Import 13.56mhz S50 Epoxy Rfid Tag For Access Control — Buy in Bulk from Supplier in China

This 13.56MHz epoxy RFID tag from Uniontags Technology Limited is designed for access control systems, using the NXP Mifare S50 chip which operates on the ISO 14443A standard. The tag has a typical reading distance of 1 to 5 centimeters, weighs 5.8 grams plus or minus 0.5 grams, and is available in standard colours such as white, red, yellow, black, and blue, with custom options available on request. Its housing uses quality PVC, PET, or ABS materials, and the epoxy coating provides a durable, smooth finish suitable for frequent handling.

The S50 chip is a common choice in contactless smart card technology, offering 1 kilobyte of EEPROM memory partitioned into 16 sectors, each with two authentication keys. Typical industry specifications for such tags include a memory structure that supports multi-application use, and a data retention period of up to 10 years. Uniontags offers various surface finishes including matte, gloss, frosted laminated, and UV film, with printing methods such as offset, silkscreen, and glittering effects, allowing for detailed branding or identification marks.

These tags are commonly purchased by security system integrators, corporate facility managers, and event organisers for building access, time attendance, and cashless payment applications. The supplier states that standard carton dimensions are 50 by 4 by 8 centimetres, and they support custom encoding and printing on both sides in up to full colour. Buyers should confirm the exact minimum order quantity and lead times directly with Uniontags, as these details are not specified in the listing.

Uniontags Technology Limited is based in Putian, Fujian, China, with its address at the 7th floor of the 4th Building in Zhengrong Time Square. The supplier is listed with a 'harbor' trust tier on the platform, though its current response rate is shown as 0.00 percent, meaning buyers should allow extra time for initial replies or use alternative contact methods if urgency is high.

The listing focuses on RFID tags and related products, indicating a specialization in radio-frequency identification hardware. While the supplier mentions certifications such as CE, FCC, RoHS, and ISO in the product description, the listing does not provide specific certificate numbers or third-party verification links. Buyers interested in bulk procurement should request these documents directly to confirm compliance for their target markets.
