Authorization Optimization

Decline prevention

Credentials are updated in real time for recurring transactions, which keeps payments up to date and prevents declines.

Decline recovery

Implement dynamic decisioning to recoup declines, powered by transaction, network and consumer behavior data, all while taking issuer-specific rules into account.

Routing Optimization

Reduce network cost

The global reach of our network relationships, including ownership of STAR and Accel, provides you with choice to route transactions at the­ lowest cost.

Reduce interchange cost

Network token service will lower interchange for certain card-not-present credit transactions processed using a Visa® EMV Payment Token.

Fraud Mitigation

Reduce risk

Block fraudulent transactions and avoid reputation damage. Our merchants experience reductions in decline rates, chargeback rates, required resources and overall costs.

Protect customers and build brand loyalty

Customers will experience a frictionless payment experience, while their information is protected ­ from fraud.
