  • They diverge on capability: Aiia covers Bank account data access, Paymentology covers Global issuer processing.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Aiia

  • It is now part of Mastercard rather than an independent company, so a business specifically wanting to avoid card network dependency in its banking infrastructure no longer gets that separation by choosing Aiia.
  • Pricing is not published and requires engaging Mastercard's open finance sales process, which can be a heavier sales motion than dealing with a smaller independent open banking provider.
  • Its strongest bank coverage remains concentrated in the Nordics and Northern Europe, so companies needing dense coverage in Southern or Eastern Europe should verify current bank connectivity before committing.
  • Brand confusion is real: developer documentation, login portals and older case studies still reference "Aiia" while newer Mastercard material refers to "Mastercard Open Banking," and a company researching either name in isolation may miss half the relevant material.
  • As with any open banking platform, reliability still depends on the consistency of the underlying banks' own APIs, which is a systemic industry issue rather than something Aiia specifically controls.

Paymentology

  • Paymentology processes but does not hold issuing licences, so every market still needs your own licence or a sponsor bank, which is usually the slowest and most expensive part of a launch.
  • Fees include per active card charges and monthly minimums, so a portfolio with many dormant cards pays for plastic that generates no interchange.
  • Certification, settlement and scheme relationships differ by country, so a multi market rollout is a series of separate projects rather than one integration.
  • As a processor it sits between your product and the networks, meaning outages and scheme mandate changes reach your cardholders through a party you do not control.
  • Documentation and developer self service are weaker than the United States hosted processors, so early integration depends heavily on Paymentology implementation staff.
