The app helps merchants view invoice activity, send secure payment links, review transaction history, and access supported in-person payment tools based on their merchant account and payment provider configuration. With AuxPAY, approved merchants can manage common payment tasks from one mobile dashboard, including payment links, invoices, receipts, transaction status, refunds, and voids where supported. Contactless payment acceptance, including Tap to Pay on iPhone where available, is enabled through supported third-party payment provider integrations and depends on merchant approval, device eligibility, regional availability, processor support, and provider configuration.
