Understand bank payments. Build better experiences.
Practical explanations of Open Banking, Pay by Bank and account-to-account payments for businesses building the next generation of payment experiences.
Whether you're exploring Pay by Bank for the first time or thinking about how it could fit into your existing payment infrastructure, Wetapo Guides are designed to make the important concepts easier to understand.
Modern bank payments bring together several different technologies and concepts.
Understanding how they fit together makes it easier to evaluate where Pay by Bank belongs within your business.
What is Open Banking?
Open Banking enables customers to use regulated services that interact with their bank accounts with their consent.
In payments, this creates opportunities to build experiences where customers can authenticate with their bank and authorise a payment directly from their bank account.
What is Pay by Bank?
Pay by Bank is a payment experience that allows a customer to choose their bank, authenticate and authorise a payment through their banking environment. Instead of entering card details, the customer uses their existing bank account to complete the payment.
What are A2A payments?
Account-to-account, or A2A, payments move money between bank accounts. Open Banking can provide the technology needed to initiate these payments through digital checkout and application experiences.
From concept to customer experience
Understanding the technology is only part of the picture.
For businesses, the more important question is how bank payments fit into the customer journey.
A typical Pay by Bank experience begins when the customer chooses bank payment as their payment method. The customer selects their bank, securely authenticates and authorises the payment.
The business can then use payment status information to determine what happens next — whether that's continuing an order, updating a transaction or moving the customer to another stage of the product experience.
