Acquiring · Issuing · Switching

One platform. Every payment.

momentPay builds the processing core that banks, processors, PSPs and fintechs run their card businesses on — merchant acquiring, card issuing, and the real-time switch that connects both to the networks.

The platform

Seven products, one connected platform

From the billing counter to the general ledger — capture, switching, issuing, acquiring, risk and reconciliation are built as one system, so you deploy the parts you need without carrying the operational weight of the parts you do not.

momentPay Orchestrate

Sends the payment request, accepts it on every digital channel and routes it through the aggregator that clears it best — payment links, e-commerce, apps and marketplaces on one platform.

Architecture

Both sides of the transaction, on the same engine

Every card transaction has an acquirer standing behind the merchant and an issuer standing behind the cardholder. Conventional estates run those as separate platforms with separate integrations. momentPay runs them as mirror roles on one protocol engine.

  • Acquiring takes a transaction from a terminal or checkout page, works out which network owns the card, and dispatches it in that network's exact wire format.
  • Issuing does the mirror job: it receives a transaction the network is routing to the issuer and hands it to an authorization decision service.
  • Shared core handles routing, message translation and persistence for both directions, so a new scheme is a configuration exercise rather than a rebuild.

Why momentPay

Engineered for institutions that cannot go down

Multi-protocol native

ISO 8583 card processing and UPI/QR digital payments run as first-class workloads on one platform, not as a bolt-on module bridged to a second system.

Actor-model concurrency

Built on Elixir and the OTP runtime. Each connection and transaction runs as an isolated, supervised process, so a single failure is contained and recovered automatically.

Fail closed, reverse on ambiguity

A transaction is written to durable storage before it is dispatched. A timeout is treated differently from a decline, and triggers an automatic reversal rather than an assumption.

Hardware-protected keys

PIN blocks and cryptographic keys are handled through a hardware security module, never held in application memory in the clear.

Configuration, not rebuilds

A network's connection details, routing rules and message format are data rather than code. Extending coverage never touches another network's path.

Scales without re-architecture

Additional nodes join the cluster and load-balance automatically, so growth in transaction volume is an infrastructure change rather than an architectural one.

Network connectivity

Connected to the networks your business depends on

Each network is reached through whichever interface the relationship requires — a direct ISO 8583 connection over TCP, or a direct-to-scheme REST API secured with mutual TLS. Both run through the same protocol engine.

Status reflects online authorization coverage. Every network added follows the same pattern: a routing rule plus a message translator.
