On September 16, 2026, BW verified RFID reading with a Zebra TC27 and the RFD40 sled (RFD4031-G00B700-WR) over a USB-C cable. The app detected the reader with the Zebra API3 SDK, read a tag and displayed its product.

01

What was tested and the result

Field-verified means that BW tested the complete flow on physical equipment, with the date and firmware in this record. For a different version, contact sales before purchasing.

  1. Connection

    RFD4031-G00B700-WR by USB-C cable.

  2. Detection

    Automatic, with the Zebra API3 SDK.

  3. Reading

    One EPC in Scan, with its product.

02

Connecting the RFD40 to the TC27

  • Works

    USB-C cable or TC2x adapter

    A direct USB-C cable between the TC27 and the sled, or the RFD40 adapter for the TC2x family.

  • Does not work

    Holder without a data connection

    The holder supports the sled, but the TC27 does not detect it as a reader.

03

What the Chainlink app does with the sled

  • Reads EPCs and links them to product, lot, serial number, pallet and location
  • Looks up items, picks, counts and validates transfers with the sled trigger
  • Continues to read barcodes and QR codes with the TC27

RFID is available in Professional and Enterprise. A handheld with RFID does not require a device license.

04

Checks when the sled does not read

  • The sled is connected by USB-C, not only mounted
  • The app has detected the reader
  • The account is on Professional or Enterprise
  • If the app does not recognize an item, its tag is not registered
05

Other handheld RFID devices

The Zebra RFD90 sled and the MC3300R and MC3300xR handhelds are compatible. The Honeywell IH21 and IH40 sleds are under validation. None of them is field-verified; see hardware.

Frequently asked questions

For any other question, contact sales.

Does the RFD40 work over Bluetooth? +

The BW verification was performed with the sled connected to the TC27 by USB-C cable. That is the connection BW recommends and the only one verified.

Does the holder supplied with the sled work? +

Only if it provides a data connection. A holder that only supports the sled physically does not connect it to the TC27, and the app does not detect the reader.

Does it work with an RFD90 or another Zebra handheld? +

The RFD90 and other Zebra handhelds are compatible with the Zebra SDK the app uses, but BW has not verified them in the field.
