I already have Vipps number Open amount. Can I still use it?

Yes. Your solution still works. It will be phased out gradually, but the launch of the new Vipps number does not require you to switch now.

The fact that new Vipps numbers let customers enter the amount themselves does not mean your existing Vipps number Open amount has been moved over automatically.

If you want to combine Open amount and Shopping basket, you can order a new Vipps number in the business portal.
