  1. 1.1.

  2. Payment with Visa or Mastercard

  3. The payment providers check, among other things, whether the credit card or debit card participates in the 3-D security programmes Verified by Visa or Mastercard SecureCode. These are security procedures specially developed for these card types that check whether the legitimate cardholder and the legitimate online merchant are actually participating in a transaction. If your bank carries out one of these methods, an additional query screen opens after you enter the card data. This screen is connected to your bank and additionally asks you to enter the "Secure Code" (a password chosen by you). Only with the correct password will the transaction be carried out. If your credit card is not registered for any of these procedures, the payment will be carried out without further authentication. You can find more information on credit card security procedures on: Verified by Visa or Mastercard SecureCode Alternatively, a further authentication by fingerprint for mobile devices or a TAN number is requested in the course of the order. This so-called 2-factor authentication serves the security of the order by means of a further sensible query.

  2. Payment with American Express

  3. The system checks whether the delivery address specified in the order is identical to the address that is stored with American Express as the billing address (Amex address verification system, "AVS" for short). If the addresses do not match, you will be requested in a separate e-mail to have the different delivery address deposited with American Express. Your delivery will only be sent after successful authentication. Important: For all payments by credit card or debit card, credit notes from returns will always be credited back to the credit card or account used for the purchase. You may be subject to transfer and processing fees from your respective bank. In this case, Diagen Diamond will not refund the corresponding fees.

2. Payment with PayPal

  1. Select "PayPal" in the order step "Payment & Shipping" and click on "CONTINUE". On the following page "Check & order" you will be automatically redirected to PayPal by clicking on "Buy PayPal now". If you are already a PayPal customer, you can log in there with your user data and confirm the payment. If you do not yet have a PayPal account, you can open a PayPal account and then confirm the payment. Credits from returns are always credited back to the PayPal account used for the purchase.

3. Payment by SOFORT Überweisung (Klarna)

  1. SOFORT Überweisung is a direct transfer method and allows you to pay quickly and without additional registration. All you need is a bank account and online banking access.
