Where each one falls short

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

Highnote

  • Card issuing requires a sponsor bank, and that bank sets programme approval, compliance obligations and often minimum volumes, so a small programme can be rejected regardless of technical fit.
  • Pricing is entirely quoted, including platform fees, per active card charges and monthly minimums that do not appear on the website, so the true cost per card is only visible late in a sales process.
  • Interchange sharing is the real revenue model for most customers, and the split is negotiated, capped for regulated debit under the Durbin amendment and sensitive to your spend mix, so revenue projections built on headline interchange rates overstate income.
  • Running issuing and acquiring with one provider concentrates risk: an outage or a compliance action affects both money in and money out at the same time.
  • Highnote is a younger company than the established issuer processors, so long term programme continuity, network certifications in new geographies and international coverage are thinner than the incumbent alternatives.

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

Highnote: Do I need a sponsor bank?

Yes for card issuing in the United States. Highnote is a processor and programme platform, not a bank, and the sponsor bank sets approval and compliance terms.

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.

Highnote: How do customers make money on a card programme?

Mostly interchange sharing. Negotiate the split explicitly and model it against your actual spend mix, since regulated debit interchange is capped.

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.

Highnote: Can Highnote handle both accepting and issuing payments?

Yes since its 2025 acquiring launch, on the same ledger, which is its main structural differentiator.

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.
