What Is A Passive RFID Asset Tracking System?

RFID asset tracking will automate your operations, improve the transparency you have over your tools and equipment, and lead to you saving time and money.

With passive RFID asset tracking, you’ll be able to monitor how assets move within a building without needing to physically interact with them. In other words, you’ll be able to automate location tracking and auditing operations.

Find out more about passive RFID asset tags and RFID asset tracking, here.

Passive RFID asset tracking works through the use of passive RFID tags. These asset tags link your physical assets to digital counterparts. You will have hardware that can read these tags and couple up the tag and the asset.

In other words, if you’re using passive RFID asset tracking for construction equipment tracking, you’ll stick passive RFID labels onto your tools and equipment. Each of these tools will have a unique profile on your asset tracking software, then you can use the label on the tool to link the profile to its physical counterpart.

There are two main bits of hardware that you can use when it comes to RFID asset tracking. Both have different levels of automation.

Handheld RFID asset tracking uses handheld readers which link to your asset tracking app via BlueTooth. This way, you’ll be able to speed up audits and location tracking with ease.

This type of asset tracking works in a similar way to QR code asset management, only you will be able to scan from a distance without a line of sight.

This means that you can use standard asset management operations from a distance to track high-value collections where a tag cannot be visible.

Passive fixed RFID asset management uses passive fixed RFID readers. These readers are placed in tactical locations in your building and read your passive RFID asset tags when they’re in range.

As fixed RFID readers utilise antennas, they will also be able to track which directions your assets are moving in. In practice, therefore, if you’re using asset management to speed up audits for healthcare operations, your fixed readers will pick up when an asset moves from ward A to B, for example.

This provides a much higher level of automation, allowing you to track your assets’ movements with minimal physical interaction.

Passive RFID asset tags don’t have a battery, unlike active tags. Passive RFID tags only have two main components, an antenna and a microchip.

These tags are called “passive” as they work from the radio frequencies emitted by your handheld or fixed readers. In other words, these tags will pick up the frequency sent out by your fixed RFID reader and bounce it back to indicate that this unique tag is in range.

There are a few different types of passive RFID asset labels and they differ in functionality. For example, Ultra High Frequency (UHF) tags will have a higher read-range than High Frequency (HF) or Low Frequency (LF) tags, as their read range’s radius will be larger.

There are also different materials to ensure that some passive tags don’t interact with metallic surfaces and become nullified, for example.
