The back-end offers the possibility to execute back-end operations for successful payments like deposit, refund or recurring payments.
Back-end operations both for QPAY Checkout Page (also referred to as Toolkit light) and QMORE Checkout Seamless allow you to use commands which enable various operations regarding the orders of your consumers or the payment process itself. These operations are called by a server-to-server request from your web server to the QENTA Checkout Server. So you have the possibility either to call these operations automatically from the back-end of your online shop or manually from your user interface you have implemented for administration purposes in your online shop.

The data storage is part of the QENTA Checkout Server. It is used to store sensitive payment data entered by the consumer during the payment process in your online shop when QMORE Checkout Seamless is used. When using this data storage you do not need a PCI-compliant online shop and web server since sensitive payment data such as credit card numbers, expiration date, etc. are directly sent from a web form in your online shop to the QENTA data storage, thus bypassing your web server. The data storage is unique to each of your consumers and is valid for 30 minutes after the latest access.
Typical financial service providers (FSP) are credit card companies, banks and banking systems. Their field of activities include accepting money transfer requests, approval or denial of transactions and processing of payments. Since every payment request needs to be processed, the payment service provider, i.e. QENTA, transmits the payment information to the respective financial service provider. The payment is approved or denied and corresponding information is sent back to the payment service provider. Merchants need to close appropriate contract(s) with financial service provider(s) depending on the payment methods they want to offer. The processed amount is transferred to the corresponding merchant’s account.
A fingerprint is a method to ensure that sensitive parameters and their values sent from your online shop to the QENTA Checkout Server and vice versa are not changed by anyone who is transferring the data over the Internet.
The front-end receives the order data of your consumer in your online shop and handles the user interface for the payment process, especially the presentation of external pages of financial service providers like internet banking pages or pages for entering the 3-D Secure code.

The Payment Card Industry Data Security Standard (PCI DSS) is a binding set of rules and procedures established by four major credit card companies (Visa, Mastercard, Discover and American Express) in 2004 and is aimed at companies that accept credit cards as payment method.

Our shop plugins are constantly updated and improved in order to be compatible with the current version of the shop systems and to offer you all available payment methods.
When the payment of a certain amount is authorized, some financial service providers offer to deposit the total amount not in one single deposit but in multiple smaller deposits. E.g. when shipping only some items of your consumers shopping basket, you can make deposits for each separate shipping up to the total authorized amount (e.g. 100 authorized, 2×50 deposited). Not to be confused with partial capture.

Security approach originally developed by Visa for online credit card payments with the main objective being the reduction of fraud and credit card abuse. By offering 3-D Secure, merchants benefit from payment guarantees and will receive the outstanding amounts even in case of a consumer payment default (a liability shift from the merchant to the card issuer takes place).
During the payment process, the consumer first enters the credit card number. A connection is established to the card issuer and the consumer is prompted to enter the 3-D Secure code which is only known to him in order to prove that he is the authorized card holder. After successful authentication, the transaction is carried out.
The 3-D Secure code is defined by the card holder during the registration process and must not be confused with the 3 or 4 digit CVC code which is printed on the back of a credit card. The most common services using 3-D Secure are American Express SafeKey, Verified by Visa, and Mastercard SecureCode.
