Credit Card - Mail Order and Telephone Order

General information

This payment method is intended for your back office offering your consumers the possibility to purchase services or articles without having to disclose their credit card details via the web browser e.g. visiting the online shop from a publicly accessible computer in an internet café.

Furthermore, this payment method is suited for any other system that is capable of storing orders, such as ERP systems and call center applications.

As for online shops, consumers have basically two options to order products or services:

  1. Per mail, fax or letter: Consumer forwards the order and the payment method details to you in written form.
  2. Per telephone: Consumer calls your service center to place the order and communicates the payment method details by telephone.

Handling Mail Orders and Telephone Orders

There are three possibilities to handle credit card transactions based on mail and telephone orders:

  • Integration of this payment method into your online shop, call center application, etc. and only accessible for entitled persons such as the customer care team.
  • Wirecard Checkout Terminal
  • Wirecard Checkout Automated

Please note that these solutions are used in your back office only and that your staff must have received a special security training for handling sensitive consumer and payment data.


After corresponding programming and integration directly into your online shop, call center application, etc. without any need for additional interfaces or solutions, consumers e.g. to your online shop may call your service center and place orders by telling your service center staff the credit card details by phone or by sending in a fax. Thus this payment method is only available to your service center staff and is not accessible by consumers who visit your online shop.

This payment method must only be used in your back office. Consumers must never disclose their 3-D Secure code to the service center staff when placing mail order telephone orders. Therefore, this payment method must never be offered to the consumers in your online shop because this would circumvent 3-D Secure processing. Also, issuers forcing card holders to use “3-D Secure only” may decline such transactions.

Please be aware that your merchant configuration has to be changed by our support teams on your behalf in order to use this payment method. Apart from having this payment method enabled by our support teams, you need to conclude acceptance contracts with your acquirers who might require you to meet additional and special conditions to fulfill PCI security standards.

As a further advantage and if your online shop is connected to an ERP system, the service center staff may verify whether the products which are ordered via phone or fax are available while at the same time checking the validity of the consumer's credit card data and online shop account details.

Please refer to transaction-based operations by payment method and non-transaction-based operations by payment method for further information and details on back-end operations in Wirecard Checkout Page and Wirecard Checkout Seamless.

Wirecard Checkout Terminal

Wirecard Checkout Terminal is optimally suited for your needs if consumers to your online shop prefer telephone orders. Payment details of your consumers are entered in the web-based, password protected Wirecard Checkout Terminal interface and are processed automatically and immediately during the telephone order process. Furthermore, it is possible to obtain an immediate confirmation that the payment has been processed while the consumer is still on the phone, i.e. any incorrect information or typing mistakes can be rectified at once.

Wirecard Checkout Automated

Wirecard Checkout Automated is best suited for your needs if you have to handle a lot of mail orders. Wirecard Checkout Automated is intended for non real-time critical applications such as catalog orders, recurring payments and subscriptions.
