Empowering Retail & Smart Services with Resilient, Secure IoT SIM Solutions

Why ePOS Connectivity Matters

Modern ePOS systems are central to seamless transactions — from card readers and barcode scanners to integrated smart tills and Android-based payment devices. With the surge in contactless payments and SoftPOS adoption, connectivity must be secure, fast, and fail-safe.

Conventional connectivity, however, can’t meet the reliability required for business-critical services. That’s why many service providers now depend on enterprise-grade IoT SIMs — and increasingly, rSIMs — to ensure maximum availability and flexibility.

ePOS Terminals

What Are ePOS SIM Cards?

ePOS SIM Cards are purpose-built mobile connectivity solutions that connect payment terminals to cellular networks (4G/5G) and deliver:

  •  Encrypted communications for PCI DSS compliance
  •  Multi-network access to eliminate signal blackspots
  •  Secure cloud connectivity for remote management
  •  Compatibility with Android-based terminals and mPOS systems

CSL’s ePOS SIMs are engineered for retail and unattended environments — from mobile payment readers to vending machines, kiosks, and smart ticketing.

Introducing the rSIM: Dual-Path Resilience for Mission-Critical Transactions

CSL’s solutions enable dual-path communications — either by:

  • A single Dual Path intelligent rSIM
  • Combining two discrete multi-network IoT SIMs from separate core infrastructures, or
  • Pairing cellular with Wi-Fi or wired LAN

This means even if one network or SIM provider experiences an outage or maintenance window, the second path maintains connectivity — eliminating single points of failure.

For organisations requiring maximum connectivity resilience, resilient SIMs (rSIMs) go further than any other single-SIM deployments. CSL’s rSIM configurations are ideal for unattended terminals, high-value retail environments, mobile payment terminals, or remote-use scenarios.

Multi-Network and Multi-Core or Dual Path Capability: Why It Matters

Unlike consumer SIMs locked to one provider, CSL’s multi-network ePOS SIMs and rSIM intelligently switch to the strongest available signal — (for example: EE, Vodafone, O2, or Three in the UK, or Orange, Movistar, Vodafone, and Yoigo in Spain) — ensuring:

  •  Geographic deployment flexibility
  •  No service loss due to local network outages
  •  Automatic failover for greater reliability in during a core outage

Intelligent network selection avoids pitfalls like being stuck on a weak 2G signal when a better 4G connection is available. We work directly with hardware manufacturers to optimise firmware and modem logic for best-in-class performance.

Smart Vending

Android PoS, SoftPOS & Smart Vending

The evolution of POS hardware now includes:

  • Android-based PoS terminals with barcode scanners, QR cameras, and modular accessories
  • SoftPOS apps that turn smartphones into secure contactless payment terminals
  • Smart kiosks and vending machines with built-in connectivity and remote management

Each of these devices requires high-availability data paths. CSL provides preloaded, factory-fitted ePOS SIM cards and plug-and-play rSIM options for nationwide deployment and remote monitoring.
