Q&A
| Question | Answer |
| Why can’t I see my personal details in the
Digidentity Wallet? |
Digidentity is the Trust Center (TC) for SERMI.
Within the SERMI scheme, the TC is not permitted to know your identity. Only your conformity assessment body (CAB) holds this information. This information is not shared with Digidentity.
Your SERMI account in the Digidentity Wallet will never contain any personal information (name, email, date of birth). Only your unique identifier (UID) is visible. This ensures that your identity remains anonymous to Digidentity. |
| I’ve accidentally entered my email address and/or uploaded my identity document after downloading the Digidentity Wallet App, what should I do? | If you upload your identity document or add your email before scanning the QR-code invitation from your CAB, the Digidentity Wallet will notify you (‘different user’). This message will appear after you scan the QR-code from your CAB.
You can still register for your SERMI certificate. However, it will be created within a new, additional account. It is optional to delete your non-SERMI account:
Always confirm that you are deleting the correct account. Your SERMI account will contain your SERMI Service Card. (see chapter 2.3). This is visible in the Digidentity Wallet after logging in. Do not delete accounts if you still need the services in it. |
| What is the validity period for the QR code in my
SERMI invitation? |
The QR code in your SERMI invitation is valid for 28 days
from the date it is issued. After this period, the QR code |
| will expire, and you will not be able to use it to activate your certificate.
In this instance, you must request a new invitation from your Conformity Assessment Body.
To avoid expiration issues, we recommend that you activate your certificate immediately upon receiving the invitation from your CAB. Prompt activation helps ensure that your registration is completed within the QR codes validity period. |
|
| What happens if I lose access to my certificate/device? | If you’ve lost access to your SERMI certificate, you will need to contact your Conformity Assessment Body (CAB) to request a new invitation. Your CAB can reset your certificate and issue a new QR code for reactivation.
