RFID labels printed and encoded from Chainlink
Chainlink WMS prints UHF RFID labels. As it prints, the printer writes to the chip a 96-bit EPC that Chainlink generates and registers, and each later read is linked to its product, pallet or location.

What a UHF RFID label is
A UHF RFID label is an adhesive label with a chip and an antenna, which can also carry printed text and a barcode. See EPC.
- The EPC Gen2 standard stores an identifier, the EPC
- Tags are read without line of sight and several at a time
The EPC Chainlink writes
Chainlink writes a 96-bit identifier (24 hexadecimal characters) that is unique in your account.
- Products, pallets, locations and document labels carry one
- The EPC is registered when the label is printed; no separate registration is required
Printing and encoding a label
Antenna calibration consumes labels. It is optional, and Chainlink Wizard states how many labels it will use.
-
Enable encoding
In the label template.
-
Print
The printer writes the EPC while it prints.
-
Confirm
The printer confirms the write and Chainlink links the EPC.
Printers that encode RFID
The ZT411R, ZT421R, ZT610R, ZT620R, ZD611R and ZD621R are compatible by network with Chainlink Wizard.
- The ZT610R is field-verified for setup and printing
- That test used labels without a chip; encoding will be verified with an RFID roll
Choosing the tag
The read range depends on the tag, the product and the antennas, so a test with your product is recommended before tagging all of the stock. Chainlink does not sell tags.
- Cardboard, plastic or fabric
- A standard UHF tag usually works.
- Metal
- Metal reflects the signal and requires an on-metal tag.
- Liquids
- Liquids absorb the signal, so placement and antenna matter.
- Full pallets
- The tag goes on an accessible face, at the height of the antennas.

Frequently asked questions
For any other question, contact sales.
Does Chainlink sell RFID tags? +
No. Tags and printers are purchased from a distributor. Chainlink writes and registers the EPC of each tag and prints on it.
Can tags that already carry a supplier EPC be used? +
Chainlink links the EPCs it registers to your item, pallet or location. A tag that is not registered in your account is reported as unknown in the reads.
What happens if the printer cannot write a tag? +
The print is not accepted: the printer’s RFID response must confirm the write. After an RFID error, the RFID jobs of that printer wait 90 seconds before continuing.
