HKCARD ELECTRONICS CO.,LIMITED (HKCARD) provides an eSIM (eUICC) secure connectivity solution for consumer electronics, automotive, and IoT devices. The solution follows international and domestic standards and is built for high security, stable performance, and long-term reliability, with a one-stop delivery model covering chip, OS, production, and LPA enablement.

 What HKCARD eSIM Delivers (Security, Performance, Reliability)

HKCARD eSIM is designed for devices that must stay connected and protected in real-world conditions.

Key capabilities

  • High security: secure element-grade protection for credentials and profile storage
  • High performance: 32-bit core and up to 2M Flash for fast operations and larger profile capacity
  • High reliability: suited for long lifecycle products (including automotive supply chains)
  • One-stop support: chip + OS + manufacturing + LPA reference implementation

Certified security and quality

  • Common Criteria (CC) EAL6+
  • UnionPay chip security certification
  • China Commercial Cryptography (Guomi) Level 2
  • AEC-Q100 (automotive-grade qualification)

Chip + Package (High-Performance eSIM Secure Chip)

HKCARD supplies a high-performance eSIM secure chip with options suitable for mainstream embedded form factors (such as MFF2-type packaging, based on project needs).

Core specifications

  • 32-bit core
  • 512K / 2M Flash NVM (depending on configuration)

This platform is built to support frequent network switching, secure storage, and repeated profile lifecycle operations.

eSIM OS Compliance (GSMA SGP.22) and Network Support

HKCARD eSIM OS is aligned with GSMA SGP.22 requirements for consumer remote SIM provisioning.

OS and network support

  • GSMA SGP.22 compliant eSIM OS
  • Supports 2G / 3G / 4G / 5G device scenarios (subject to device/baseband capability and operator configuration)

For global deployments, compliance and interoperability reduce rollout risk and shorten operator onboarding time.

 Manufacturing, Personalization, and GSMA SAS-UP

HKCARD supports eSIM production flows that fit different factory setups and supply chains.

Production and personalization options

  • Wafer-level personalization
  • Personalization after packaging
  • GSMA SAS-UP certified manufacturing process (for eSIM production security requirements)

This helps customers manage secure data injection and traceability while keeping throughput stable for volume orders.

 LPA, Multi-Profile Download, Global Coverage, and Customer Value

LPA (Local Profile Assistant) support

HKCARD provides an LPA reference implementation for:

  • Android
  • Linux
  • RTOS

This helps device makers reduce engineering effort when enabling eSIM download and activation.

Multi-profile capability

  • Supports downloading up to 10 profiles
  • Users can switch operators more easily for travel, multi-network service, or product segmentation

Global operator coverage

  • Works with 200+ operators worldwide (coverage depends on operator RSP readiness and certification plans)

Cryptography

  • Supports mainstream international algorithms (details available upon request to match compliance targets)

Customer value (what it changes for your product)

  1. Ready to connect with multiple activation methods
  2. Works with mainstream pinouts, usually no PCB redesign, and reduces the need to build a new LPA from scratch
  3. More reliable device-to-eSIM connection, and saves PCB space for compact designs
  4. Lower integration workload, shorter adaptation cycle, and faster time to market

Solution architecture (high-level)

  • Operator / Profile Owner
  • Operator or Service Provider Profile ownership
  • Profile management for download, activation, and lifecycle control

Typical Use Cases

  • Consumer electronics: smartphones, smartwatches, laptops, tablets
  • Automotive electronics: T-BOX / telematics units
  • Finance: POS terminals
  • IoT devices: gateways, trackers, industrial devices (based on product requirements)
