Moving off a legacy processor isn't the goal. Building on modern infrastructure is. NymCard helps banks modernize their payments stack and move onto nCore without disrupting the programs customers rely on today.
The hard part isn't seeing the problem. It's getting from where you are today to where you need to be tomorrow.
Years of cardholder data, complex integrations, operational risk, and customer impact make migration one of the hardest decisions a bank can make. So many banks keep running infrastructure they have already outgrown.
Most platforms treat migration as a one-time project. NymCard treats it as part of the platform.
nCore is built for migration
Migration runs natively inside nCore. Portfolios can move in phases, run in parallel, and follow the approach that fits your business. Existing cards can stay active throughout the transition, or be re-issued as part of a broader transformation program.

Agentic AI does the heavy lifting
AI agents handle mapping, testing, reconciliation, and cutover planning alongside your team. Work that used to take months of engineering becomes automated, reviewable, and controlled.

Automate the work, keep the control.
AI agents do the heavy, error-prone work of migration. Your team stays in control of every step.
Automated mapping
Agents read legacy schemas and map cardholder data, BIN ranges, tokens, and operational data into nCore.
Parallel processing and automated reconciliation keep balances, positions, and transactions aligned throughout the migration.

Migration gets you onto the platform. The platform changes what you can build.
Most migrations end with a new processor.
A migration to nCore puts cards, lending, money movement, settlement, financial crime, and reconciliation on one architecture, with a 360° customer view, one data layer, and AI built directly into the core.
Modernization doesn't end when the migration finishes. It starts there.
