## Debit Processor Migration Costs
A debit processor migration can look successful on a project plan and still create problems at the checkout counter.
## Hidden Costs Beyond Processor Fees
The report finds that outdated debit infrastructure can create costs well beyond processor fees, including false declines, manual exception work, fraud losses and slower product launches.
## Wallet Tokens Need Migration Plan
Customers using Apple Pay or Google Wallet expect their debit cards to keep working regardless of what happens behind the scenes.
## Smaller Cohorts Expose Trouble Early
The report recommends starting with lower-risk accounts, then moving into higher-usage, wallet-heavy and dispute-prone customer groups before broad conversion.
## Conversion Isn’t the Finish Line
Banks still need to watch authorization rates, false declines, fraud losses, exception volumes, complaints and wallet-token health.
## Real Cost of 0.50 Percentage Point
A modeled portfolio with 10 million monthly debit attempts and 0.50 percentage points of avoidable false declines would lose 50,000 good transactions.
## Key takeaway

A 0.50 percentage point reduction in false declines saves 50,000 monthly transactions for institutions with 10 million debit attempts.
