RFID Tracking System Technology – Radio Frequency Identification (RFID) is the use of radio waves to read digital data coded onto tags. The scanned information can then be added into a business’s database for further use. RFID works under the banner of Automatic Identification and Data Capture (AIDC) mechanism.
By automating the data entry process, it minimizes the need for human intervention in daily business tasks. Using RFID scanners eliminates human errors, increases the accuracy of data and allows for improved decision making.
RFID technology generally consists of three components: a tag/smart label, a reader, and an antenna. The tag embedded in a particular asset transmits radio signals to the reader. Each reader has a processor that converts radio signals into a digital form so the data can be uploaded onto the company’s database.
There are two ways to scan and process radio signals depending on the location and configuration of the RFID tag.
- Active RFID system instantly captures data from the tags using in-built processors that convert radio signals to digital data.
- Passive RFID systems work without an antenna processor. They send out radio signals transmitted by an RFID tag to a remote antenna processor that then converts them into a digital form for use by the system.
To cater to the variety in business processes at different organizations, RFID readers come in both handheld and fixed forms. Fixed RFID scanners are suitable for use in large warehouses that host assets of different sizes.
An active fixed RFID reader can pick up transmissions from an item located within 1500 feet of its radius, whereas a passive fixed scanner can pick radio signals from 600 feet within its radius. Handheld scanners, on the other hand, are used for scanning small-sized items on an individual basis.
Benefits of RFID systems
Ever since its introduction, RFID technology has evolved with time to adapt to changing industry trends. Using it in your daily processes can help your business in a variety of ways.
RFID requires less effort than its predecessors, primarily because it can read tags even at a distance. Fixed RFID readers also allow for mass scanning of multiple items. This means you can squeeze out the extra seconds you would’ve spent on tedious individual scanning to focus on other important tasks.
- It provides access to real-time data
With RFID, any changes in the quantity and location of asset stock and inventory items are updated in the online database right away. This makes it easier to forecast demand and develop procurement lists. Let’s say, you work for a construction company and an ongoing project demands a greater number of forklifts than usual.
Since the system lowers the available quantity, you can quickly replenish your assets without compromising on your project schedule.
- It prevents theft and misplacement of inventory
It often becomes hard to track your assets if they are being used by hundreds of employees everyday. RFID labels allow you to keep tabs on where and how your assets are being deployed. Keeping a vigilant eye on your inventory prevents loss by misplacement, theft or careless handling.
