The short version

  • Each has a real cost: Episode Six deployment on premise or in a private tenancy means the institution carries infrastructure, upgrade and PCI scope work that a hosted processor would absorb.; 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.
  • They diverge on capability: Episode Six covers Tritium API platform, Highnote covers Card issuing.
  • 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.

Episode Six

  • Deployment on premise or in a private tenancy means the institution carries infrastructure, upgrade and PCI scope work that a hosted processor would absorb.
  • Implementation runs to quarters and involves core banking, network certification and fraud system integration, so time to first card is far longer than with a self serve issuer processor.
  • Pricing is entirely bespoke and weighted to large programmes, which prices out fintechs and small issuers who would be better served by a hosted platform.
  • Being smaller than the incumbent processors, its network certifications and operational presence vary by region, so a global rollout can find gaps in specific markets.
  • The flexibility of six hundred APIs and a configurable product engine shifts design responsibility onto the buyer, and institutions without strong internal payments architects end up dependent on professional services.

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.

Answered from the vendors’ own pages

Episode Six: Can Episode Six run inside our own data centre?

Yes. On premise and private cloud deployment is the main reason banks choose it over hosted only processors.

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.

Episode Six: Is it suitable for a startup issuing its first cards?

Not really. The licence, implementation timeline and cost are aimed at banks and large institutions.

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.

Episode Six: Do we still need a card licence or sponsor?

Yes. Episode Six is a processor. Network membership, licensing or a sponsor arrangement remains your responsibility.

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.
