Posted by An RFID tracking system is designed for automating the entire supply chain and management process for physical assets. It helps you get instant notifications and data related to the tracking process so that you can take any necessary actions. In addition, an RFID asset tracking system can track multiple assets simultaneously; it helps in saving time and money. But how does an RFID asset tracking system work? Below, we will explain to you the entire process along with the different types of tags and benefits.
What is an RFID Asset Tracking System?
RFID, or Radio Frequency Identification, tracking is the way through which one can automate the entire tracking and management process that involves physical assets. In simple words, RFID asset tracking is the digital method of tracking and managing all physical assets that go through the supply chain.
There are various ways through which a company can implement RFID asset tracking, like tags, labels, QR codes, etc. In this method, the data is encoded on an RFID tag which is then attached to the physical asset. Finally, the tag emits a signal which further starts the tracking process.
How Does RFID Asset Tracking Work?
To implement an RFID tracking system, you need four things:
- RFID Tags
- Antenna
- RFID Reader
- Computer linked with Asset Tracking Software
Firstly, the tag is embedded with identifying information, or Electronic Product Code (EPC), about the product, after which it is attached to the physical asset.
Once the tag is in its place, and the vehicle starts moving, it sends over continuous pulse signals. These pulse signals are received by an antenna that is wirelessly connected to an RFID reader.
The RFID reader then further transmits the data to the system that is linked with an RFID asset tracking software, where it is stored for future usage. This is the basic flowchart on how an RFID tracking system works. However, the entire system also depends on the type of RFID tag you select, after which the following steps are similar.
Types of RFID Tags
Basically, RFID tags are divided into three categories: active, passive, and semi-passive. Each tag is designed for a specific type of asset tracking, based on which you can select the best suit for your company.
1. Active RFID Tags
Active RFID tags contain a battery and transmitter that allows them to transmit their own signals without any need for triggering. Due to this, active RFID tags have a long read range, upto 150 meters.
The tag emits signals that are then read by an antenna and then further sent to the reader to pass on the information. There are two types of Active RFID tags: transponders and beacons. In the case of transponders, the tags need to be triggered by the RFID reader signal to emit pulse signals, after which the asset tracking system starts.
On the other hand, beacons are designed in a way where they do not need any external trigger to emit signals. Instead, they are set to give out signals at a set time which are then received by the antenna.
Though active RFID tags have tons of benefits, like long-range reading, real-time tracking, etc., they are expensive and have a limited shelf life of 4-5 years. You can only reuse the tag after changing its battery.
2. Passive RFID Tags
Passive RFID tags do not have their own batteries or transmitters. In other words, these tags cannot send their own signals unless you activate them by scanning the code through an RFID reader.
Once the passive RFID tag receives the signal, it will start emitting signals, and the process will become streamlined. These tags come in various shapes and sizes, designed to work under extreme environmental conditions. They are affordable and can last for decades before they die due to excessive wear and tear.
3. Semi-Passive RFID Tags
Semi-passive tags, as the name states, is a passive tag with an additional battery. They function like passive RFID tags, but due to the presence of batteries, the read range is more than that of passive tags.
Additionally, semi-passive RFID tags also allow you to include real-time tracking, which is quite tricky in passive tags. However, these tags do not come with a transmitter, so their reading range is less than active RFID tags.
Benefits of Using RFID Asset Tracking System
The major question that arises now is what are the benefits that a company can get by implementing RFID asset tracking solutions? To answer the above question, here are some valuable benefits you can get through RFID asset tracking.
- As RFID automates the entire process, it further reduces labor costs that come with manual management and tracking. RFID asset tracking system also prevents human interference, so there’s no pilferage and mistakes.
- Though implementing a full-fledged RFID asset tracking system is expensive, the returns you will get are worth it. Installing an RFID tracking system is a one-time investment that will last for years and yield good results.
- With a proper RFID tracking system, the chances of theft and pilferage are less. As RFID asset tracking system provides you with real-time data, you get instant alerts if any mishaps occur.
RFID asset tracking system is the need of the hour. Companies dealing with cargo deliveries and physical assets need to implement an RFID tracking system to maintain transparency and prevent mishaps.
