Change: Retry 19-digit ICCID login with a Luhn check digit
Why
Some IoT cards are entered or scanned as a 19-digit ICCID prefix. The asset-verification endpoint requires the 20-digit ICCID, so the first verification cannot return an asset token even though the identifier can be deterministically completed.
What Changes
- When a login identifier is exactly 19 numeric characters and starts with
89, call/api/c/v1/auth/verify-assetwith the entered value first. - If that first request fails or does not return
asset_token, compute the twentieth digit with the ISO/IEC 7812 Luhn (mod-10) check-digit algorithm and retry verification once using the completed ICCID. - Keep the first failure entirely silent to the customer. Only the retry failure is handled by the existing login error flow.
- Persist and use the successful 20-digit ICCID for the authenticated session without mutating the text in the input field during the silent retry.
Impact
- Affected capability:
iccid-login-check-digit-retry(new) - Affected code:
pages/login/login.vue - Affected API:
POST /api/c/v1/auth/verify-asset - No backend API, request payload shape, or shared error handling is changed.
