White-Label Payment Switch.
Own your card-present transaction flow. Multi-acquirer routing, automatic failover, and a complete operations dashboard — deployed in weeks, as SaaS or on-premise.
A payment switch you control, not one you rent.
Switch39 routes card-present transactions across multiple acquirers with smart routing, automatic failover, and zero-touch terminal provisioning — all under your brand.
Smart Multi-Acquirer Routing
Dynamic routing with cost optimization and failover. Round robin, weighted, and chained failover algorithms. Route by card type, BIN range, cost, or availability.
Zero-Touch Terminal Provisioning
Connect any terminal app via HTTP/JSON API. Optionally pair with CardPay39 for box-to-production deployment on Castles terminals — no manual setup per site.
Dashboard39 Integration
Real-time monitoring, merchant management, terminal fleet oversight, settlement views, and intelligent alerting — the full operations layer built in.
Simple HTTP/JSON API
Any terminal application can connect. New merchants onboarded in minutes. No ISO 8583 knowledge required on the POS side — we handle the legacy protocols.
Channels in. Acquirers out. You own the middle.
Switch39 sits between your channels and your acquirers, translating POS protocols and routing every transaction by your rules.
Add new acquirers without re-integration.
Shift4, Worldline, Amex, and Silverflow are ready out of the box. New acquirers are added through configuration, not code — via a plugin architecture that keeps your core untouched.
Your brand, your acquirers, your merchant relationships.
Your Branding Everywhere
Portals, receipts, and forms all carry your brand. Field39 stays invisible to your merchants.
No Lock-In
Choose your acquirers, devices, and channels. Switch them on your terms, not a vendor’s.
You Own the Relationship
Full control over merchant relationships and pricing. Your margin stays yours.
Fixed fee per transaction.
No basis points. No revenue share. No hidden costs. Predictable economics as you scale — contact sales for specifics tailored to your volume.
