In today’s competitive market, brands are under pressure to prove loyalty ROI and meet rising consumer expectations for seamless, personalized rewards. The good news? There’s a smarter way to do it without building a full loyalty platform from scratch.
It’s called card linking, and it’s quickly becoming a mainstream strategy for customer engagement and growth.
Card linking connects a customer’s payment card directly to rewards, offers, or cashback. When a user links their debit or credit card to a loyalty or rewards program, any qualifying purchase automatically earns them value — no codes, coupons, or check-ins required.
Here’s how it works in practice:
For brands, this means fewer barriers to engagement. For users, it means a reward experience that just works.
Card linking has evolved from a niche financial technology into a core pillar of loyalty and engagement.
It first gained traction with banks and fintechs that wanted to connect transaction data with rewards. But as digital-first experiences became the norm, other industries – retail, dining, travel, wellness – followed.
According to a report from PYMNTS Intelligence and Banyan, card-linked offers are now used by millions of consumers globally, with 93% of users returning to redeem again.
In short, card linking has become mainstream because it’s the rare innovation that’s both frictionless and measurable.
Card linking is transforming how businesses engage customers, one transaction at a time. Here’s why:
Simplicity and convenience
Consumers don’t need to scan, upload, or remember anything. Once a card is linked, every qualifying purchase earns a reward automatically. This simplicity removes friction and drives repeat engagement.
Real-time rewards
With card linking, rewards are triggered the moment a transaction clears. That instant gratification reinforces loyalty and keeps customers active within your program.
Personalization and relevance
Because rewards can be tied to spending habits, each experience feels personal. Roundups, cashback, or micro-savings can align with user goals — from paying down debt to donating to a cause. That makes card-linked loyalty not just engaging, but meaningful.
Picture this: A customer buys coffee with their linked card. Instantly, they earn 5% cashback or a $0.50 roundup toward savings. No app open, no barcode scanned.
Behind the scenes, Olive’s infrastructure matches that transaction to an active offer and applies the correct reward automatically.
