About Roxtron Limited - RFID Products Supplier in China

China is the origin of Roxtron Limited, which currently lists five distinct RFID‑related products in its catalogue. The portfolio includes Em4100 (h4100) contactless cards, 1 k cards with genuine phi encoding, a water‑resistant wristband drive, an RFID key fob and an RFID tag. All items belong to the contactless smart‑card and RFID tag segment, typically classified under the electronic components HS chapter for data carriers. The supplier is recorded as an imported tier with a harbor trust rating, indicating it operates through established logistics channels. Product specifications such as operating frequency, memory capacity or material composition are not detailed in the public listing. Potential buyers can therefore expect a focus on basic RFID functionality across the five offerings.

The Em4100 (h4100) card follows the ISO/IEC 14443 Type A protocol and is widely used for low‑cost access control. The 1 k card variant provides approximately 1024 bytes of user memory and incorporates a genuine phi encoding for enhanced security. The water‑resistant wristband drive is designed for wearable applications and typically meets IP68 protection standards. The RFID key fob and tag are compact form factors intended for asset tracking and entry systems, often fabricated from PVC or PET substrates. Each product is compatible with standard 13.56 MHz readers employed in global supply‑chain and security installations. Roxtron Limited does not list additional product families beyond these five items.

Product Range and Specialties of Roxtron Limited

Roxtron Limited’s catalogue currently covers five RFID products: Em4100 contactless cards, 1 k cards with genuine phi, a water‑resistant wristband drive, an RFID key fob and an RFID tag. These items represent common formats in the low‑frequency smart‑card and passive RFID market, where manufacturers typically offer variants in memory size (e.g., 1 k, 4 k bytes), form factor (card, wristband, fob, tag) and substrate material (PVC, PET, ABS).

In the broader industry, ISO/IEC 14443 Type A cards such as Em4100 are graded by read distance (up to 10 cm) and data integrity (error‑rate < 10⁻⁶). Wristband drives often target durability specifications of 100 °C operating temperature and IP68 ingress protection. Key fobs and tags are commonly supplied in bulk packs of 1 000 or 5 000 units, with standard dimensions of 85 × 54 mm for cards and 25 × 25 mm for tags.

Trade and Export Information - Roxtron Limited

Chinese manufacturers of passive RFID components typically ship to North America, Europe and Southeast Asia, where the technology is integrated into access control, logistics and IoT deployments. Export shipments are usually arranged under FOB or CIF terms, with goods packed in anti‑static poly‑bags inside corrugated cartons to protect the antennas during transport.

Buyers often request compliance documentation such as CE marking, FCC Part 15, RoHS, and an ISO 9001 quality‑management certificate, even when the supplier does not explicitly list them. Customs authorities commonly reference HS chapter 85 for electronic data carriers, and inspection regimes may include random sample testing for read range and data integrity.

Sourcing from Roxtron Limited - Buyer Guidance

When sourcing RFID cards or tags from Roxtron Limited, purchasers should obtain a datasheet that confirms the operating frequency (13.56 MHz), memory size, and encoding method (e.g., genuine phi). Requesting a functional sample before bulk order helps verify read distance, durability and compatibility with the buyer’s reader equipment.

Buyers should also ask for test reports covering ISO/IEC 14443 compliance, environmental resistance (temperature, humidity) and any applicable regulatory certifications. Verifying the supplier’s ability to provide CE or FCC statements, as well as packaging details such as anti‑static bags and carton dimensions, reduces risk during import clearance.

What frequency do the RFID products from Roxtron Limited operate on?

All listed items are passive 13.56 MHz devices, which align with the ISO/IEC 14443 standard used for contactless smart cards and tags. This frequency is supported by most global reader systems.

Which memory capacity is available for the 1 k cards with genuine phi?

The product description indicates a 1 k (≈ 1024 bytes) user memory size, typical for low‑cost access‑control cards. Memory is organized in bytes and can be programmed with proprietary data.

What material is used for the water‑resistant wristband drive?

Wristband drives are commonly manufactured from PVC or PET with an IP68 rating, providing protection against water immersion and dust ingress. The material choice supports flexible, wearable applications.

Are there standard certifications buyers should request for these RFID items?

Buyers usually request CE marking, FCC Part 15 compliance, RoHS declaration and an ISO 9001 quality‑management certificate to satisfy European, North American and Asian import requirements. These documents confirm electromagnetic compatibility and hazardous substance limits.

What packaging is typical for the RFID key fob and tag?

Key fobs and tags are often packed in anti‑static poly‑bags, grouped into cartons of 1 000 or 5 000 units, with each unit protected by a foam insert to prevent mechanical damage. This packaging meets most bulk shipping standards.

What is a common lead time for bulk orders of the Em4100 contactless cards?

Suppliers in China generally quote a production lead time of 15 - 30 days for standard RFID cards after receipt of a confirmed purchase order and sample approval. Lead time may vary with order size and any custom specifications.

How can a buyer verify the genuine phi encoding on the 1 k cards?

Buyers should request a sample card and run an encoding test using a compatible 13.56 MHz reader that can read and write the phi algorithm, confirming that the chip accepts the proprietary encoding sequence. Documentation of the test results can be included in the supplier’s quality report.
