The roots of US debit infrastructure trace back to regional banks' ATM sharing networks in the 1980s, and STAR emerged from that era, growing through acquisitions and consolidation into one of the largest PIN debit networks in the country, with thousands of participating financial institutions. Thanks to that vast base of participants, a large share of US debit cards connect to the STAR network, but its presence lives at the ATM and back-end payment layer — it has never developed into a consumer-facing online payment brand.

It's a mistake to read this scale as meaning "integrating STAR captures US debit customers." STAR isn't an option in an online merchant's checkout, and US debit demand is covered through the standard combination of general card payments and wallets. Even when an online transaction does route through the STAR network, it's only involved at the back end through PINless routing.

When a US consumer pays online with a debit card, the transaction is routed — as determined at the routing layer — through a card network or a PIN debit network such as STAR to obtain issuer approval. Which network is used isn't shown to the consumer or merchant, and it doesn't change the payment experience. The approved proceeds are collected by Hecto Financial in USD, converted, and paid out in the currency set under the contract.

Contracting and integrating STAR as an individual payment method is unlikely to be a viable structure from Hecto Financial's perspective. Accepting US debit customers is already sufficiently covered by general card payment integration, and routing through STAR is decided automatically at the routing layer. Your overall payment setup for the US market can be worked out in consultation with the sales team.

• Sales channels

  Integration method and priority vary depending on your mix of online sales channels — owned site, marketplace, mobile app, and so on

• Product categories

  Advance confirmation is needed on whether your category falls under STAR's merchant restrictions

• Local regulatory compliance

  Confirmation is needed on compliance with US payment and foreign exchange regulations, including federal and state consumer protection rules and card network rules (see official sources below)

Settlement for transactions routed through the STAR network also follows the standard structure for US card payments. That is, Hecto Financial collects the USD proceeds, converts them, and pays out in a single currency selected from USD, KRW, or JPY under the contract, with settlement cycle, fee rate, and refund deadlines all governed by contract terms. Differences at the network layer don't change the merchant's settlement terms.
