Picase is a protective phone case with a built-in e-ink display on the back. E-ink is bistable: once an image is written, it stays visible without using power until you change it again.

Your iPhone provides short, momentary energy through NFC at 13.56 MHz. The case’s internal antenna harvests that energy, the electronics convert and regulate it, and then run the e-ink update sequence. When the update finishes, everything goes passive and the image remains because the pigments physically hold their position.

No, NFC is only active for the transfer window, which lasts a few seconds. Keeping an image displayed consumes zero power. You will not see any battery impact.

Unlimited. There is no change counter or cycle limit for typical use.

No. Changing your photo is completely offline. Tapping the case launches the experience locally, the image is processed on-device, and the handoff happens over NFC without Wi-Fi or Bluetooth. It even works in Airplane Mode.

High-contrast photos, clean backgrounds, and bold, clear type produce the sharpest results.

Here can be a brief but clear response to the question, giving customers a quick answer without unnecessary details.

No. NFC is used briefly during the image update and does not interfere with payments or radios. Everyday connectivity works as normal.

The case includes an internal magnet ring that lets MagSafe chargers snap into place and stay aligned, so you get the charging your iPhone supports without removing the case.
