Pay by Bank: The Future of Payments

What is Pay by Bank?

Pay by Bank is a fast and secure way for customers to pay directly from their bank account at checkout. Instead of entering card details, the customer selects their bank, approves the payment in their banking app, and the funds are transferred instantly. No card networks. No intermediaries. Just a direct, secure payment.

In the United Kingdom, Pay by Bank is powered by Open Banking and the Faster Payments network. Across Europe, it runs on SEPA/Instant SEPA, and similar systems are now emerging worldwide, including PIX in Brazil, UPI in India, and FedNow in the United States.

How Pay by Bank Works

• Customer selects Pay by Bank at checkout
• They choose their bank from a list
• They are redirected to their banking app with the payment details pre-filled
• The customer approves the payment using Strong Customer Authentication (SCA) through biometrics or secure login
• Funds are transferred directly to the merchant

No card numbers. No intermediaries. No risk of stolen details.

Why Merchants Should Care

For businesses, Pay by Bank is not just another payment option. It is a way to solve some of the biggest challenges in online commerce:

• Lower fees: no card networks or interchange costs.
• Instant settlement: funds land in your account usually within seconds, improving cash flow.
• Reduced fraud and no chargebacks in most markets: every payment is authenticated by the customer's own bank using Strong Customer Authentication (SCA).
• Higher conversion: customers already trust their bank, making them more likely to complete checkout.

Payment Rails Behind Pay by Bank Around the World

While the United Kingdom has led adoption, Pay by Bank is expanding rapidly across global markets:

• United Kingdom: Faster Payments.
• EU: SEPA and SEPA Instant payments.
• Brazil: PIX is now the dominant payment method.
• US: ACH, FedNow and RTP.
• Australia: New Payments Platform (NPP).
• India: UPI, processing billions of instant transactions each month.

Merchants everywhere are embracing Pay by Bank for its lower costs and stronger security. The challenge is that most of these systems are designed for domestic payments, and using them across borders remains fragmented and expensive.
