The Problem

The Healthcare Payments
Layer Is Broken

The infrastructure between your HSA card program and healthcare merchants was built for a different era. It's costing you — and your cardholders — every single day.

Compliance Burden Is Unsustainable

Manual IIAS/SIGIS verification, after-the-fact substantiation audits, and paper receipt collection create operational overhead that scales with every transaction.

80%+ compliance cost eliminated with Howlite auto-substantiation

2–5 Day Settlement Float

Traditional batch processing means providers wait days for funds. The settlement window creates chargeback exposure, stresses cash flow, and adds wire fees on every transaction.

Howlite compresses settlement to T+0 — 24/7, including weekends

Interchange Eating Your Margins

2.5–3.5% per transaction adds up to hundreds of thousands annually. Legacy card networks embed hidden fees at every step — assessment surcharges, network fees, and more.

How It Works

Invisible Middleware.
Visible Impact.

Howlite operates beneath the surface of every HSA transaction. No new card. No merchant integration. No consumer re-enrollment. It just works.

01

Consumer Pays

Member uses their existing HSA Visa or Mastercard. No new card. No app required.

02

Howlite Enriches + AI Reviews

Transaction intercepted on existing rails. FHIR fields, ICD/CPT codes, and eligibility attached — then AI scans the claim for billing errors, upcoding, and duplicates before approval.

03

Smart Approval

Member sees eligibility, plan coverage, and HSA balance. Approves with full context. Zero surprises.

04

USDC Settlement

Provider receives funds as USDC on Hedera — same day, every day. No banking-hours restriction.

05

PHR Updated

Transaction data flows into consumer's Personal Health Record automatically — ICD/CPT coded and archived.

The SmartHSA Bank Advantage

AI Claims Intelligence

FHIR Data + Machine Intelligence.
Every Error. Caught Before It Costs You.

The richness of FHIR data isn't just about compliance — it's the raw material for AI that reviews every claim and EOB for billing errors, upcoding, and duplicate charges. In real time. Before funds move. Every stakeholder in the ecosystem wins.

Durbin AmendmentActive Law

Requires banks with $10B+ in assets to enable multiple debit routing networks. Established the regulatory framework that makes Howlite routing legally mandated choice — not a workaround.

Credit Card Competition ActPending · Bipartisan

Extends Durbin-like routing requirements to credit cards. Bipartisan support signals significant TAM expansion. Early adopters of alternative routing infrastructure capture structural advantage before compliance becomes non-optional.
