What is KEEP?
A bamboo keychain with a small e-ink screen. It displays a note from someone you love, and that note goes everywhere with you: in your pocket, on your keys or on your bag.
How does it work?
- A loved one writes from the app, free on iPhone and Android. They can send a text, a drawing or a sticker, from anywhere in the world.
- You get a notification on your phone.
- You hold your phone against KEEP for about 2 seconds. The note travels over NFC (just like a contactless payment) and appears on the screen.
- The note stays on display until the next one arrives.
Several people can write to the same KEEP, as long as the owner invites them.
Specs
- Screen: 2.13-inch (about 5.4 cm) black-and-white e-ink display. It uses no power as long as the note doesn’t change.
- No battery, nothing to charge: KEEP draws power from your phone during the 2-second update.
- No Wi-Fi, no Bluetooth: NFC only. The only thing that needs internet is sending the note, from the app.
- Material: natural FSC-certified bamboo, hand-finished.
- Moisture- and scratch-resistant.
- KEEP displays text, drawings, stickers and black-and-white photos.
Compatibility
You need a phone with NFC: iPhone 7 or newer, or most Android phones released after 2015.
Some entry-level Android phones don’t have NFC. You can check under Settings > Connected devices > NFC.
