A barcode can be copied. A secure chip holds a secret.
Three ways to identify a product, and what each proves. Our tags carry NFC and RAIN RFID on one inlay: a phone at the counter, a reader at the dock.
NFC's short range is the point: a tap means the reader was at the product. RAIN's long range clears a pallet in one pass. Short bars are drawn at a minimum width.

Which carrier, for which job.
The law often names a printed code. These guides show where it is enough, and where a chip pays for itself.
NFC or QR for battery passports
The QR is the legal carrier. Where it falls short over a battery’s life.

About the technology.
How does dual-frequency NFC + UHF work?
One chip, two radios, one identity. Phones read the NFC side; dock readers read the UHF side in bulk. Both always match.
Why can't a 2D barcode alone authenticate a product?
A printed code is visible data, so it can be photographed and reprinted. Telling a real unit from a copy needs a secret that cannot be seen. That is what a secure chip is for.
What is the barcode-plus-chip pair?
The GS1 2D barcode plus a dual-frequency chip on the same unit. The barcode is the open ID; the chip holds a secret key.
What is the No-Encode workflow?
Our No-Encode workflow means no payload is written on your production line. Tags are bound to their GS1 identity in the field, so there is no encoding step to slow the line.
How are the tags secured?
Our secure tags use cryptographic chips designed to be clone-resistant. Every tap is written to an append-only EPCIS 2.0 custody log.
