Some assets punish their tags — heat, moisture, knocks, pressure washing. This 85×20 mm ABS tag is molded for that reality: a hard injection-molded shell over an aluminum-and-PET antenna, sealed to IP68 and rated from -20 to 100 °C in service with storage tolerance to 150 °C. Fix it with adhesive or screws to metal, walls, wood or plastic and it stays put for years.

Performance comes from an Impinj M781 chip that reads up to 6 meters on metal with a fixed reader at 902–928 MHz (2 W ERP). Memory pairs a 128-bit EPC with 512 bits of user space, rewritable 100,000 times, and every batch passes Voyantic consistency testing. Encoding plus printed text, barcodes and color artwork are available for personalization.

Ordering and customization

Supplied through ISO 9001 partner lines, the tag can be adapted in color, printing and EPC/TID encoding to match your asset system. We answer quotes within 24 hours, send free samples freight collect in 3–5 working days, and complete mass production 7–15 days after artwork approval.

Ordering this product

Sampling, quotations and supply through Rivotag.

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.
