Pay by Bank is a checkout option that pulls money straight from your checking account to a merchant’s account, using your bank’s own app or website to approve the transfer instead of a Visa or Mastercard number. Third-party providers such as Plaid, Trustly, and Fiserv sit between the merchant and your bank, and most U.S. transactions currently settle over the ACH network, with instant payment rails expanding.1Board of Governors of the Federal Reserve System. Pay-by-Bank and the Merchant Payments Use Case Because no card is involved, the fees, timing, and legal protections around the payment are not the same as a card purchase.
What Happens When You Use It at Checkout
The flow is the same whether you’re on a website, in an app, or at a physical register. You pick Pay by Bank as the payment method. A list of participating banks appears, and you choose yours. The system then hands you off to your bank’s own login screen.1Board of Governors of the Federal Reserve System. Pay-by-Bank and the Merchant Payments Use Case
Inside your bank’s app or site, you see the merchant’s name and the exact amount. You approve using whatever your bank normally requires: a fingerprint, face scan, or passcode. Your login credentials never leave your bank. The merchant and the third-party provider don’t see them.1Board of Governors of the Federal Reserve System. Pay-by-Bank and the Merchant Payments Use Case
Once you confirm, you’re returned to the merchant with a receipt. From your side it takes seconds. What happens between the banks is a separate question, and the answer depends on which payment network handles it.
How Fast the Money Actually Moves
Three rails carry Pay by Bank transactions in the United States, and they don’t all move at the same speed.
Most Pay by Bank payments today ride the Automated Clearing House. Standard ACH settles the next banking day, and same-day ACH is available too.2Federal Reserve Financial Services. FedACH Processing Schedule Your bank may take extra time to release funds to the recipient, but the interbank leg is faster than many people expect.
FedNow, the Federal Reserve’s instant service, settles in seconds with a 20-second timeout ceiling. The receiving bank must make funds available immediately once the payment clears, and it runs 24/7, including weekends and holidays.3FedNow Explorer. Understanding the Payment Timeout Clock The Clearing House’s RTP network works the same way: seconds to settle, running continuously, with immediate confirmation to both sides.
The practical upshot: if you’re checking out on ACH, treat it like a debit that will finish clearing tomorrow. If the provider uses FedNow or RTP, the money is gone from your account and available to the merchant in seconds.
What It Costs and What Limits Apply
Pay by Bank generally doesn’t charge you a fee for the transaction itself. The catch is what happens when the account can’t cover it. If your balance is too low, the transfer will typically fail, and some banks charge a non-sufficient funds fee for the failed attempt, commonly $10 to $35, though many large banks have reduced or dropped these fees in recent years.
The transfer size is capped, and the cap that matters is your bank’s. Even where the underlying network permits very large payments, individual banks set their own lower per-transaction and daily limits based on their risk policies.4FedNow Explorer. FedNow Service Increases Network Transaction Limit Expect stricter limits on new accounts or on the first transfer to a merchant you haven’t paid before. Your account terms or customer service will tell you the actual numbers.
What Protections You Have If Something Goes Wrong
This is the part worth reading before you use Pay by Bank for anything large. Card and bank-transfer purchases are protected by different laws, and the difference is not small.
How This Compares to a Credit Card
On a credit card, the Fair Credit Billing Act lets you dispute unauthorized charges, billing errors, and charges for goods that were never delivered or arrived not as described. Your liability for unauthorized charges is capped at $50, and during the investigation you withhold payment on the disputed amount. The issuer can’t report you as delinquent or close your account while the dispute is open.5Consumer Advice – FTC. Using Credit Cards and Disputing Charges
How Regulation E Applies to Pay by Bank
Pay by Bank is an electronic fund transfer, so it falls under the Electronic Fund Transfer Act and Regulation E. If someone makes an unauthorized transfer, your maximum liability is $50, but only if you tell your bank within two business days of learning about it.6GovInfo. 15 USC 1693g – Consumer Liability Wait longer and your liability can rise to $500. Miss the 60-day window after the statement showing the transfer, and you can be liable for the full amount of anything that happens after that window closes.7eCFR. Regulation E Section 205.6 – Liability of Consumer for Unauthorized Transfers
The CFPB has said that when a scammer tricks you into handing over your bank access and then initiates a transfer, that transfer counts as unauthorized under Regulation E, so the liability caps still apply.8Consumer Financial Protection Bureau. Electronic Fund Transfers FAQs
The difference from a card is the direction the money is sitting. With a credit card, you keep the money while the dispute is investigated. With Pay by Bank, the money is already gone, and getting it back depends on your bank finishing an investigation that can take up to 10 business days, or up to 45 days if the bank issues a provisional credit while it keeps looking.9eCFR. Regulation E Section 205.11 – Procedures for Resolving Errors
One boundary worth naming: Pay by Bank does not give you a right to dispute a payment because the item was defective or not as described. That protection exists on credit cards under certain conditions; it does not exist here.
Refunds and Chargebacks
Because no card network is involved, there is no chargeback. A refund is a fresh transfer going the other direction, which the merchant has to initiate. ACH refunds take several business days. A refund sent over FedNow or RTP can arrive in seconds if the merchant’s provider supports instant returns.
If the problem is an error rather than a fraud claim, such as being charged twice or the wrong amount, report it to your bank fast. Regulation E requires the bank to acknowledge your notice and begin investigating within 10 business days. If it needs more time, it can take up to 45 days, but it must provisionally credit the disputed amount within 10 business days and notify you within two business days of doing so.9eCFR. Regulation E Section 205.11 – Procedures for Resolving Errors For new accounts (within 30 days of the first deposit), those timelines stretch to 20 and 90 days.
What the Third-Party Provider Sees
Approving a Pay by Bank transaction gives the third-party provider limited access to your bank data. Under the CFPB’s Personal Financial Data Rights rule (Section 1033 of the Dodd-Frank Act), that access comes with rules:
- The provider can only collect, use, and retain data to the extent reasonably necessary to deliver what you asked for. Using your data for targeted advertising, cross-selling, or resale is prohibited.10Federal Register. Required Rulemaking on Personal Financial Data Rights
- Authorization expires after one year unless you reauthorize.11eCFR. Part 1033 Personal Financial Data Rights
- You can revoke access at any time, and your bank must give you a reasonable way to do it.11eCFR. Part 1033 Personal Financial Data Rights
- Your bank cannot charge you or the provider for the data connection.11eCFR. Part 1033 Personal Financial Data Rights
Before any sharing starts, the provider has to show you a clear disclosure of what it will access and why, and you have to agree.11eCFR. Part 1033 Personal Financial Data Rights Enforcement of the rule is currently enjoined by a federal court pending CFPB reconsideration, so the timing of full implementation is uncertain.
Why You’re Seeing This Option
Merchants are pushing Pay by Bank because it costs them less. Card processing typically runs 1.5 to 3 percent per transaction, driven mostly by interchange fees. Pay by Bank rides ACH or instant rails that charge flat per-transaction fees, and industry estimates put merchant savings at 40 to 85 percent versus card acceptance, though the real number depends on volume, transaction size, and the provider’s pricing. It’s why the option shows up most often for large payments like rent, tuition, and utilities, where the percentage savings on a card fee are meaningful.1Board of Governors of the Federal Reserve System. Pay-by-Bank and the Merchant Payments Use Case For you, the tradeoff is different: convenience and no card number to enter, in exchange for weaker dispute rights and money that has already left your account.
