RFID: Understanding the Components and Types

RFID, which stands for Radio Frequency Identification, is a wireless technology that uses radio waves to identify and track objects. Its advanced capabilities make it a versatile tracking tool, with various components and types that can be tailored to specific needs. In this article, we will delve deeper into the components of RFID and the types of RFID.

RFID Components

The main RFID components include tags, readers, and software.

Tags

Tags consist of an integrated circuit, antenna, and substrate. The part of the tag that contains unique information for identification is called the RFID inlay. Tags can be attached to products, packages, shipping units, returnable assets, and more. There are two main types of tags:

  • Active Tags: Have their own power source, often a battery.
  • Passive Tags: Receive power from the reader’s antenna. Electromagnetic waves from the reader’s antenna induce current in the tag’s antenna.

Active tags have a longer read range than passive tags due to their stronger power source.

 

Reader

An RFID reader is a device equipped with an antenna to emit radio waves and receive signals from tags. It functions like a barcode reader but does not require direct contact to read information.

Types of RFID Readers:

  • Fixed Reader: Installed in a specific location and used to track the movement of goods or people passing through the area.
  • Mobile Reader: Can be carried anywhere and used to read tags manually.

Each tag within the reader’s read range is automatically activated and transmited information, such as a serial number, to the device.

 

Software and Dashboard

All data will be collected by RFID software. This software plays a crucial role in consolidating data from multiple readers, cleaning and formatting the data, and forwarding it to other systems such as ERP (Enterprise Resource Planning).

In addition, data can also be displayed on an RFID dashboard as a user interface to visualize data and monitor system operations in real-time. This allows you to gain insights into asset movement, operational activities, and potential inefficiencies.

 

RFID Frequency Types

Frequency is a measure of the wavelength used for communication between components in an RFID system. RFID systems currently operating on three frequency ranges: low, high, and ultra-high. Each frequency has its own advantages and disadvantages in terms of bandwidth and capabilities.

RFID Frequency Types can be classified into three:

Low Frequency (LF) RFID

  • Operates in the range of 30KHz to 300Khz. Most commonly used in the 125 KHz or 134 Khz frequency.
  • Short read range, around 10 cm. Ideal for applications requiring close-range identification.
  • Slow read speed. Suitable for situations that do not require fast reading.
  • High resistance to external interference. Ideal for environments with high electromagnetic wave traffic.
  • Has a smaller data transmission capacity but can function well in the presence of metal or liquids.
  • LF applications can be found in access control and animal tracking.

 

High Frequency (HF) RFID

  • Operates in the range of 3 to 30 MHz. Commonly operates at 13.56 MHz.
  • Read range is between 10cm and 1m.
  • More susceptible to interference from liquids and metals in the environment.
  • HF applications can be found in ticketing, payment, and data transfer.

 

Ultra High Frequency (UHF) RFID

  • Operates in the 300MHz to 3GHz frequency range. Most commonly used in the 860 to 960 MHz frequency.
  • Long range, more than 12 meters.
  • High reading speed. Its data transmission process is very fast, enabling the reading of large numbers of tags in a short time.
  • Sensitivity to electromagnetic interference is very high, potentially obstruct tag reading.
  • UHF applications range from store inventory to drug identification for protection.

 

 

RFID Frequency Commonly Used Today

The higher the RFID frequency, the faster and farther the data transmission range. However, the radio waves emitted are more susceptible to interference from liquids and metals in the surrounding environment.

Nevertheless, technological innovation in recent years has produced tag, antenna, and reader designs that can deliver high performance in complex environments.

UHF tags are currently easier and cheaper to manufacture compared to LF and HF tags. Therefore, the majority of RFID projects now adopt UHF technology, making it a rapidly growing market segment and easily adaptable to various sectors.

It is important to consider factors such as RFID frequency, read range, and tag durability when making your decision. By understanding the components of RFID and the different types of RFID, you can choose the right solution for your needs.

Implementation Of RFID Technology Solutions & Its Benefits For Industrial Business

In the development of digitalization technology, RFID (Radio Frequency Identification) technology is a familiar name in the industrial world. However, contrary to popular belief, RFID technology’s function is not to replace Barcode technology. In several business processes, RFID Labels/Tags will be much more economical and faster than barcode technology, notably if used for returnable assets. Perfect for track & trace (close loop process) because these RFID tags can be reused, have short tag reading time, and can be read all at once, contrary to the barcode scanning process which is generally done one by one.

RFID is part of the ‘Automatic Identification and Data Capture (AIDC) technology. Functionally, the RFID component is divided into two parts:

  • RFID Tag (to be read), composed of chips (electronic circuit) and an integrated antenna called INLAY. Generally, RFID tags have three memories to store unique ID (TID), EPC data, and user data.
  • RFID Reader is a tool used to read RFID tags. There are two types of readers: First, mobile Readers that are used by humans. Second, Fixed Readers are generally placed at gates, conveyors, zone transfer points, or auto-reading areas (without human interaction).

ACS Group, in collaboration with Zebra Technologies, has successfully implemented RFID in several Automotive Industries, Electronic Industries, and Manufacturing Industries for Returnable assets and Track & Trace Asset Applications. Both are very effective and efficient applications implemented using RFID technology.

Supply chain activities (process activities of the flow of goods from manufacturing to the hands of customers) consist of distribution, transportation, and transfer of goods status. To support these activities, Zebra Technologies provides solutions for RFID technology, Mobile Readers (Zebra MC333x/MC339x, RFD40, RFD90), Fixed Reader (Zebra FX7500, FX9600), and Printer (ZD621R, ZT411, ZT620).

Zebra MC333X/MC339X is a mobile RFID reader that is easy to carry because it is the lightest of its kind and made for easy one-handed use, both for right-handed and left-handed workers. It has a 35% larger battery capacity to accommodate field operations in 1 shift.

Zebra FX7500/FX9600 is a fixed RFID reader that can be fixed to the reading points. This reading point can usually be on the conveyor, gate, intermediate area, and others. This Fixed Reader will read every RFID tag that passes through it and send this information quickly and accurately to the server/data processing for recording transactions.
