E-Paper ID Badge: Joan Shrinks Signage to Four Inches

Joan’s four-inch color e-paper badge combines employee identification, visitor management and access control, and is managed through the Joan Workplace platform in more than 90 countries.
Joan has introduced a wearable four-inch color e-paper badge that combines employee identification, visitor management, and access control in a single wireless device, according to the company. The badge is managed through the same Joan Workplace platform that powers the company’s room-booking and desk-booking solutions, and is available in more than 90 countries.
The four-color ePaper display updates via Bluetooth, requires no wiring, and delivers up to 200 days of battery life with two updates per day. The badge is attached to a person rather than a place, extending the company’s display workflows to a mobile surface carried throughout a building. Connectivity is Bluetooth and NFC (NXP MIFARE DESFire EV3).
The launch reflects Joan’s strategic shift away from standalone hardware toward its Joan Workplace platform, which combines room booking, desk booking, visitor management, and digital signage within a single cloud-managed environment. Employee data, calendars, visitor information, user directories, and access-control systems already power Joan’s displays; the wearable extends those workflows to a badge. Joan also acknowledges the technology’s limitations: ePaper is not intended for video, dashboards, or dynamic content, with LCD and LED remaining the better choice for those applications. ePaper excels where content changes infrequently, deployments scale into the hundreds, and cabling is impractical.
The Joan e-paper badge supports three primary use cases: employee ID, visitor badge, and event credential. Assigned through the user directory, badges automatically synchronize names, photos, and job titles; integrated NFC based on NXP Mifare Desfire EV3 supports door access where compatible infrastructure is available, and lost badges can be revoked instantly. For visitors, information is written wirelessly to a nearby badge on check-in; after the visit, the badge is returned to a charging dock, cleared, and reused, eliminating disposable labels and reducing printer usage. Event organizers can provision hundreds of badges directly from attendee databases, with last-minute changes requiring only a re-sync rather than a reprint, while badges can be collected and reused after the event.
