What is Pay by Bank? A complete guide for businesses

Pay by Bank is an Open Banking-powered bank payment method. It allows customers to make an account-to-account payment without a debit or credit card. It means faster, smoother, and more secure payments.

This payment method is becoming increasingly popular in the UK and the European Union. The simplicity and security of this easy payment process have led to many businesses replacing cards with Pay by Bank among their main payment solutions.

What is Pay by Bank?

This payment method allows customers to pay a business directly by sending digital payments from their bank account to the merchant’s account. There is no need to use a debit or credit card, as open banking technology is used to send the money from the customer’s bank to the merchant.

It can provide near-instant payments and reduce fraudulent transactions by using open banking infrastructure and APIs. Strong Customer Authentication (SCA) is used to make this method highly secure. It helps significantly reduce fraud.

What is Pay by Bank method authentication, and how does it boost security? Multi-factor authentication by the customer’s bank may include a PIN, biometric authentication, or other bank credentials. It makes it more secure than many other payment methods. Customers just use the authentication they’ve set up on their bank account.

The direct nature of the real-time payment Pay by Bank offers is a key aspect. With no need for a credit or debit card and with no card scheme intermediaries involved in the payment flow, this is a smooth payment experience. For the merchant, the lack of a manual entry also makes it easier to process customer data.

The money can be transferred directly from their bank, often instantly when supported by instant payment schemes. The SEPA Instant Credit Transfer (SCT Inst) process is increasingly used, enabling real-time payments that operate 24/7 between participating banks. Unlike card payments, there is no standard card chargeback process, although refunds and returns can still be handled separately.

How does Pay by Bank work?

“What is Pay by Bank and how it works” are the next questions we need to cover. To better understand how the Pay by Bank payment method works, we need to look at the step-by-step process of sending money from a customer account to the merchant. 

Customer payment initiation

At the checkout, the customer chooses the Pay by Bank option from the list of alternative payment methods. In some cases, it might be listed as a bank transfer or open banking payment. 

With merchants increasingly adopting Pay by Bank checkout options, it’s now a more common option alongside credit card payments and other traditional methods. With an integrated API, the customer clicks on the merchant site to get taken securely to their banking platform.

Authentication by the customer

The next step sees the customer authentication process carried out. It is where they enter their online banking credentials for strong authentication and robust security measures. It only takes a moment, but it is a vital element of the secure process.   

It’s this process that ensures this is among the most secure payment methods. The authentication methods are those set up on the payer’s bank account to confirm financial transactions.

Payment is sent instantly

The instant bank transfer process is used to send the money directly from their bank account to the merchant. No sensitive data is included, and the payment experience is slick for the customer and merchant.  

The merchant receives instant confirmation

The final step in the Pay by Bank process sees the merchant receive confirmation of the successful payment. With no debit cards involved, there is no need for the payment to go through the card network.

This simple account-to-account method makes it one of the safest payment options. In terms of fraud prevention, Pay by Bank lowers the risk of fraudulent transactions.
