Debit Only for Real Money Gaming (RMG)

Overview

This feature enables merchants supporting Real Money Gaming (RMG) to
present only eligible debit cards during Paze Checkout. The merchant
passes useCase="RMG" and Paze evaluates wallet credentials so only
eligible debit cards are selectable while ineligible cards remain
visible but disabled.

Key Benefits

• Supports regulated debit-only checkout.
