Pay by Bank is a US account-based payment method in which the consumer directly links and authorizes their bank account to send funds account-to-account (A2A). It is a method still in its early growth stage, built on the account-linking technology of open-banking providers such as Plaid and the spread of the FedNow and RTP real-time payment rails, so it's important to set expectations realistically when considering it.
US payment infrastructure is resolving the speed limitations of account-based payments as the Federal Reserve's FedNow (launched 2023) and The Clearing House's RTP expand real-time payment rails. Pay by Bank is a payment form built on these rails that combines open-banking-style account linking and balance verification; it's drawing attention because it bypasses card networks, giving it a different fee structure, but consumer awareness is still at an early stage.
It's worth considering first for high-value transactions where card fee burden is significant, and for fintech, investment, and rewards services where account-based funding feels natural. Rather than positioning it as a primary payment method, it's more realistic to place it alongside cards and wallets as a cost-saving option and adjust its placement based on observed usage trends.
When a consumer selects their bank on the payment screen and links their account through online banking authentication, the balance is checked and per-transaction transfer approval follows. The transfer is processed either in real time or on an ACH schedule, depending on the bank and rail combination, and once received, Hecto Financial takes the funds in USD, converts them, and pays out in the currency set in the contract. Because the bank authentication itself serves as identity verification, this is a different authentication scheme from card-based 3-D Secure.
Through Hecto Financial, businesses in Korea can also explore accepting US A2A payments, but Pay by Bank is a method still in its early growth stage where actual usability varies depending on provider and bank coverage. It's recommended to specifically confirm the range of supported banks, the processing rail, and expected usage rates with the sales team before contracting.

Once USD originating from the consumer's account is received by Hecto Financial, it is converted and settled in whichever of USD, KRW, or JPY was selected under the contract. Transactions routed over real-time rails tend to have funds confirmed quickly, but the settlement cycle is a separate contract term, and since refunds are processed as a reverse transfer back to the original account, the process differs from card refunds and should be reflected in your operations manual.
Hecto Financial's team will work with you to review the right combination of payment methods for the US market.
