German luggage maker Rimowa has added e-ink displays to their latest line of luggage, allowing airline apps to transmit the correct details to your luggage via bluetooth. A dedicated drop-off area lets you skip the line and priority handling/VIP status can even be transmitted.
Two regular AAA batteries are good for around 500 tag changes and according to Engadget the e-ink display only requires power to add a new tag, so the existing tag will be fine even if the battery dies in transit. The display is made of Gorilla glass and Rimowa claims that the tag is less likely to be damaged than a normal paper tag.
Lufthansa is currently supporting the tags while United is testing them. Check out Rimowa’s website for a full interactive demonstration.
