Payment by credit card is the most widely used means of payment in the world of e-commerce, with a predominance of international Visa & Mastercard networks that coexist with domestic networks (CB for France, Bancontact for Belgium, etc.).

Some cards may belong to several networks (for example cards co-badged with CB and VISA). A European regulation (Multilateral Interchange Fee, or MIF) gives you the possibility to make a default brand choice, but the end customer can change this choice when he is on the payment page. This regulation concerning the selection of the brand has an impact on the payment pages which must present this choice when the card entered for payment is concerned by this regulation (co-branded card) .

You have the option of splitting a transaction into several parts, which will be sent to the bank at specified intervals.

In case of agreement, the transaction in question is sent for capture. In case of refusal, the transaction is not submitted again.

The validation function makes it possible to trigger the transaction capture. It also enables you to defer a payment so the customer's account is debited only when the purchased goods have been dispatched.

If the chosen method for sending the bank transaction is not automatic, you have to validate every transaction manually. If you do not validate a given transaction before its chosen capture time (as selected) ends, this transaction will expire. It will then be impossible for you to send it to the bank.

You can validate all or part of the transaction amount. The amount validated will be captured on the day of its validation. It is of course impossible to validate an amount that exceeds the initial amount of the transaction.

Having clicked on the validation button of a transaction in the list of results or on the button in the seleted transaction details, the following page will display:

Enter the amount to be validated in the following field:

Click on .

The following page below will then display if the validation is successful:

If the validation has failed, the following page will display:

This function makes it possible to change the amount to capture. For you, it is useful for inventory management purposes. When a customer has cancelled several products that are part of a single transaction, you can cancel the latter partially. In this case, the amount cancelled will be that of the unavailable product, and the customer will only be charged for the products that were actually delivered.

Transactions can only be cancelled before they are captured. A transaction cannot be cancelled if it has already been captured. However, refunding the customer fully or partially is still possible.

By default, deferred capture is inactive (0 days), which means that the capture is carried out on the same day as the transaction. To defer the date on which transactions are captured, you have to make sure that this setting has been configured correctly.

When a cancellation is requested, the Mercanet server checks two parameters:

• The amount. An amount that is higher than that of the original transaction cannot be cancelled.
• The transaction cancellation period, which is set at the time of payment. Beyond this period, the transaction is captured and can no longer be cancelled.

A transaction can be cancelled several times provided the transaction capture deadline is not overdue and the transaction balance is not null.

In the case of a partial cancellation, the balance of the transaction is automatically captured after the capture time is up.

Having clicked on the cancellation button of a transation in the listof results or on the button in the selected transaction details, the following page will display:

Enter the amount to be cancelled:

Click on .

The following page will then display if the cancellation is successful:

If the cancellation has failed (the amount is higher than the amount of the initial transaction), the following page will display:

A refund makes it possible to credit the account of a customer that was unduly charged (if the product was not delivered, is unavailable, damaged, returned, etc.).

The customer's account will be credited with the refunded amount, and your account will be debited with the same amount. The refund is captured on the same day. The refund is captured on the same day it is entered in Mercanet Back Office.

You can refund a customer for a period of fifteen months following the order. You can make an unlimited number of partial refunds, provided these fifteen months are not exceeded and the balance is not null.

After you have clicked on the refund button of a transaction in the list of results or on the button in the selected transaction details, the following page will display:

Enter the amount to be refunded:

Click on .

If the refund is successful, the following page will display:

If the refund has failed (the amount is higher than that of the initial transaction), the following page will display:

You can create a new transaction using an old transaction.

Duplicating a transaction is possible up to 18 months after its creation date and provided the expiry date for the means of payment has not been exceeded. The transaction created during the duplication is a new transaction. All of the characteristics of this transaction can be changed, with the exception of the card information, which you does not need to store in your IT system. A transaction created by duplication can in turn be duplicated.

Duplicating a transaction requires a new authorisation request, using the payment information (card number, account number etc.) corresponding to the original transaction. The future of a duplicated transaction does not under any circumstances depend on the result of the original transaction: if the initial transaction was refused, it is possible that it is accepted after duplication, and vice-versa.

Any transaction associated with payment in instalments can be duplicated. Payment of this new transaction will be completed in one instalment only.

For example, if a transaction, either by error or omission, was not validated in the capture time you set, it has expired and will therefore not be paid. You may wish to secure this transaction, thererfore you have the option of duplicating an expired transaction. Provided it is authorised, this new transaction will be paid for.

Therefore, this operation can allow you, among other things:

• to replay transactions without having the cardholder's card details
• to catch up on expired transactions, i.e. transactions that would not have been validated in time (in VALIDATION mode)
