You can pay for your order by credit card (Visa and MasterCard) with Stripe, via PayPal or by bank transfer. Your payment information is secure, as all transactions are handled by the international payment service and sent encrypted to your bank.
As for import taxes, if your order is within the European Union, you will not have to pay customs charges or import taxes. However, orders within the EU are subject to VAT, which is already included in the product price.
