Barcodes

RFID

This page explains how RFID (Radio Frequency Identification) can be used as an alternative to optical barcodes for asset identification in xAssets.

What is RFID?

RFID uses radio waves to read data stored on an electronic tag attached to an asset. Unlike optical barcodes, RFID does not require line-of-sight between the tag and the reader -- tags can be scanned through packaging, clothing, or other obstacles. Multiple tags can also be read simultaneously, which makes RFID much faster for large-volume audits.

When to Use RFID Instead of Barcodes

Scenario RFID Advantage
Assets behind walls or in sealed cabinets No line-of-sight needed
Large warehouse audits (hundreds of items) Simultaneous multi-tag reading
Harsh environments (dirt, moisture) Tags are more durable than printed labels
High-value assets requiring tamper detection Tags can be embedded or sealed

However, RFID tags and readers are typically more expensive than barcode labels and scanners, and the initial setup is more complex. For smaller inventories or environments where line-of-sight is not an issue, traditional barcodes are usually more cost-effective.

Using RFID with xAssets

To use RFID with xAssets:

  1. Encode each RFID tag with the asset's barcode identifier (the same value stored in the Barcode field in xAssets).
  2. Attach the RFID tag to the physical asset.
  3. Scan using an RFID reader that can export scanned tag data to a file.
  4. Import the scanned data into xAssets, following the same import process used for intelligent barcode scanners. See TracerPlus Configuration for details on the import workflow.

Tip: Because RFID data is imported in the same format as intelligent scanner data, you can use the same audit types, forms, and review workflows. The only difference is the physical scanning hardware -- the xAssets side of the process is identical.

Limitations

  • RFID readers are more expensive than barcode scanners, typically starting at several hundred dollars.
  • Tag encoding requires additional setup and equipment.
  • Not all RFID readers export data in formats compatible with TracerPlus -- verify compatibility before purchasing.
  • Metal surfaces can interfere with some RFID frequencies, requiring special tag types for metal assets.
