Card platform modernization has moved from a technology conversation to a board-level priority for financial institutions (FIs) globally. Technical debt has piled up to the point where it constrains product development, limits scalability, and puts FIs at a disadvantage against more agile competitors. Datos Insights surveyed 220 card issuers, merchant acquirers, and other payment service providers (PSPs) across five markets, supplemented with interviews with 27 payment executives, to understand what is driving this shift and what stands in the way.
High-Volume Processors Face The Strongest Pressure to Modernize
Most respondents (74%) rate card platform modernization as a high or top priority over the next one to two years, and only 5% rate it low priority or no priority at all. The pressure to modernize is strongest for high-volume processors: 26% of firms processing more than one billion transactions annually rate modernization as a top priority, compared with just 9% of firms processing fewer than 200 million transactions.
Speed to market is the leading driver, cited by 66% of respondents. As customers grow less loyal to their primary institution, the ability to launch new products and features faster than competitors carries both growth opportunity and attrition risk. Scalability of payment processing follows at 48%, with operational resilience and cost reduction also cited as motivating factors.
Many FIs are actively considering replacing their legacy platform or processor. Seventy-one percent expect to evaluate new card payment processing vendors within six to 24 months, and they anticipate migrations taking 18 to 36 months, followed by eight to 10 years running the new platform. This is decade-long infrastructure planning, not a short-term procurement cycle.
Cost Predictability Is Important
Vendor pricing is not the pain point triggering migration that one might expect. More than three-quarters of organizations consider their current vendor pricing at least in line with the market, and just 22% call it somewhat or very expensive. Mexico is the exception; half of organizations view their vendor as at least somewhat expensive.
FIs want predictability. Fifty-nine percent rate cost predictability as extremely important, and 56% say the same of clear invoice reconciliation.
“Invoice reconciliation requires a doctorate in rocket science. The bank built its own Excel spreadsheet to decode vendor billing codes and terminology. Paying for line items for 10 to 15 years without fully understanding what they covered, simply because the invoice lacked clarity,” according to the Head of Commercial Cards at a U.S. issuer. FIs want to know what they will pay, understand what each line item covers, and see pricing that scales with consumption. That is the bar vendors need to clear.
Migration Risk Is The Real Barrier
If the appetite to modernize is so strong, why do so many FIs stay with incumbent vendors? Three-quarters of organizations cite the risk of service disruption as their greatest concern, well ahead of total project cost (50%) and time to complete (27%). Card processing runs in real time, and errors have immediate consequences for customers. That risk keeps institutions tied to platforms they know no longer serve them well. Even when banks evaluate alternatives, they often renew with an incumbent because of the complexity and cost of switching.
Methodology Belongs At The Centre Of Vendor Selection
This is why migration methodology belongs at the center of vendor selection. Eighty-seven percent of organizations rate the ability to migrate gradually as extremely or very important. Institutions expect vendors to run new and legacy platforms in parallel so they can fall back on existing infrastructure if problems surface.
Because the decision will govern operations for the better part of a decade, institutions scrutinize vendor credibility as closely as vendor capability. Companies specifically call out unrealistic promises as a trust-breaker: Once a vendor oversells what a migration can deliver, or how fast, the relationship will suffer, even when the underlying technology is sound.
The propensity to switch also depends on the processing model an FI already runs. Most U.S. FIs outsource their payment operations entirely to a third-party processor, paying per transaction, per account, or under a license-and-maintenance arrangement. These FIs face an added hurdle: They lack the in-house expertise to operate a platform themselves.
Outside the U.S., FIs more often build or license a platform to run themselves, either on premises or in the cloud. This makes it a different buying decision for these organizations: evaluating a platform to own and operate, not a service to consume.
Cloud-Native Is The Direction, Not Yet The Destination
Cloud strategy has moved from a technology decision to a commercial one. Across all markets, FIs no longer debate whether to move to the cloud but rather whether to invest in a cloud-native platform. However, the distinction between cloud-native and cloud-hosted is poorly understood and rarely verified. Institutions have experienced vendor overclaiming. Cloud-native claims must be substantiated through architectural evidence and independent references.
“Cloud-native must translate to tangible outcomes: faster onboarding, lower latency, better resilience, faster feature delivery. A platform merely cloud hosted on virtual machines provides no architectural advantage over on premises,” a VP of Product at a U.S. PSP commented.
Globally, 55% of institutions run hybrid architectures, and 22% are actively transitioning, with just 17% on modern cloud-native platforms and 5% still on legacy monolithic systems.
The gap by respondent type is starker still: 45% of PSPs already run modern cloud-native platforms, compared with just 9% of issuing banks and 11% of
acquiring banks.
PSPs were built on greenfield technology without inherited legacy infrastructure, and that advantage compounds as they deploy features, scale, and onboard clients faster than bank competitors.
An Early Start Is Key To Building A Clear Business Case
FIs should start evaluating card platform modernization now: Starting early gives FIs the time to assess vendors properly, complete due diligence, and build a clear business case for migration without putting the existing operation under unnecessary pressure. To mitigate the risk of service disruption during migration, the ability to migrate gradually, workload by workload, is essential. FIs should therefore score the vendor’s migration approach as a key factor in the RFP alongside product and functional capabilities.
The ability to run existing and new platforms in parallel can significantly reduce the risk of disruption and should give FIs more confidence to move away from an incumbent when the platform no longer meets their needs.
Cloud-native capability belongs in the selection criteria rather than being treated as an optional feature and should be judged on outcomes such as faster feature releases, lower latency, stronger resilience, and modern APIs, rather than on how a vendor describes its architecture.
