This is where the shoe pinches a little bit. DigID can be used by anyone, but if you want to use iDIN you will have to be a customer of one of the following banks: ABN Amro, ASN, ING, Bunq, Rabobank, Regiobank, SNS or Triodos. And then you will also need to use online banking or mobile banking. So, there you are as a Knab customer. You just have to hope that your casino still offers an alternative method to register. Especially the slightly older customers of bingo platforms, for example, can be greatly inconvenienced by this.
