the display only updates during an NFC tap.

Passive NFC Display

The defining specification is the battery-free E-Ink screen driven entirely by the phone's NFC field. Four-color rendering provides clearer images than basic monochrome tags while consuming zero standby power. If your workflow requires a backlit display or continuous refresh without tapping the phone, this case will not meet that need.

Questions about this item

Should I choose the S23Ultra or S24Ultra version for my phone?

Select the version that matches your exact phone model; the S23Ultra case fits the S23Ultra and the S24Ultra case fits the S24Ultra.

How does the four-colour E-Ink display work without a battery?

The screen draws power from your phone's NFC field when you update the image, so it needs no internal battery or charging.

What does the NFC link technology actually do on this case?

It transfers your chosen picture from the companion app to the case's E-Ink screen in seconds, then the image stays visible without any connection.
