Push credit transfer

Introduction to the Push Credit Transfer

As we have already seen, the initiation of the credit transfer involved:

• the authentication of the payer, that is the authentication of the owner of the account (required by the bank or regulation)
• the trigger of the credit transfer.

In practice, banks often combine these steps so that authentication triggers the credit transfer.

Definitions

A "Push credit Transfer" is a credit transfer where:

• the credit transfer is initiated by the payer
• authentication is performed by the payer (mandatory)

Proposal for WebPayment Push Credit Transfer

In order to cope with the issues previously highlighted, we propose a flow diagram.

Even if those flows give improvements, several issues remain:

1. account of the payee must not be tampered during the flow (1), if not the money will reach another account
2. the merchant should be able to control the validity of the information of the bank (that is the data of the payment status report) in order to ensure that the credit transfer is correctly initiated

Furthermore, it is impossible for the merchant to finally change the amount (for example, if part of items are not available at same time) or to delay the payment. Some legislation requires payment delays in order to synchronize payment and delivery.
