Synapse Flux

MDB ↔ JPSTD Converter for Seamless Vending Integration

Synapse Flux is Payrallel’s intelligent protocol conversion module that bridges the gap between Japanese-standard vending machines (JPSTD / VCCS) and modern MDB L3 cashless payment devices.

Designed for real-world deployment, it enables operators to upgrade legacy or Japan-origin machines into fully cashless-enabled systems—without replacing the machine.

Bridge Two Worlds: JPSTD ↔ MDB

Many vending machines—especially those built for the Japanese market—operate on JPSTD (Japanese Protocol / VCCS), while most modern payment devices rely on MDB (Multi-Drop Bus).

Synapse Flux solves this incompatibility instantly.

  • Acts as a JPSTD Card Reader to the vending machine
  • Simulates an MDB Host to the MDB L3 payment terminal
  • Performs real-time signal translation between both protocols

This allows MDB L3 card readers to function seamlessly on machines that were never designed to support them.

How It Works

Synapse Flux sits between the vending machine and the payment terminal:

  • Converts JPSTD commands → MDB signals
  • Converts MDB responses → JPSTD-compatible signals
  • Maintains transaction integrity and timing requirements across both systems

The result is a fully transparent integration, with no changes required on either side.

Key Capabilities

✅ JPSTD (VCCS / Fuji Protocol) Support

✅ MDB L1 / L2 / L3 Compatibility

✅ Bi-directional Protocol Conversion Engine

✅ Low-latency Signal Processing

✅ Plug-and-play deployment with minimal configuration

Unlock Cashless for Japanese Machines

With Synapse Flux, operators can:

  • Enable card payments, QR payments, and digital wallets
  • Integrate with Payrallel-enabled cashless terminals, or any acquirer’s terminals which supports MDB L3
  • Extend the lifespan of existing vending assets
  • Avoid costly machine replacement or redesign

Ideal Use Cases

  • Japanese-import vending machines (Fuji / VCCS-based)
  • Mixed-fleet vending environments (MDB + JPSTD)
  • Retrofitting legacy machines to support cashless
  • Cross-border deployments in Southeast Asia
