Where each one falls short

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

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.

Temenos Transact

  • The codebase originates in the 1990s, so banks on older releases face major upgrade programmes to reach current versions, and many defer them for years.
  • Total cost is dominated by implementation partner fees rather than licence, and those programmes routinely overrun their original estimates.
  • Product changes that cloud-native cores treat as configuration can require development work and a release cycle, which slows time to market for new products.
  • Heavy customisation is common and it makes every subsequent upgrade harder, creating a compounding cost that banks feel a decade after go-live.
  • Temenos has repeatedly restructured its product line and naming, so buyers must check carefully which components a proposal actually includes and which are separately licensed.

Answered from the vendors’ own pages

Paymentology: Does Paymentology provide the BIN and licence?

No. You need your own issuing licence or a sponsor bank in each market; Paymentology processes the transactions.

Temenos Transact: Is Transact the same as T24?

Yes. T24 was renamed Temenos Transact; older installations and much of the consultant population still use the T24 name.

Paymentology: What is the actual pricing model?

Per transaction and per active card, with a monthly minimum. Dormant cards still cost, so model your activation rate.

Temenos Transact: Can it run in the cloud?

Yes, it is offered on public cloud, though many existing installations remain on-premises and moving them is a project.

Paymentology: Why choose it over a United States issuer processor?

Network certification and live programmes in markets where those processors do not operate, which decides feasibility rather than preference.

Temenos Transact: What drives the cost?

Licence scaled by size, annual maintenance as a percentage of licence, and implementation partner fees that usually exceed the software cost.
