E-Ink NFC phone case

This case fits the iPhone 13 Pro Max and uses NFC link technology to project a four-colour e-ink display on the rear. No battery or Bluetooth pairing is required because the phone powers the screen during each update. The grey liquid-silicone shell adds a slim, non-slip layer with a soft microfiber lining that protects the glass back from scratches. A companion app lets you send any image from your gallery to the case whenever you want a new look.

Who this suits

The case is aimed at owners of an iPhone 13 Pro Max who want a customisable, always-visible display without carrying extra bulk or charging another device. It works only with phones that have NFC, so models lacking that feature cannot refresh the e-ink panel. Buyers who need rugged drop protection or a built-in battery should look at a different style of cover.

NFC-powered e-ink display

The defining specification is the NFC-powered four-colour e-ink screen that refreshes without cables, batteries or Bluetooth. If your phone supports NFC you can change the case artwork at any time through the dedicated app. If your phone does not have NFC the display cannot be updated, making this case unsuitable for that device.

Questions about this item

How long will the E-Ink display on this case last before it needs replacing?

The E-Ink screen is passive and draws power only when the image changes, so there is no battery to wear out and no charging port to fail.

What limits how often I can update the picture on the case during a busy day?

Each update requires an NFC tap from the phone, so the practical limit is how quickly you can launch the app, choose an image and tap the back of the phone.

Does the case get warm or make any noise when the screen refreshes repeatedly?

The display uses ambient NFC energy for each refresh, producing no heat and no audible sound during normal use.
