Open Banking Rules Are Reshaping Payment Apps

Open banking requires banks to let customers share account data and initiate payments through authorised third parties, using standard interfaces and explicit consent. The consumer-facing result is a wave of apps that can see across accounts and move money without touching a card network.

The two capabilities

Account information access lets an authorised app read balances and transactions across your institutions. This is what powers budgeting tools, aggregated dashboards and lenders that verify income from actual cash flow rather than payslips.

Payment initiation lets an app instruct a payment directly from your bank account. Combined with instant payment rails, this settles in seconds at a fraction of card interchange cost.

Why merchants are pushing it

Card acceptance costs a merchant a percentage of every sale. Account-to-account payment costs a small flat fee. On low-margin, high-volume categories the difference is decisive, which is why merchants are actively promoting bank-payment options at checkout with discounts and loyalty incentives.

What consumers gain

• Consolidated view of accounts held at different institutions.
• Credit assessment based on real cash flow, useful for thin-file and self-employed applicants.
• Faster settlement — funds arrive in seconds rather than days.
• Easier switching, since transaction history can be shared with a new provider.

What consumers should watch

Chargeback rights. Card payments carry well-established dispute mechanisms. A bank transfer is a push payment, and recovering funds after a dispute or a scam is far harder. For high-value or higher-risk purchases, the card's protection is worth its cost.

Consent management. Access is granted for a period and must be renewed, but people accumulate consents and forget them. Review connected applications in your banking app periodically and revoke what you no longer use.

Data scope. Sharing transaction history reveals a detailed picture of your life. Check what an app requests, what it retains after you disconnect, and whether it sells derived insights.

Authorisation status. Only regulated, authorised providers may access accounts. Verify a provider appears on the relevant public register before connecting.

Where this is heading

Regulators are extending the model beyond payments toward broader open finance — pensions, insurance, investments — and adding variable recurring payments, which allow a merchant to pull differing amounts within limits you set. That last feature is the credible direct-debit replacement and the main battleground with card networks over the next few years.

Practical takeaways

• Account-to-account payments are cheaper and faster but weaker on dispute rights.
• Review and revoke stale data-sharing consents at least once a year.
• Confirm any provider is authorised before granting access.
