Payment Initiation Service Provider mode

Initiating payments via Open Banking offers numerous benefits.


For Merchants

  • Open Banking charges are much lower than a card payment.
  • No PCI-DSS requirements.
  • No sensitive customer data is ever transmitted or stored on your server.

For your clients

  • No need to key in credit card, expiry and CVV details.
  • Card limits are not applicable.
  • Added confidence that the payment is secure as the actual authorisation takes place on the user’s online banking portal.
  • Potential for card details to be stolen or hacked is eliminated.
  • The merchant doesn’t hold any of your personal financial details.

  • Checkout
  • Redirect
  • Self-Hosted
  • Self-Hosted-Callback

These implementation modes are described in greater details in PISP Implementation Options.
