Norway's BankID and Sweden's BankID are different products by different companies that happen to have the same name.

Sweden did briefly have a SIM card-based version of its BankID, but it was quickly replaced with the smartphone app-based “Mobile BankID”.

Really?

In Norway BankID is quite definitely connected to the SIM card.

In Switzerland we have MobileID which is basically the same thing as Norway's Bank If : using a sim card as a smart card.
