This page details all of the physical features of Passport Prime and their respective use cases.
Power Button
The physical power button on the top edge of Passport Prime has three main functions:
- When the device is completely powered off, pressing this button once will power the device back on.
- When the device is powered on, pressing and holding this button for about 1 second will show the shutdown screen. Slide the slider to the right to shut down Passport Prime.
- With the device powered on, pressing this button once will lock the device and turn off the display. Pressing it again will wake the device and prompt you for your PIN to access the device.
When the device is powered on, holding the power button for 10 seconds will perform a hard reboot.
Camera
The camera at the back of the device has multiple uses:
- Scanning transaction information from wallet software
- Verifying addresses
- Importing multisig wallet configuration files
- Importing items to the Vault, Keys and 2FA apps
Touchscreen Display
Just like all modern smartphones, this is where you will do most interactions on Passport Prime. The touchscreen supports familiar gestures including swiping down from the top of the screen to reveal the control panel, where you can toggle the Camera, NFC, Bluetooth and USB data transfer, and adjust the screen brightness with a slider.
NFC Antenna
Not visible by looking at the back of the device, the NFC Antenna sits just underneath Passport Prime's rear cover and is primarily used for creating and recovering from Master Key backups on Keycards, and for using Passport Prime as a security key. In future software releases, the NFC functionality will be expanded to cover transaction signing, wallet connections and much more.
NFC connectivity can be disabled by swiping down from the top of the screen to open the device control panel.
Bluetooth
Passport Prime uses Bluetooth Low Energy (BLE) to communicate with Envoy via QuantumLink , an end-to-end encrypted protocol with post-quantum security. This connection is used throughout the Passport Prime experience, including initial setup, firmware updates, syncing account data, and encrypted backups.
Bluetooth can be disabled by swiping down from the top of the screen to open the device control panel.
Virtual Home Button
The virtual home button with haptic feedback makes using Passport Prime as easy as using your smartphone. Tap this from within any app to return to the home screen.
USB-C Port
The USB-C port found at the bottom of Passport Prime is used for charging and data transfer. This port enables functionality within apps such as Security Keys (for logging into websites and accounts) and Files (for sharing important files to and from your phone or computer).
Passport Prime comes packaged with a USB-C cable that can be plugged into most wall adapters to charge the device battery.
USB data transfer can be disabled by swiping down from the top of the screen to open the device control panel.
Battery
You can check the current charge level of Passport Prime's battery under Settings > Settings > Battery. KeyOS 1.4.1 added several protections for the battery:
- Battery Level Critical alert - When the battery reaches 2% or lower, Passport Prime shows a full-screen Battery Level Critical alert warning that it is about to shut down. Connecting a charger dismisses the alert. If you unplug before the battery has recovered, the alert returns.
- Battery reserve - Passport Prime keeps around 15% of the battery's charge in reserve, so the displayed percentage reaches 0% before the battery is actually empty.
- Clean shutdown - Passport Prime shuts down cleanly before the battery runs flat, even if the battery percentage has drifted after many partial charges.
- Gentler charging - When fully charged, Passport Prime holds the battery at a steady 4.3V instead of cycling between 4.4V and 4.25V. This reduces long-term wear and makes the battery percentage more accurate.
