Product Range and Specialties of Uniontags Technology Limited

The catalogue shows five distinct RFID products: a 13.56 MHz smart card with MF1 S70 chip, a 13.56 MHz epoxy tag for access control, a 125 kHz silicone wristband using EM4200 ID, a 125 kHz key fob that integrates TK4100 and EM4200/T5577 chips, and a roll of 13.56 MHz ICODE SLI‑X adhesive stickers. These items correspond to common RFID formats such as PVC cards, epoxy‑resin tags, silicone wearables and adhesive label media, which buyers typically select based on form factor and environmental resistance.

In the RFID industry, 13.56 MHz products usually conform to ISO/IEC 14443 (for proximity cards) or ISO/IEC 15693 (for vicinity cards), while 125 kHz devices follow ISO/IEC 18000‑2. Chip families like MF1 S70 and S50 provide 2 KB memory, EM4200 offers 1 KB, TK4100 supports 2 KB with additional security features, and ICODE SLI‑X is designed for high‑density label printing and can store up to 2 KB. Typical material grades include PVC for cards, epoxy for rugged tags, medical‑grade silicone for wristbands, and polyester‑based adhesive for stickers. Buyers often request specifications such as read distance (up to 10 cm for 13.56 MHz cards, up to 5 cm for 125 kHz wristbands), operating temperature range (-20 °C to +70 °C), and durability ratings like 10 000 bend cycles for flexible formats.

Trade and Export Information - Uniontags Technology Limited

Chinese manufacturers of RFID components frequently ship to North America, Western Europe and Southeast Asian markets, where logistics are usually organized under FOB Shanghai or CIF Los Angeles depending on buyer preference. The products fall under HS Chapter 85 (electrical machinery) for the electronic modules and Chapter 90 (optical, photographic, measuring, checking instruments) for the finished cards and tags, with sub‑headings such as 8523.30 for disc, tape or other media for sound recording or other recording, and 8543.70 for parts of electronic integrated circuits. Importers typically require CE marking for the European Union, FCC certification for the United States, and RoHS compliance to verify restriction of hazardous substances. Packaging is commonly done in sealed poly‑bag units placed inside cardboard cartons, with each carton holding 10 000 cards or an equivalent number of wristbands, allowing efficient loading into 20‑ft or 40‑ft containers. Export documentation usually includes a commercial invoice, packing list, certificate of origin and, when requested, a test report confirming ISO/IEC compliance.

Sourcing from Uniontags Technology Limited - Buyer Guidance

When evaluating Uniontags Technology Limited, buyers should request a copy of the ISO/IEC test report for the specific chip model (e.g., MF1 S70, EM4200) to confirm frequency, memory size and read range. Samples of the PVC card, epoxy tag and silicone wristband are advisable to verify material durability, adhesive strength for the sticker roll, and overall print quality. Verify that the supplier can provide CE, FCC or RoHS certificates if the buyer’s target market requires them, even though the catalogue does not list existing certifications. Confirm the minimum order quantity, typical lead time (often 15‑30 days for bulk production) and the packaging format (poly‑bag per 1 000 units, cartonized for container loading). Ensure that the supplier can supply a material safety data sheet (MSDS) for the epoxy and silicone compounds used in the products.

What frequencies are covered by the RFID products listed by Uniontags Technology Limited?

The catalogue includes items operating at 13.56 MHz and 125 kHz, which are the two most common RFID frequency bands for access control and inventory tracking.

Which chip families are used in the smart card and key fob products?

The smart card uses the MF1 S70 chip, the epoxy tag uses the MF1 S50 chip, the wristband employs the EM4200 ID chip, the key fob combines TK4100 and EM4200/T5577 chips, and the sticker roll uses the ICODE SLI‑X chip.

What material formats are indicated for the RFID products?

Product titles suggest PVC for the smart card, epoxy resin for the access‑control tag, silicone for the wristband, and an adhesive label substrate for the sticker roll.

Are any industry certifications listed for Uniontags Technology Limited?
