More information about BankID:

Merchant certificate

​​​​​Nets through the Signing and Identification Services are resellers of BankID merchant certificates, and this can be ordered either separately or together with E-Ident and/or E-Signing. When ordering a merchant certificate through Nets, you will receive an information letter asking you to complete a form with information needed to create a BankID “brukerstedsavtale” with BankID Norge. ​Note: In this form you need to ​specify if you are allowed to handle SSN. 

The form shall be returned to our support and based on the form Nets will register this order at BankID. After the registration you will be asked to confirm and sign the order. When the order is signed with BankID Norge, it will be sent to your bank for processing. Your bank may use up to 10 business days for processing the order. Nets will  then recei​ve activation information for your BankID merchant certificate from your bank. The merchant certificate will be activated and connected to your configuration.​

In cases where you use another reseller, the BankID activation link and code must be sent to Nets without activating it. Contact Nets support to get contact details of recei​​​ver of the link and code. 

Test merchant certificate

Nets will set you up with a common test merchant certificate if nothing else have been agreed. ​

​​All companies that are allowed to handle social security numbers (SSN) can get this in return after a BankID identification.

For customers using OIDC, SSN will only be returned if scope=ssn is set in the identification request. Read more about the optional eID specific scopes and identification request parameters for OIDC and SAML respectively.

Note: Remember to specify that you want to process SSN when ordering your BankID merchant certificate and giving Nets your E-Ident configuration details.

​IFRAME sizes

The recommended and minimum IFRAME sizes from BankID are:

  • Large screen (Desktop/tablet): 396px (w) by 280px (h) (recommended) / 370px (w) by 204px (h) (minimum)
  • Small screen (Smartphone) (only minimum sizes): 320px (w) by 350px (h) (portrait) / 480px (w) by 200px (h) (landscape)

CSS file adjustment

The BankID client should be styled with CSS to display properly. The default styling has CSS rule that set the proper sizes. Styling can be overridden either by setting av style URL in the customer configuration at Nets or by sending a style parameter when starting the identification. The default CSS styling sets width and height to 100%. The client will then expand to fill the container (iframe), regardless of the container size.

When overriding styling, the sample CSS below will produce the same effect as the default styling.

#nobankid_index_html {
    height: 100%;
    overflow-y: hidden; /* make sure no scroll bar is shown */
#nobankid_index_html .iframe,
#nobankid_index_html .iframe .ipage {
    height: 100%;
#nobankid_index_html .iframe .ipage .main {
    height: 100%;
    min-height: 200px;
