In the fast-moving world of wireless device testing and R&D, engineers need tools they can depend on. One small but critical component is the test white card. At HKCARD ELECTRONICS CO.,LIMITED (commonly referred to as HKCARD), we manufacture and supply high-quality 2G test white cards and NFC test white cards tailored for labs, factories, and field testing environments. Whether you are working with GSM modules or NFC-enabled prototypes, HKCARD provides clean, blank cards built to support precise and repeatable test results.
Below, we break down what these cards are, how they work, and why HKCARD is the go-to supplier for many global tech firms.
1. Deep Look: 2G Test White Card – Lexun Nano Type (PC Material)
When testing 2G GSM devices, an engineer often needs a blank SIM card with no carrier profile or encryption keys. This is exactly where the 2G test white card Lexun Nano type comes in. Made from durable polycarbonate (PC), this card is designed to fit standard SIM slots and withstand repeated insertion, removal, and handling in a lab environment.
Hardware Specs at a Glance
- Card body material: High-grade PC
- Chip platform: Lexun Nano (optimized for 2G signaling tests)
- Card format: Standard SIM size (easily punched down to Micro or Nano if needed)
- Surface finish: Plain white/blank, no artwork or pre-printed data
- Unit sales: Available per piece, giving teams flexibility to order only what they need
Why Labs Choose This Card
- Clean test environment: No stored operator data means no interference during network simulation.
- Physical durability: PC material holds up better than standard PVC under constant lab use.
- Lexun Nano reliability: This chipset is widely recognized for stable 2G communication and easy integration with common test tools.
Typical Testing Scenarios
- 2G module power-on and network registration tests
- Antenna and RF performance checks
- Base station simulator compatibility
- Embedded SIM socket verification
- QA line testing before mass production
2. NFC Test White Card – Lexun NANO Type (Per Piece)
For projects that involve near-field communication, having a reliable blank test tag is just as important. HKCARD supplies the NFC test white card Lexun NANO type, sold per piece for maximum ordering flexibility. This card acts as a blank canvas for NFC testing, whether you are working on payment terminals, access control readers, or smart packaging prototypes.
Key Product Details
- Chip: Lexun NANO NFC chipset
- Operating frequency: 13.56 MHz (standard NFC band)
- Material: Durable card stock designed for repeated tap tests
- Appearance: Plain white card, easy to label or mark for test tracking
- Packaging: Single piece, bulk options available for larger R&D teams
Where These Cards Are Used
- Testing NFC payment terminals and POS systems
- Smart home and IoT device pairing checks
- Access control reader validation
- NFC antenna and signal strength measurements
- University and corporate R&D labs
Why Per-Piece Ordering Matters
Many suppliers require minimum orders of hundreds or thousands of units. HKCARD understands that test environments often need only small quantities. Our piece-by-piece supply model helps labs keep costs low and inventory lean.
3. HKCARD Quality: What Sets These Test Cards Apart
All test cards from HKCARD ELECTRONICS CO.,LIMITED are produced under strict process control. We don’t just print plastic and embed chips. Each card goes through careful material selection, chip programming checks, and physical tolerance verification before shipment.
Material Advantage of PC
For 2G test cards, the move to polycarbonate is deliberate. PC offers better heat resistance and mechanical strength compared to standard PVC. This is especially helpful when cards are used repeatedly in socket testing jigs.
Lexun Chip Platform Consistency
Both the 2G and NFC variants use the Lexun platform, which engineers appreciate for its stable electrical performance and wide tool compatibility. Whether you run CMW500, CMU200, or custom test scripts, Lexun-based cards work without constant reconfiguration.
Clean, Label-Ready Surface
The blank white design is intentional. Engineers can write test IDs, dates, or configuration notes directly on the card surface, simplifying test management when multiple cards are in rotation.
4. Ordering and Customization
HKCARD keeps the ordering process straightforward. You can request standard configurations as described, or reach out for specific custom needs.
Custom Options Available
- Card size adjustments (standard, micro, nano cutout)
- Material substitutions for special environments
- Chip variations if your test setup needs a different Lexun firmware version
- Bulk packaging for large-scale testing projects
