Electronic funds transfer (EFT)
What is electronic funds transfer (EFT)?
Electronic funds transfer (EFT) is the movement of money between bank accounts over a computer network, with no paper instrument such as cash or a check involved. EFT is an umbrella category rather than a single payment rail: direct deposits, debits, wire transfers, direct debits, card payments, and ATM withdrawals all fall under it.
The term carries two meanings. In US consumer-protection law it is a defined category, governed by the Electronic Fund Transfer Act and its implementing rule, Regulation E (12 CFR Part 1005), which sets error-resolution and liability rules for consumer accounts. In payments operations it is shorthand for money that moved electronically, and the detail that decides everything downstream is which rail carried it, since each rail has its own clearing model, settlement timing, and reversibility.
Key facts
- Also known as: electronic payment, EFT payment, electronic transfer
- Covers: , wire transfers, , card transactions, transfers, ATM cash withdrawals
- Defined in US law by: the Electronic Fund Transfer Act, implemented through Regulation E (12 CFR Part 1005), covering consumer accounts
- Settlement speed: seconds on real-time rails, next business day or later on batch rails, depending on the rail and its cut-off times
- Applies to: consumers, merchants, employers running payroll, and the banks on both sides of the transfer
Types
- – batched bank-to-bank debits and credits used for payroll, bill pay, and recurring collections in the US
- – a mandate-based pull from the payer's account, run through Direct Debit in the euro area and equivalent schemes in other markets
- Wire transfers – individually processed credit transfers, routed for cross-border value over messaging networks such as
- Card payments – authorization and across a , the EFT type most e-commerce merchants handle daily
- – account-to-account credits that clear and settle within seconds, increasingly initiated through interfaces
- ATM transactions – balance transfers and at a terminal, debited straight from the cardholder's account
These categories are rails, so they overlap in practice: a single business commonly uses several at once, with cards at checkout, ACH for , and wires for treasury movements.
How it works
- Initiation – the payer authorizes the transfer through online banking, a checkout page, a card terminal, or a standing mandate. The instruction carries the payee's account details and the amount.
- Validation – the originating bank checks account details and available balance, then screens against sanctions lists and fraud rules.
- Routing – the instruction goes onto the rail the payment method belongs to: an ACH operator, a wire network, or a .
- Clearing – the rail exchanges the instruction between the two banks. Batch rails accumulate instructions and process them in cycles through , while wire and real-time rails pass each instruction on its own.
- Settlement – funds move between the banks' accounts, and the receiving bank posts the credit to the payee's account.
- – both sides match the posted entry back to the original instruction using the rail's reference identifiers, which turns a bank statement line into a closed transaction record.
Why it matters
- Reversibility is set by the rail, not by the amount. A card payment can be pulled back months later through a , an ACH debit can be returned within the scheme's return window, and a completed wire is final unless the beneficiary agrees to send it back.
- Timing decides working capital. A merchant paid over a batch rail carries the receivable until the settlement cycle closes, while a real-time credit is spendable on arrival.
- Cross-border EFT adds a conversion step. The applied at conversion, and whether is offered at the point of payment, changes what the payee actually receives.
- Account-to-account EFT doesn't run through card authorization logic, so a payment the declines can still complete on a bank rail. That's why merchants with high decline volumes add a bank transfer option next to cards.
