Stripe supports some Direct Debit solutions:
https://stripe.com/docs/payments/bank-debits

Which means you provide your account details and updown can charge it automatically (so this method would support auto-renewal like with cards).

I create this suggestion to poll the interest in this solution. Keep in mind it is already possible to pay by SEPA Transfer (where you manually send money to our IBAN) by contacting me. So this suggestion is only for people who would prefer an automatic charge on their account.
