AISP vs PISP - what's the difference?

Open Banking allows merchants to interact with their clients’ bank accounts, in order to:

  • Initiate payments.

    OR

  • Make account access requests.

Third-Party Provider

Nuapay is a Third Party Provider (TPP).

As a TPP, Nuapay:

  • Facilitates the interaction between the Merchant, the merchant’s User (also referred to as a PSU) and the PSU’s bank (also referred to as the ASPSP).
  • Acts in two modes: as a Payment Initiation Service Provider (PISP) or as an Account Initiation Service Provider (AISP).

PISP

When acting as a PISP, merchants can request clients to make payments via Open Banking.

For end users they:

  • Select Open Banking as the payment method on your payment page.
  • Select the bank where their account is held.
  • Are redirected to this bank’s online banking service.
  • Verify themselves by providing their online banking credentials (as they would normally do when logging on to their online banking system).
  • Select an account from which the payment will be taken (where the customer has more than one account with the bank).
  • Confirm the payment amount.
  • Are then redirected to the merchant’s confirmation page.
  • The PSU account is debited and the merchant account is credited.

AISP

When acting as an AISP, merchants can request clients to grant access to their account information via Open Banking.

For end users they:

  • Select Open Banking Account Access on your merchant page.
  • Select the bank where their account is held.
  • Are redirected to this bank’s online banking service.
  • Verify themselves by providing their online banking credentials (as they would normally do when logging on to their online banking system).
  • Select an account to share and confirm their consent to allow the merchant to access the account details, balance and/or transaction information.
