RFID Barcodes

Tracking Chemical Containers with Radio Frequency Identification (RFID) Barcodes

The EH&S chemical inventory group is pleased to announce that we will begin using new Radio Frequency Identification (RFID) barcode stickers to manage chemical inventory. The new barcode stickers will appear on all inventoried chemical containers starting in October 2018, and once fully implemented, RFID barcode technology will greatly facilitate EH&S collection of chemical inventory data.

The RFID tags are encoded with an 8-digit barcode number. The 8-digit numbers are also visibly printed along with a UNR CHEM ID one-dimensional barcode. The RFID stickers are designed to protrude off the side of the container as "flag tags" (shown in the picture). Please DO NOT REMOVE or tape down these tags.

Procedure for Applying RFID Barcodes to Chemicals Shipped in Sealed Cans

Some chemicals are shipped inside metal cans and it is safer to deliver them inside the cans preserving the original seal. The end users are thus responsible for placing the chemical inventory Radio Frequency Identification (RFID) flag-tag barcode on bottles after opening the can in the laboratory. Follow the steps below when affixing an RFID barcode to a chemical container.

  1. step 1 remove barcode backing Remove the pre-folded RFID barcode from the waxed paper backing.
  2. step 2 apply label vertically Adhere the label vertically to the right of the chemical label.
  3. step 3 allow label to stick out like a flag Ensure that the barcode sticks out horizontally like a flag.
