In order to allow you to secure your security deposit or down payment online without being charged and without impacting your credit card limit, we perform a pre-authorization of 1€ on your bank account. This allows us to verify that your credit card is not a stolen, lost, expired, etc.
Depending on your bank, a debit line "-1€" may appear on your bank statement. In this case, a new credit line will appear within 15 days. This is a pre-authorization, not a payment.
