Open Banking Rewards: Turning Transaction Data Into Loyalty

For years, retailers have tried to build loyalty programmes on the back of incomplete data — a few clicks, a sign-up form, maybe a survey response. Open Banking changes that. With a customer's consent, brands can now see the full picture of how, where and how often someone really spends. And when that data is used responsibly, the loyalty programmes built on top of it become unrecognisably better.

This article looks at how Open Banking is reshaping rewards, why personalisation is finally living up to its promise, and how networks like The Reward Collection bring banks, fintechs and retailers together to make it all work.

What is Open Banking?

Open Banking is the UK regulatory framework — born out of PSD2 — that lets consumers securely share their bank account data with authorised third parties. The key word is consent: nothing happens without the customer explicitly opting in.

For loyalty, the relevant pieces are:

• Account information services (AIS) — read-only access to transaction history.
• Payment initiation services (PIS) — the ability to initiate bank-to-bank payments.

It is AIS that powers most modern Open Banking reward programmes today. Retailers and reward partners can see (with permission) what categories a customer spends in, which merchants they favour, and how their habits evolve over time.

Why transaction data beats survey data

Traditional segmentation relies on stated preferences. Open Banking relies on revealed behaviour — and the gap between the two is enormous.

A customer might say they shop sustainably. Their transactions reveal whether they actually do. They might claim to be loyal to a single supermarket. Their statements show a basket split across three. That truth is loyalty gold.

With Open Banking data, retailers and reward platforms can:

• Identify high-value customers who are about to lapse
• Spot category switchers — and intercept them with a relevant offer
• Build genuine lookalike audiences based on real spending behaviour
• Reward the customers who actually drive incremental revenue, not just the loud ones

Powering personalisation at scale

Open Banking lets reward programmes evolve from broadcast ("here's 10% off everything") to truly personalised ("here's an offer at the coffee chain you visit twice a week"). That precision is what modern customers expect — and what generic loyalty schemes still fail to deliver.

For brands, the operational shift looks like this:

1. Connect to an Open Banking provider through a CLO/loyalty network.
2. Segment customers based on observed spending patterns.
3. Trigger rewards that match each segment's actual habits.
4. Measure real change in behaviour — not just opens and clicks.

When this loop is in place, reward budgets stop being sprayed across uninterested audiences and start being deployed where they actually convert.

Combining Open Banking with Card-Linked Offers

Open Banking and Card-Linked Offers are stronger together. CLO provides the frictionless redemption mechanic. Open Banking provides the intelligence to know which offer should fire for which shopper.

That is the architecture The Reward Collection sits at the heart of — connecting 500+ merchants with bank-grade Open Banking infrastructure and a portfolio of reward partners. A single integration gives both sides of the equation the data and the rails they need.

Privacy, consent and trust

None of this works without consumer trust. The strongest Open Banking programmes treat data dignity as a feature, not a footnote:

• Explicit consent at every step, in plain language.
• Time-limited access that customers can revoke any time.
• Purpose limitation — data is used only for the agreed reward use case.
• Bank-grade encryption and access control across the stack.

Done well, Open Banking is one of the most privacy-respecting personalisation tools available. The customer is in charge — and they benefit directly from sharing.

What good Open Banking loyalty looks like

The brands getting this right share a few habits:

• They start with a clear customer benefit, not a data wishlist.
• They invest in onboarding flows that explain the value exchange.
• They reward sustained behaviour, not one-off transactions.
• They iterate constantly — segmenting, testing, refining the offer mix.

The retailers who treat Open Banking as a loyalty multiplier — rather than a marketing data play — are building the kind of programmes that customers actually want to be part of.

Where to start

If you are exploring Open Banking rewards for the first time, the easiest entry point is plugging into an existing network rather than building from scratch. That is exactly what The Reward Collection delivers for retailers and banking partners across the UK.
