What are the components of RFID inventory tracking?

1. RFID Tag

RFID tags are wireless devices that consist of a microchip and a small antenna. These tags often attach to or are embedded in products or packaging to store digital information about the item. RFID readers, with sending and receiving antennae, communicate with the RFID tag to collect data. The reader then sends this information to a computer software system, which processes the data to track inventory in real-time. 

The advantages of using RFID tags for inventory management include the ability to read tags remotely, read multiple tags at once, and track individual products with unique identification codes. RFID tagging can be used for stock control, stock security, and quality control. The costs of using RFID tagging have decreased in recent years, making it an attractive option for retailers, wholesalers, distributors, and manufacturers.

2. RFID Reader

RFID Reader is either a portable device or “fixed reader” that uses a radio-frequency signal generator to generate radio waves and transmit signals to activate and detect information from RFID tags. It has or attached to one or more antennae that send and receive signals back from RFID tags. The reader is controlled by a microcontroller and is mainly of two types: fixed readers and mobile readers. 

3. Passive Tags

Passive RFID tags are used for inventory tracking and are powered by the reader’s electromagnetic energy. They are economical in supply chain management for access control and file tracking. Passive tags come in two forms: hard tags and inlays. The inlay is the part of the tag that encodes the data, and it has an antenna attached to it. 

The reader, also known as an interrogator, sends an electromagnetic signal to the antenna, which powers the inlay and allows it to transmit data back to the reader. The two types of antennas used with passive RFID tags are near-field antennas that have a short read range of a few inches, and far-field antennas that have a longer read range of up to 300 feet with 10-30 feet being the standard application. 

The UHF 915 MHz FR4 High Temperature RFID Tags are designed to be applied to assets, servers, pallets, or attachment to rigid items and are adept in surviving high temperature RFID applications. These tags have a low profile and are made of a PCB/FR4 material. They are used for inventory tracking and are capable of surviving in harsh environments. They are also designed to withstand high temperatures of up to 200°C. 

The tags are equipped with a UHF 915 MHz transponder that provides a read range of up to 7 meters. The FR4 tags can be mounted on metal surfaces and are available in a variety of sizes. These tags are ideal for use in logistics and inventory management. They are also suitable for tracking boxes, cartons, and pallets. In addition, they can be used for security purposes. The UHF 915 MHz FR4 High Temperature RFID Tags are reliable and durable, making them a popular choice for inventory tracking.

High Frequency (HF) RFID tags are designed to read and write to transponders fitted to HellermannTyton RFID cable ties and accessories. They offer a read range of up to 1 foot and a data transfer rate of up to 424 kbps. There are passive and active HF RFID tags. Passive HF tags do not have an internal power source and rely on the energy emitted by the reader to power the tag. Active HF tags, on the other hand, have their own power source and can transmit data over longer distances.

HF tags are commonly used in inventory management for item-level tracking. They improve inventory accuracy by allowing for real-time monitoring of stock levels and reducing the risk of errors that can occur with manual tracking methods. Additionally, HF tags can automate the check-in and check-out process of items, reducing the time and labor required for inventory management.

4. Low Frequency (LF) Tag

Low Frequency (LF) RFID tags operate at a frequency of 125 kHz and are commonly used in logistics and inventory management. LF tags are ideal for applications that require close-range reading and have a read range of less than 10 cm. These tags are often used in the tree identification, box, carton, pallet tracking, and security industries. LF tags are preferred in harsh environments because they operate in extreme temperatures and resist interference from metal and liquids. 

For instance, LF Tank RFID Tags are designed for curved surfaces and apply to gas cylinders. In the automotive industry, LH tags can track vehicles on the production line and to monitor the movement of goods in warehouses.


5. UHF Tag

UHF RFID tags, also known as RAIN RFID tags, are radio frequency identification tags that operate in the ultra-high frequency range of 860-960 MHz. These tags are used for automatic identification and tracking of objects in retail, manufacturing, logistics, and warehousing. UHF RFID tags offer long read range, high accuracy, and fast data transfer rates.

In inventory management, UHF RFID tags track and manage inventory levels. They attach to items, pallets, or containers, and are read by RFID readers to collect data on the location, movement, and status of inventory items. UHF RFID tags are particularly useful in industries that deal with high volumes of inventory, such as retail and manufacturing.

For example, in retail, UHF RFID tags track inventory levels and prevent stockouts. In manufacturing, UHF RFID tags track the movement of raw materials and finished products, and ensure that the right materials are used for production. In logistics, UHF RFID tags track the movement of goods across the supply chain, and ensure that they are delivered to the right location at the right time.

6. NFC Tag

NFC (near-field communication) is a type of RFID technology that allows for two-way communication between devices. Unlike traditional RFID tags, which only allow for one-way communication, NFC tags can both send and receive data. NFC is commonly used for short-range communication, with both devices within inches of each other. 

In inventory management, NFC tags are often used for card emulation with contactless payment methods like Apple Pay. Engineers can also use NFC technology to communicate with RFID cable ties on valuable equipment, allowing for easy tracking and inventory management.


7. WiFi Tag

Compared to other types of RFID tags, the WiFi Tag has a longer range, allowing it to transmit data over a greater distance. Additionally, the WiFi Tag transmits data in real-time, providing up-to-date information on inventory levels. 

Industries that commonly use the WiFi Tag for inventory management include retail, healthcare, and manufacturing. In retail, the WiFi Tag tracks inventory levels and ensures that products are always in stock. In healthcare, the WiFi Tag tracks medical equipment and ensures that it is always available when needed. In manufacturing, the WiFi Tag tracks raw materials and finished products, ensuring that inventory levels are always optimized.

8. iBeacon

iBeacon technology is a Bluetooth Low Energy (BLE) wireless protocol that provides precise location-based information and proximity tracking. When BLE is used with RFID tags, iBeacon technology enhances the functionality of RFID tags by providing more accurate and real-time location data. This can be particularly useful in industries such as retail, where inventory management is critical. 

For example, a retailer can use iBeacon-enabled RFID tags to track the movement of products in a store and provide customers with personalized recommendations based on their location. Another example is in healthcare, where iBeacon technology can track the location of medical equipment or patients in a hospital.

iBeacon-enabled tags provide more precise location data than RFID tags alone, with accuracy up to a few centimeters. iBeacon technology can also work in areas with poor GPS signal, making it ideal for indoor tracking. However, a potential drawback of using iBeacon technology is that it requires additional hardware and software to be installed, which can increase costs and complexity.


9. QR Codes

QR codes are two-dimensional (2D) codes that can hold more data than traditional barcodes. They can be found on clothing tags, restaurant menus, and other products. Unlike RFID tags, QR codes are visual and can be scanned using a smartphone or tablet. 

QR codes are a good choice for inventory management in scenarios where cost is a concern because they are inexpensive to print and easily scan with a smartphone. They also track items that do not require constant monitoring, such as office supplies or non-perishable goods.

10. Chip Tag

The Chip Tag is a type of RFID tag containing a microchip and a small aerial that holds digital information about a specific item. It is encapsulated in plastic, paper, or a similar material and attached to the product, packaging, pallet, container, or delivery truck. The Chip Tag is read remotely by an RFID reader, which transmits and receives radio signals to and from the tag. The information collected by the reader is collated and processed using specialized software. 

The Chip Tag offers several benefits over other inventory management methods such as barcodes, including the ability to read multiple tags at once, track individual products, and update information. However, creating an RFID management system is a significant investment due to the high cost of the Chip Tag’s microchip and the RFID reader. As a result, it may not be cost-effective for some businesses.

                    5. Barcode tags: Up to an inch

                    While barcodes are common in retail settings, their range is limited compared to RFID tags. Barcodes can only be scanned one at a time and require complete visibility. In contrast, RFID tags don’t need to be in sight of a reader and have a larger read range. 

                    6. HF RFID tags: Up to 3 feet

                    HF RFID tags have a maximum distance coverage of up to 1 foot (30 cm). However, the typical range of HF RFID tags is around 4-5 inches (10-12 cm). The performance of HF RFID tags can be affected by various factors: the presence of metal or water, interference from other electronic devices, and the orientation of the tag and reader. The type of antenna used can also impact the range of HF RFID tags.

                    Steps how to use RFID tags for inventory management?

                    Step 1: Selecting an RFID tag

                    When selecting an RFID tag for inventory management, there are a few factors to consider. First, determine the read range needed. Active tags have a range of over 100 meters while passive tags can range from a few inches to 100 meters with 10 meters being the typical application. Second, consider the frequency needed. Low frequency (LF RFID) is best for short-range applications, high frequency (HF RFID) for mid-range, and ultra-high frequency (UHF RFID) for long-range. 

                    Third, decide whether a semi-passive or passive tag is best. Semi-passive tags have a battery to extend communication range, while passive tags rely on electromagnetic energy from the reader. Passive tags are low-cost and have a long shelf life, but are best for situations where they won’t be reused. Finally, consider the size and weight of the tag. Passive tags are small and light, making them ideal for use in inventory management.

                    Step 2: Get license and testing kit

                    Some providers will provide you a test environment to test your RFID tags, and inventory solution. There is a free test environment ofr up to 150 assets available at https://z.assetvue.com

                    Step 3: Install the transponder reader

                    To install a transponder reader for RFID inventory management, you need the RFID reader itself, a computer or database system to interface with the reader, and RFID cable ties or accessories fitted with HF transponders. The physical placement of the reader is crucial for optimal performance. It should be placed in an area with minimal interference from other radio waves and in close proximity to the items being tracked. 

                    The reader should be connected to a power source and the computer or database system. Additional steps for proper installation may include configuring the reader’s settings and software to match the desired inventory management system and ensuring that the transponders are properly programmed and attached to the items being tracked. 

                    Step 4: Set up an inventory management system

                    To set up an inventory management system using RFID tags, you need an RFID generator, printer, scanner, and portal track software. Each item must have an RFID label attached to it, which will replace the barcode. However, the barcode should not be blocked, as there may be exceptions. Both mobile and fixed readers can be installed on site, with mobile readers used to perform a search for items and fixed ones reading products as they come within the vicinity of certain points of the facility.

                    To integrate the RFID tags with the inventory management system, you need to tag everything, which is a significant job but necessary for effective asset management and reducing shrinkage. Once tagged, the items will be automatically tracked in your inventory management system. 

                    Step 5: Start using RFID tags

                    Once you have your tags, you need to set up your RFID reader and antenna to accurately collect data from the tags. You may also need to encode your tags with relevant data, such as product information or location data.
