Eight engineering verticals · one accountable stack

Eight verticals, engineered and operated by one team — from device kernel to general ledger.

Each vertical is delivered and operated in-region by Xentra and engineered with our R&D headquarters in Kerala, so the team that commissions your system also answers for the code inside it. Filter by domain, then watch how each system behaves under load and under failure.

Payment Gateway & Acquiring Engineering

Switching and acquiring stacks built for authorisation paths where every millisecond and every basis point is audited.

  • End-to-end payment switches — ISO 8583 and ISO 20022 message handling from terminal and e-commerce ingress through to scheme and issuer endpoints.
  • Multi-currency acquiring engines with per-merchant pricing, FX handling and scheme-fee attribution on every transaction.
  • Smart transaction routing — least-cost, BIN-aware and health-weighted, with automatic failover when a rail degrades.
  • Automated split settlements and reconciliation engines — three-way matching of switch logs, scheme files and bank statements, with exception queues.
  • Tokenization vaults and 3DS2 authentication — PANs isolated from merchant systems; frictionless and challenge flows handled server-side.
  • EMV Level 1/2/3 kernel integrations — contact and contactless kernels integrated into terminals and supported through Level 3 test cycles.

Payment Aggregation Services & Merchant Ecosystems

Payment-facilitator infrastructure to onboard, ledger and pay out thousands of sub-merchants under a single programme.

  • White-label PayFac platforms — branded merchant portals, pricing plans and programme rules run under your licence and sponsor bank.
  • Automated KYC/KYB merchant onboarding — document capture, registry and sanctions checks, risk tiering and maker-checker approval in one workflow.
  • Sub-merchant ledgering — a double-entry ledger per sub-merchant for captures, fees, reserves, refunds and chargebacks.
  • Instant payout rails — T+0 and on-demand payouts governed by rolling-reserve and payout-limit controls.
  • Dynamic QR and POS unification — one merchant identity and one settlement report across QR, soft-POS, countertop and online checkout.
  • Multi-bank API orchestration — a single integration layer over several sponsor and payout banks, with balance-aware routing.

03 · Enterprise cores

Enterprise ERP & Financial Cores

Financial systems of record built on strict double-entry discipline — consistent under concurrency, auditable years later.

  • High-concurrency double-entry ledgers for core banking and finance — immutable journals, idempotent posting, balances that always reconcile to journal lines.
  • Automated treasury and bulk hedging integrations — cash positioning, sweep rules and FX hedge bookings exchanged with bank and treasury platforms.
  • Multi-entity tax and VAT compliance engines — GST and VAT determination, e-invoicing and return-ready reporting per legal entity.
  • Supply chain and inventory automation — procure-to-pay, stock valuation and warehouse movements posted straight to the ledger.
  • Real-time general ledger synchronisation — sub-ledgers, payment systems and the GL kept in step by event streams rather than nightly batches.

04 · AI & data

AI Fraud & Risk Intelligence

Decisioning that sits inline with authorisation, scoring every transaction before the issuer response window closes.

  • Sub-10 ms real-time transaction scoring — feature lookups and model inference served from memory, inside the authorisation path.
  • Behavioural biometrics — typing cadence, touch and device signals that separate genuine customers from scripted or remote-controlled sessions.
  • Velocity and graph-network anomaly detection — cards, devices, merchants and accounts linked to expose mule rings and collusive merchants.
  • Automated AML/KYC transaction screening and sanction list filtering — fuzzy name matching against sanctions and PEP lists with a full audit trail.
  • Adaptive rule engines — thresholds and rules retuned from live feedback so previously unseen, zero-day fraud patterns are stopped without a release cycle.

05 · Hardware & IoT

IoT & Kiosk Hardware-Based Application Development

Self-service terminals engineered as one system — operating system, device drivers, cash logic and fleet telemetry from a single team.

  • Hardened self-service terminal OS platforms — custom Linux/Debian kiosk builds with read-only root, locked-down shell and signed updates, deployed air-gapped or connected.
  • Peripheral hardware orchestration — one device broker driving bill validators and acceptors, bulk cash recyclers and thermal printers over serial, USB and Modbus.
  • Identity and card peripherals — Emirates ID and passport biometric readers and smart card dispensers integrated into the transaction flow.
  • Remote fleet telemetry — heartbeats, device health, cassette levels and tamper events streamed from every terminal to a central console.
  • Automated Cash Management Systems (CMS) — cassette-level reconciliation, replenishment forecasting and cash-in-transit scheduling.

    How Our Stack Connects

    Hardware, software, AI and networking composed by one team: delivered in-region by Xentra, engineered at our R&D headquarters. Each reference deployment pattern below traces a transaction end to end — which layer handles it, who leads that layer, and what happens when a component fails.

    Reference Architecture · Design Targets

    National Kiosk & Cash Collection Network

    Self-service terminals that take cash, card and QR at the edge, survive WAN loss, and land every note in the general ledger within seconds of acceptance.

    Stage 01 / 05

    Physical Kiosk Hardware

    HardwareR&D HQ · Build

    A hardened terminal accepts cash, card and QR through a bill validator, note recycler and a third-party PCI PTS PIN pad, all driven by a locked-down Debian image. Every peripheral event — note stacked, cassette door opened, receipt printed — is journalled on the device before anything is sent upstream.

    Components & protocols

    • Debian kiosk image
    • Bill validator · RS232 / ccTalk
    • Note recycler
    • EMV L1/L2 reader
    • TPM-backed disk encryption
    • Watchdog + tamper GPIO

    Failure mode handled

    Validator jam or cassette full → the kiosk degrades to card/QR-only mode and raises a field-service ticket carrying the peripheral fault code.

    24/7 India–UAE follow-the-sun coverage

    GST UTC+04:00 · IST UTC+05:30

    Every hour has an engineer on shift, and the regional business day is double-covered by our UAE operations desk and our R&D headquarters. Shift windows shown are illustrative; contracted hours and response times are set per SLA.

    What this means for you

    • One contract, one SLA, under UAE jurisdiction

      You sign with Xentra and hold Xentra to the service levels. How work is split between our two locations is our responsibility to manage, not yours.

    • The engineers who wrote the code are on the escalation path

      An incident that needs a fix, not a workaround, reaches the team that built the service, the firmware or the model, with no third-party vendor queue in between.

    • In-region commissioning, certification and field service

      Site surveys, installation, scheme and bank certification runs and first-line support are handled by our UAE team, on-site and in your working week.

    Engineering Rigor, Compliance & Security Matrix

    The budgets we design to and the standards that shape every build. Each entry below maps to a concrete control in the architecture, and each can be walked through with your security and audit teams.

    Gateway Processing
    Internal budget per authorisation at the gateway: parsing, routing, risk checks and HSM calls. Network transit and issuer response time sit outside it.
    High-Availability Design
    A design budget of roughly 5.26 minutes of downtime per year, met with active-active sites, quorum-based failover and no single point of failure.
    Isolation
    Zero-Trust
    Micro-segmented workloads, mutual TLS on every hop and HSM-backed service identity. Network location grants nothing.
    India-UAE Follow-the-Sun Support
    Engineering shifts at our R&D headquarters in Kerala and our operations desk in the UAE hand over with written state, so every incident keeps a named owner.

    Standards & protocols matrix

    In focus for UAE-regulated workloads

    • Cardholder data environment

      PCI-DSS Level 1 Architecture

      Cardholder data is confined to a segmented CDE. Everything outside it handles tokens, never PANs.

      • Network segmentation isolates the CDE from corporate, kiosk and analytics networks
      • PAN tokenisation at the edge; clear PAN is never written to logs or data stores outside the vault
      • Key ceremonies run inside the HSM under dual control and split knowledge
    • Payment messaging

      ISO 20022

      Account-to-account and instant-payment flows are modelled natively in ISO 20022 rather than translated at the boundary.

      • pacs.008 / pacs.002 for customer credit transfers and status reporting
      • camt.053 / camt.054 statements and notifications feed reconciliation
      • Schema validation on ingress; structured remittance data preserved end to end
    • Card switching

      ISO 8583

      The switching core parses and routes ISO 8583 traffic, with scheme-specific dialects isolated behind adapters.

      • MTI classification and primary / secondary bitmap handling in the hot path
      • Field-level validation; PIN-block translation stays inside the HSM boundary
      • STAN / RRN matching for reversals, advices and settlement reconciliation
    • Secure SDLC

      OWASP Top 10 Hardened

      Every service is built against the OWASP Top 10 and verified in the pipeline on each change, not in a pre-release sweep.

      • SAST, dependency and secret scanning gate every merge in CI
      • DAST and API fuzzing run against staging for each release candidate
      • Threat models are re-reviewed whenever a trust boundary changes
    • Cryptography

      AES-256 / TLS 1.3 Encryption

      Data is encrypted with AES-256 at rest and TLS 1.3 in transit, with mutual TLS between internal services.

      • Envelope encryption on an HSM-rooted key hierarchy with scheduled rotation
      • Short-lived certificates give each service a verifiable identity
      • Legacy protocol versions and weak cipher suites are disabled at the edge
    • Data governance

      GDPR & UAE Data Privacy Compliant

      Personal data is minimised, purpose-bound and kept in-region wherever residency rules require it.

      • Data residency: region-pinned storage and processing for UAE workloads
      • Field-level classification drives masking, retention and erasure workflows
      • Access to personal data is logged, attributable and reviewable
