Netflix without credit card, direct debit or Paypal?

I want to create a Netflix account so I bought a voucher worth 15 euro. However, Netflix tells me that I should first specify a payment method (credit card, Netflix or Paypal). Is it really necessary or am I just too stupid? I do not have a bank account because I'm still relatively young and still go to school.

That would be completely stupid I mean in other services, such as Spotify, Amazon, Google or Dazn you do not have to finally give his account information or there are people who simply do not want to share their data with every company.

If Netflix asks, Netflix wants to know your age. If your parents set up the account for you, that should not be a problem for you to pay with a voucher.

You have to enter the data also with voucher. You are subscribing, the provider wants to make sure that you continue to pay nicely if you forget to cancel your subscription and that you are of age, because as a minor you can't close such contracts.

Thus you have had bad luck.

You need to complete a payment method so that Netflix is secured, even if the coupon is empty you can still pay.

But it's handicapped by Netflix. First, no other streaming service does that, and secondly, they lose potential paying customers, like me.
