First-time setup
Check that your ERA is genuine
On a new device this check runs once, right after the welcome screen. The device and the app exchange two QR codes: the app asks a question, the secure chip inside the ERA signs the answer, and the app verifies the signature.
Steps
Part 1: Install the app
On WELCOME TO ERA WALLET, tap START.

ERA: Welcome. On COMPANION APP, tap IOS or ANDROID to match your phone.

ERA: Companion app, choose platform. Point your phone camera at the QR code on the ERA screen. The app's store page opens on the phone.

Trouble?
The ERA shows INVALID REQUEST → the code was not an authenticity request. Tap REPEAT, open Authenticity Check in the app again and rescan.
The camera does not open and the device asks you to disconnect the charging pad → take the ERA off the pad; the camera is disabled while charging.
The ERA does not read the phone screen → raise the phone brightness, hold the phone 15–20 cm from the camera and keep it still.
The phone does not read the ERA screen → tap the ERA screen to switch on its front light, and add room light. Source: Help Center
The app says the device is not genuine → run the check again. If it fails two or three times in a row, do not enter a PIN or create a wallet; contact ERA support (support@hwlt.io or Telegram @ERAwlt_support_bot) with the serial number shown in the app. Source: era-wallet.com, Help Center
