Feature overview

Three different integration flows are available for signing on the BankID OIDC platform. Each flow offers a subset of features summarized in the table below.
The two full flow alternatives give support for the most advanced use cases through utilization of the SignDoc resource server. The simplified flow is an easier integration alternative but is limited to text signing.

	PAdES	SEID-SDO	Simple-text
Envelope	PAdES	SEID-SDO
Signature types	Combined end user and merchant signature End user signature only	Combined end user and merchant signature	Combined end user and merchant signature
Document types	PDF	Text XML PDF	Text (limited length)
Number of documents	Multiple	Multiple	Single
Identity Providers	BankID netcentric	BankID netcentric BankID on mobile (single text only, max 118 characters)	BankID netcentric (max. 150 characters) BankID on mobile (max. 118 characters)
Multiple end user signatures in same envelope	Serial signing (PAdES increments)
Customization	User interface options Timeout for the user signing Configuration of visible seals	User interface options Timeout for the user signing
Result content	PAdES envelope PAdES appendix Document hash	SEID-SDO envelope Basic signature Document hash	Basic signature Document hash

A different subset of the signing functionality is available directly through BankID Server implementations. See Signing compatibility matrix for comparison.

A note on BankID on mobile - now deprecated

BankID web client (netcentric) is the default identity provider used for signing. For text-only signing (Simple-text or SEID-SDO) it is possible to use BankID on mobile instead - for a limited time only as BankID on mobile is going away.

In order to use BankID on mobile, the authorization request must contain login_hint=BIM[:[phoneNumber][:birthDate]] as a query parameter.

BankID on mobile has the following limitations:

Only supports text signing (simplified flow)
The text can be maximum 118 characters long.
Only the following character set is supported:
[0-9] [a-z] [æ] [ø] [å] [A-Z] [Æ] [Ø] [Å] [ ][CR] [LF] [#] [$] [%-&] [(-?] [@] [¡] [£] [¤] [¥] [§] [¿] [Ä] [Ç] [É] [Ñ] [Ö] [Ü] [ß] [à] [ä] [è] [é] [ì] [ñ] [ò] [ö] [ù]
