Counting a jewelry showcase used to mean opening it. With this tail tag looped onto every piece, a reader pass over the closed case returns the full inventory — each necklace, ring and earring answering with its own 128-bit EPC. A further 128 bits of user memory hold price codes, purity marks or provenance references.

Physically, the tag is engineered around the merchandise. Waterproof white PET, thin and light, wraps without abrading metal or stones, and the folded head presents just 25×13 mm of printable surface — enough for a barcode at 600 dpi. The Qstar-7U chip reads at -17 dBm sensitivity out to roughly 4 meters over ISO/IEC 18000-6C / EPCglobal Class 1 Gen 2.

Ordering and customization

Sourced through ISO 9001-certified partner lines, the tag is customizable in chip, size, face material, printing and EPC/TID encoding. Rivotag answers quotes within 24 hours, sends free samples freight collect in 3–5 working days, and completes production 7–15 days after artwork approval.

How fast will I get a quotation?
We reply to every enquiry within 24 hours with a specific recommendation — chip, antenna, face material and adhesive — plus tiered unit pricing for the quantities you request.
Can I get samples before ordering?
Yes. Samples are free of charge (freight collect) and dispatched within 3–5 working days, so you can verify read performance on your own material before committing to production.
What is the production lead time?
Mass production typically ships in 7–15 days after artwork approval. Our partner factories run 30+ production lines with a combined capacity of about 1.5 billion tags per year.
Are you the manufacturer?
We are an independent supplier, not the factory. Production runs on audited partner lines in China that hold ISO 9001 certification and ARC-certified standard designs; we handle engineering review, sampling, QC and logistics, and remain your single accountable contact.
Can you customize size, chip, printing and encoding?
Yes — size, chip (Impinj, NXP, Alien and more), face material, adhesive, printing and EPC/TID encoding are all customizable. A custom antenna design typically takes 3 working days.
How is quality controlled?
Partner lines run CCD vision inspection on every roll, Voyantic RFID performance testing, and 100% read verification after encoding, under an ISO 9001 quality system. We release shipment only after QC data is confirmed.
