Frequently asked questions
Everything we get asked, in one place. If your question isn't here, get in touch.
The product
How does it work without a battery?
Your phone's NFC radio puts out a short-range electromagnetic field. A small antenna inside the Cherikey harvests that field for the few seconds it takes to redraw the screen, then the device goes completely dead. E-ink holds its last image with no power at all, so the photo stays put.
What size is the screen?
The screen is 1.5 inches.
Can I add text?
Yes — a caption line under the photo. A name, a date, a few words. It's drawn in the same e-ink.
Is it waterproof?
Splash-proof. Rain, a spilled drink and a wet pocket are fine. It is not rated for submersion, so leave it out of the pool.
How many times can I change the picture?
There is no practical limit. E-ink is rated for well over a million refreshes, and there's no battery to wear out.
The app
Do I need an account?
No. There is no sign-up, no subscription and no cloud. The photo goes from your phone straight to the keychain.
Can someone else change my photo?
Only if they physically hold the keychain against their own phone with the app open.
Can one phone manage several keychains?
Yes, as many as you like. The app keeps a list so you can see what's on each one.

Yes. We offer worldwide shipping on all orders.
How long does delivery take?

How do I track my order?

What if my order is delayed?

The screen shows a faint ghost of the old image. Is it broken?
No — that's normal e-ink behaviour after many partial refreshes. Send the photo again and the app will run a full refresh cycle, which clears it.
