How to Design a Co-Brand Debit Card Customers Will Use Every Day

By Paul Dunning

Launch a debit card to create a new growth engine that increases share of wallet and drives direct bookings

Key Takeaways

• Co-branded debit cards keep your brand in customers’ hands 365 days a year—not just during trips

• 90% of U.S. adults have a debit card, representing a massive untapped loyalty opportunity

• Daily card usage drives direct bookings, reduces OTA dependence, and increases customer lifetime value

• Co-branded debit is one of the most accessible ancillary revenue streams available to travel and hospitality brands

• Modern platforms can launch programs in months, not years

I’ve seen the rules of customer engagement fundamentally change for travel and hospitality brands. Loyalty programs that once guaranteed repeat bookings now compete against third-party platforms, digital wallets, and aggregators that insert themselves between your brand and your customer.

The result: eroding margins, diminishing data visibility, and growing distance from the travelers you’ve spent years cultivating.

In my experience working with travel and hospitality brands, the companies pulling ahead recognize a counterintuitive truth: the most powerful loyalty tool isn’t the one customers use twice a year for flights or hotel stays—it’s the one they reach for every day.

That tool is a co-branded debit card designed as a daily payment instrument that keeps your brand present in customers’ lives 365 days a year.

Why revenue growth depends on owning the payment relationship

The economics are straightforward: you can’t grow share of wallet if you’re not part of everyday spend.

Traditional co-branded credit cards reach only a fraction of your customer base. Consider:

• 90% of U.S. consumers own a debit card, according to the U.S. Federal Reserve

• That means many of your customers—including your most loyal—make daily purchases with payment instruments that have no connection to your brand

• Every off-brand transaction is a missed opportunity for brand reinforcement

Third-party platforms have built business models around capturing customer relationships, redirecting travelers toward whichever brand offers the best margin for the platform.

A well-designed co-branded debit card reverses this equation by keeping your brand in customers’ hands, wallets, and minds every single day.

What’s the hidden cost of being “trip-only”

A card that customers use exclusively for bookings may sit idle for the vast majority of a given year. During those dormant months, competitors actively engage your customers with alternative offers.

The financial impact compounds quickly:

• Limited interchange revenue — infrequent usage means minimal ancillary fee income from merchant transactions

• Sparse transaction data — you’re blind to spending patterns that could inform personalization

• Eroding brand preference — competitors fill the gap between your bookings

• Missed ancillary revenue — every dormant period is a period where the card generates no value for your brand or your customer

How to reframe debit as a share-of-wallet strategy

Don’t think of debit as a downmarket alternative to credit. Instead, you may want to design it as a daily payment instrument that happens to deliver travel value—not the other way around.

This reframe changes everything about card design:

• Optimize for frequency, not large infrequent purchases

• Target the small, habitual transactions that occur dozens of times per month

• Build the behavioral loop: Frequency → Engagement → Preference → Bookings

I’ve consistently seen that customers who use a brand’s payment card for everyday purchases demonstrate significantly higher lifetime value. They book more frequently, spend more per trip, and show greater resistance to competitive offers.

Design for everyday spend that ladders back to travel

Target the spending categories where customers already transact most frequently:

• Dining and restaurants

• Groceries

• Transit and gas

• Subscriptions

• Everyday retail

The connection to travel value must be clear and compelling. Every coffee purchase, every grocery run, every tank of gas should visibly accumulate toward meaningful travel rewards—points toward a free night, miles toward an upgrade, or credits toward ancillary services.

The psychology is powerful: customers see daily spending building toward their next adventure, transforming routine transactions into progress toward something aspirational.

How to turn debit spend into direct booking behavior

For travel and hospitality brands, the ultimate objective isn’t card usage for its own sake. Rather, it’s directing customers back to your owned booking channels, reducing dependence on OTAs that extract margin and dilute relationships.

Card-linked incentives that drive direct bookings include:

• Bonus points for booking direct

• Exclusive rates available only to cardholders

• Priority access to inventory during peak periods

• Waived fees for bookings through your app

• Early check-in/late checkout privileges

The economics work because you’re trading margin you would have paid to intermediaries for loyalty you own permanently.

How co-branded debit unlocks ancillary revenue streams

For travel and hospitality brands, ancillary revenue—the income generated beyond core bookings—is one of the most strategic levers for sustainable growth. A co-branded debit card is one of the most effective tools available for driving ancillary revenue, because the card operates across every dimension of a customer's financial life, not just their travel spend.

A co-branded debit card is also a data asset—one that reveals far more about customer behavior than booking history alone.

Transaction data reveal:

• Where customers eat, shop, and spend leisure time

• Life events (home improvement surge = recent move; restaurant spike = celebration)

• Travel intent signals before customers start actively searching

Enable precision targeting:

• Frequent business travel patterns → airport lounge access offers

• Family spending indicators → kid-friendly destination promotions

• Increased dining activity → weekend getaway offers

Ancillary revenue opportunities this unlocks:

• Upsells to premium seat upgrades, room upgrades, and add-on services timed to spending signals

• Targeted promotions for travel insurance, car rental, and tours—offered when intent is highest

• Co-marketing partnerships with dining, retail, and lifestyle brands that pay to reach your cardholders

• Interchange revenue from every daily transaction, independent of booking cycles

Result: Better conversion rates, reduced marketing waste, and offers that feel relevant rather than random.

How to build digital-first experiences that reinforce brand preference

The following features are table stakes for modern co-branded debit:

• Mobile wallet provisioning — digital wallet integration from day one

• Real-time notifications — every purchase displays your logo and reward balance

• Unified app experience — check balance, review history, and book travel in one place

• Instant card issuance — digital-first activation, physical card follows

• Frictionless connection — spending, earning, and redeeming feel like one seamless journey

Every point of friction you remove translates directly to increased card activity. A card that’s easy to add to a digital wallet gets used more than one requiring physical plastic.

The economics that reward frequency

Debit program economics differ fundamentally from credit. Without interest income, debit depends on interchange revenue and downstream booking value.

The good news: debit economics favor exactly the behavior you want:

• Frequent transactions generate consistent, predictable interchange revenue

• A customer using your card 40 times/month generates more stable value than two large annual credit purchases

• Share of wallet stabilizes revenue beyond seasonal travel cycles

The math works when increased booking frequency and direct channel shift offset reward costs—which they typically do, often substantially. That's why the right platform partner should be willing to share in the investment. At Galileo, we have the capital and appetite to partner with brands through the initial acquisition curve—not just provide technology, but co-own the program's path to profitability.

Use debit as strategic defense against disintermediation

Beyond revenue growth, co-branded debit serves a defensive function: protecting customer relationships from intermediaries that control travel distribution.

How daily-use debit changes the competitive dynamic:

• Instead of fighting for attention only at booking time, you maintain continuous presence in customers’ lives

• When customers are ready to travel, your brand is already in their hand—not one option among many on a comparison site

• Booking becomes an extension of an existing relationship rather than a transactional decision

How to build a payment card program with custom branding

Building a co-branded debit card program means more than designing a card with your logo on it. It requires assembling the right technology infrastructure, program economics, and compliance framework—then ensuring all of it can scale as your customer base and product ambitions grow.

The starting point is custom branding: white-label platform flexibility gives your team full control over the card design, the in-app experience, the rewards structure, and how customers interact with your brand at every touchpoint. The card should feel like an extension of your loyalty ecosystem, not a generic financial product.

For growing businesses, the ability to implement a scalable debit solution without overbuilding from day one is equally critical. The right platform grows with you—handling increased transaction volume, expanded product features, and new markets without requiring an infrastructure rebuild.

I’ve seen many brands struggle because legacy card platforms can’t provide these capabilities.

Essential platform capabilities:

• Custom branding and white-label flexibility — full control over card design, app experience, and program economics

• Flexibility — design spend-based incentives tailored to your brand, not generic structures

• Digital-first architecture — instant provisioning, real-time notifications, seamless integrations

• Speed to market — months, not years (modern platforms like Galileo Financial Technologies have compressed timelines dramatically)

• Data access — visibility into transaction patterns for personalization and ancillary revenue development

• White-label flexibility — full control over customer experience and program economics

• Processor ownership — the strongest platforms act as both program manager and core processor. When your partner owns the underlying technology stack—rather than relying on a third-party processor—you gain faster product iteration, cleaner data access, and freedom from vendor lock-in if you ever need to migrate or change sponsor banks.

• Scalability — infrastructure that evolves with your strategy, from pilot to full program without rebuilding

For organizations under pressure to launch quickly without sacrificing long-term scalability, platform selection may be the most consequential decision in the entire initiative.

A related question worth addressing early: how much of the program's ongoing operations should your team manage in-house versus outsourcing to a partner? 

Program management—the day-to-day oversight of compliance workflows, settlement, fraud prevention, and ecosystem coordination—can be structured in multiple ways depending on your organization's scale, expertise, and strategic priorities. Understanding where you sit on that spectrum before you launch can save significant time and cost later.

The bottom line: from payment method to growth channel

Travel and hospitality brands that will lead the next decade recognize co-branded debit not as a product to offer, but as a growth channel to develop.

The card is the mechanism through which:

• Daily engagement translates into booking preference

• Share of wallet becomes share of bookings

• Customer relationships are protected from intermediary capture • Ancillary revenue streams are identified, activated, and scaled

The opportunity is substantial and the competitive window is open. While credit co-brands have long been contested territory, debit remains largely undeveloped in travel and hospitality. Brands that move decisively can establish positions that later entrants will struggle to challenge.

A well-designed co-branded debit card doesn’t just process payments. It brings customers back to book again and again, fostering powerful brand loyalty and driving long-term value.
