In the Netherlands, iDEAL is the most popular online banking payment (before the card payment method). Created in 2005, the total amount of the transactions processed in 2016 is 1 billion which represent 60% of the market share in the country.

This payment method has been created and launch by a consortium of Dutch big banks: with 11 participating banks, iDEAL covers the major part of online banking in the Netherlands.  

Based on Sepa Credit Transfer (SCT), iDEAL payments can be done into any IBAN bank account in Europe. 

How does it work?

SlimPay offers the activation of Direct Debit through an iDEAL transaction by using the initial transaction as a consent to sign a mandate and allow recurring payments. It is more secure for the end-customer, payments are guaranteed and irrevocable.

It is based in generating a prefilled Credit Transfer (SCT) that the consumer validates and signs on his bank website (redirection from iDEAL to the appropriate bank) in order to confirm the transaction.

To process iDEAL transactions, the following steps are required: 

  • User selects payment method on SlimPay Checkout screen
  • User is redirected to his/her bank login for authentication (the bank's authentification acts as a mandate signature
  • User authorizes a 0,10€ iDEAL transaction
  • If successful, user is redirected to SlimPay success screen
  • Signed Direct Debit mandate is sent by email


Timeline and cut-off times: If the SCT is triggered before 3pm, the amount is available for the merchant on D+1; if the SCT is triggered after 3pm, the amount is available for the merchant on D+2. 

Possible uses cases
