Bitkey uses Near Field Communication (NFC) to communicate between your phone and the Bitkey hardware device. To connect the two of them for setup, signing transactions, and general security approvals, you just need to:
- Unlock your Bitkey device with a touch from your paired finger. If you are setting up your wallet for the first time, you can use any finger.
- When prompted in the Bitkey app, bring the Bitkey device behind your phone, with the LED side gently touching the back of your phone. Different phones have their NFC antenna located in slightly different places.
For iOS, all current iPhone models have a ‘sweet spot’ near the top edge of the phone, right next to the rear facing camera. For best communication, try holding the Bitkey device behind your phone like this:
For Android devices, the location varies more from phone to phone, but is generally positioned near the centerline of the phone. When going through setup, try moving the Bitkey device slowly down the back of the phone from top to bottom until you find the positioning that works for your phone.
We’re working on improving guidance and highlighting the unique spot where your phone’s ‘sweet spot’ is in a future update!
