Batteryless e-paper ID

The ID card that writes itself.

Batteryless e-paper ID cards, issued with a tap. No battery, no charging, nothing to maintain — the display holds its image with zero power, so the card always shows the holder’s details.

Tap the card to reissue it

How it works

Issued in seconds, not weeks.

No print queue, no reprint cycle when a name or photo changes. The holder does it themselves, in three steps.

01

Register online

The holder signs up and their details are approved on the platform — before a card ever exists.

02

Collect a blank card

Any blank card from the stack. There is nothing on it yet, so there is nothing to get wrong.

03

Tap. It becomes yours.

One tap with their phone and the card writes itself — name, photo, credentials, done.

Nothing to charge, ever

The tap itself powers the update.

The card draws all its power from the phone or reader that touches it. That brief tap is enough to rewrite the e-paper display — and once written, the image holds itself there with zero power. A card can sit in a drawer for a year and still show the holder’s details, sharp as the day it was written.

Reusable by design

One card, many holders.

BEFORE PRINT USE DISCARD PRINT AGAIN
WITH INK ISSUE USE WIPE REISSUE

When someone leaves, their card is wiped and reissued to the next person. The whole print–reprint–discard cycle disappears — less printing, less waste, and a stack of blanks that never goes out of date.

Secure by design

A card nobody else can rewrite.

[SIGNED]

Every write is approved by the platform and verified on the card — a generic NFC app can’t change a thing.

[ONCE]

Self-issue works exactly once. A card claims its holder on the first tap, then locks to them.

[REVOKE]

Lost cards are revoked instantly from the platform — no chasing, no waiting for a reprint.

Two products, one platform

Ink is one half of the story.
