Fintech Software Challenges We Solve
Regulatory pressure, legacy infrastructure, and rising customer expectations are straining fintech and banking teams
Heavy Regulatory Complexity
PCI-DSS, SOX, and AML/KYC obligations touch nearly every feature, turning routine changes into compliance projects.
Legacy Core Banking Systems
Aging core banking and financial platforms are expensive and risky to change, slowing innovation to a crawl.
Fraud & Security Risk at Scale
Every new payment rail or integration expands the attack surface for fraud, account takeover, and data theft.
Slow, Friction-Heavy Onboarding
Manual KYC checks and clunky verification flows drive applicant drop-off before an account is ever opened.
Scalability Under Transaction Spikes
Trading windows, payroll cycles, and market volatility create transaction spikes that legacy systems cannot absorb.
UX Gaps Driving Customer Churn
Outdated digital experiences push customers toward fintech-native competitors with faster, simpler apps.

Accessible, Inclusive Banking Experiences
As a WCAG and ADA compliance specialist, D2i Technology builds banking and payment applications to WCAG 2.1/2.2 AA from the ground up – covering accessible account statements and disclosures, screen-reader-friendly transaction tables, and keyboard-operable payment and transfer flows – then verifies them with manual assistive-technology testing, not just automated scans.
What we build in
- WCAG 2.1 / 2.2 AA conformance
- Keyboard-operable payment flows
- Screen-reader-friendly transaction tables
- Accessible statements & disclosures
Why Accessibility Matters in Fintech
- Customers with disabilities need independent access to their accounts, statements, and payment tools - not assistance from someone else.
- Banking and fintech is one of the most litigated sectors for ADA web-accessibility claims, with lawsuits targeting banks and fintechs every year.
- Regulators in many jurisdictions expect financial services to be accessible to all customers, regardless of ability.
- Accessible design also improves usability for older customers and anyone using a low-bandwidth or assistive device.
