Pay by bank is a payment method that lets customers pay for goods or services directly from their bank accounts. It’s becoming increasingly popular because of its security and lower transaction fees compared with those of traditional card-based payments. Transactions are typically processed quickly, sometimes instantly, depending on the banking infrastructure, and authentication methods such as bank login or multifactor authentication (MFA) ensure secure transactions.

Below, we’ll cover how pay by bank works, its benefits and challenges, and how this payment method is affecting the financial industry.

How does pay by bank work?

Pay by bank can be implemented through various technologies and platforms including open banking, bank application programming interfaces (APIs), or dedicated payment gateways that support direct bank transfers. It’s commonly used in ecommerce, bill payments, and other online transactions. For a customer to pay by bank, their bank typically needs to authenticate their identity and get payment confirmation before sending the funds. Here’s how it works:

  • Payment initiation: The customer chooses “pay by bank” or “bank transfer” as the payment method when purchasing a product or service. This option is typically available on ecommerce websites, bill payment portals, or other platforms that accept online payments.

  • Bank selection: The customer selects their bank from a list of supported banks. This is often presented in a dropdown menu or search function.

  • Customer authentication: The customer is redirected to their bank’s secure online portal or prompted to log in through a third-party interface. The customer might also have to provide additional authorization for the transaction such as a code sent to a mobile device, a security token, or biometric authentication (e.g., fingerprint or facial recognition). This step verifies the customer’s identity and authorizes the transaction.

  • Payment confirmation: The customer confirms payment details including the amount, recipient (business), and other relevant information.

  • Funds transfer: After confirmation, the bank processes the payment by transferring funds from the customer’s account to the business’s account.

  • Notification and completion: The customer and the business receive a notification confirming the successful payment. This confirmation might be in the form of an email, SMS, or on-screen message.

  • Settlement: The bank settles the transaction by updating the accounts involved.

Advantages of paying by bank over credit cards

Pay by bank offers some advantages over paying by credit card, which are outlined below.

Lower transaction costs

  • Lower fees: Bank transfers typically incur lower transaction fees compared with those of credit card payments. Payment processors charge businesses a percentage of the transaction value for credit card payments, which can be substantial. With direct bank payments, the fees are typically lower, benefiting businesses and customers.

  • Elimination of intermediaries: By directly transferring funds from the customer’s bank account to the business’s account, the need for third-party intermediaries is reduced, which leads to fewer payment processing fees and no interchange fees.

Better security

  • Direct authentication: When paying by bank, customers authenticate directly with their bank, reducing the risk of phishing and unauthorized access. This process typically involves MFA.

  • Fewer opportunities for fraud: Because bank transfers are often carried out in a bank’s secure online portal or mobile app, there are fewer opportunities for fraudulent actors to steal customers’ payment information.

Faster transactions

  • Real-time payments: Some bank-based payment methods can perform instant transactions. Though credit card payments are authorized in real time, businesses don’t usually receive the money instantaneously.

  • Faster settlements: Direct bank transfers can settle faster compared with credit card settlements, which often take a few days because of batch processing and reconciliation.

Increased customer control

  • Account-based payments: Customers can pay directly from their bank accounts without relying on credit limits or worrying about interest rates on outstanding balances.

  • No need for credit checks: Bank-based payments don’t require credit checks, making them accessible to those without credit or with poor credit history.

Lower risk of chargebacks

  • Reduced chargebacks: Credit card payments are prone to chargebacks because of disputes or fraudulent transactions. Direct bank payments typically have lower chargeback risks because of the secure authentication process and the reduced risk of unauthorized transactions.

  • Simplified dispute resolution: Because the transaction is between the customer and their bank, resolving disputes can be more straightforward, reducing the administrative burden on businesses.


  • Cross-border compatibility: Many bank-based payment systems are designed to work across borders, providing an easier international payment experience. Credit cards might have limitations because of varying acceptance rates and additional fees for international transactions.

  • Inclusion for unbanked and underbanked: Some bank-based systems offer access to individuals who might not have credit cards but do have bank accounts, promoting financial inclusion.

Pay by bank challenges

As with any payment method, pay by bank can present challenges for businesses. Here are some of the potential challenges:

User experience

The process of logging into a bank account, authenticating, and completing a transaction can be more complex and time-consuming than card-based payments. This additional friction might deter customers from using pay by bank.

  • Solution: Use technologies such as open banking and API integration to simplify the user interface and reduce the steps required to complete a transaction. Single sign-on (SSO) and consistent user flows across platforms can also improve the experience.

Transaction reversibility and chargebacks

Unlike credit card payments, bank transfers are typically irreversible, which can pose a problem for customers needing to reverse a transaction or address disputes.

  • Solution: Implement clear dispute resolution processes and customer support mechanisms. Offer refunds or adjustments in case of errors or customer dissatisfaction.

Security risks

Though bank-based payments are typically secure, they are not immune to security risks such as phishing or identity theft. Customers could be tricked into providing their bank credentials to malicious actors.

  • Solution: Educate users about security best practices and the risks of phishing. Use MFA, biometric verification, and secure communication protocols to boost security. Regularly perform security audits of payments platforms to identify and address vulnerabilities.

Cross-border compatibility

Bank-based payment methods can encounter compatibility issues when dealing with international transactions. Different banking systems and regulations in various countries can cause delays or additional fees.

  • Solution: Collaborate with banks and financial institutions to standardize cross-border payment processes. Use international payment gateways with experience handling cross-border transactions.

Dependence on banking infrastructure

Pay by bank relies on banking infrastructure, which might experience outages or downtime and lead to payment delays or failures.

  • Solution: Implement redundancy and failover systems to ensure continuity during outages. Work with banks that have reliable infrastructure and backup systems. Providing clear communication to customers during outages can also help manage expectations.

Compliance and regulation

Bank-based payments must comply with various regulations such as Anti-Money Laundering (AML) and Know Your Customer (KYC) rules. Compliance can add complexity and overhead to the payment process.

  • Solution: Stay informed about regulatory requirements, and keep all processes compliant with relevant laws. Work with legal experts and compliance officers to maintain adherence to regulations.

The evolving landscape of pay by bank

The pay by bank landscape is adapting to technological advancements, changing consumer preferences and regulations, and emerging partnerships and use cases.

Technological advancements

  • Open banking: Open banking initiatives, which let third-party developers build applications that connect to bank data through secure APIs, have increased pay by bank’s accessibility and interoperability among financial institutions.

  • Artificial intelligence (AI) and machine learning (ML): AI and ML are being used to improve fraud detection, security, and personalization in bank-based payments.

Regulatory changes

  • PSD2 and other regulations: The Payment Services Directive 2 (PSD2) in Europe requires banks to open their data to third parties (with customer consent), facilitating open banking and leading to increased competition and innovation in the payment industry.

  • Compliance and security: Regulatory frameworks have adapted to focus more on data protection and security, with stricter rules for financial transactions.

  • Convenience and speed: Customers increasingly expect easy and quick payment experiences.

  • Subscription services: Subscription-based businesses are increasingly adopting pay by bank as a recurring payment option. This model reduces reliance on credit card processing and associated fees.

  • Cross-border payments: Cross-border pay by bank solutions are growing in popularity, giving global businesses a lower-cost, faster option for transactions.
