Handheld RFID: Definition, Function, Components, and Applications

In the era of supply chain digitalization, the need for automatic identification devices is increasing. Companies are no longer limited to RFID gates or fixed antennas installed permanently in warehouses; they also require more flexible solutions for field operations.

This is where Handheld RFID comes in as a portable device that facilitates quick and accurate identification, inspection, and asset tracking. Its flexibility makes this technology a key choice in a variety of industries, from retail to transportation.

Understanding Handheld RFID

Handheld RFID is a portable device that functions to read and write data on RFID tag Mobile. Its shape resembles a handheld scanner or rugged smartphone with a built-in antenna, making it easier for users to identify items without having to be at a fixed point like gate or fixed antennas. This technology is very useful for field operations such as inventory, inspection, and asset audits because it is flexible and easy to use.

Handheld RFID Function

Handheld RFID plays a crucial role in supporting operational efficiency. These devices enable warehouse staff or field officers to perform stocktaking, track items, and verify data in real time. Because they are mobile, handheld RFID can also be used in areas difficult to reach by fixed antennas, such as high shelves, outdoor areas, or storage locations with complex layouts.

Handheld RFID Components

In order to work optimally, handheld RFID usually consists of several main components:

1. Internal Antenna

Functions to capture and transmit radio signals to RFID tags. This antenna is what allows the device to read or write data wirelessly.

2. Reader Module

It is the brain of the device that processes signals from the antenna and then translates them into digital data that can be read by the system.

3. Screen and Operating System

Used to display reading data while running inventory management applications or integration with other systems.

4. Battery

Providing power for mobile operations with large capacity, usually designed to withstand full day use in the field.

5. Connectivity

Includes Wi-Fi, Bluetooth, or 4G/5G so that the read data can be directly sent to the server, ERP system, or WMS in real time.

Advantages of Handheld RFID

Compared with barcode scanner And antena fixed, handheld RFID has a number of advantages:

1. High mobility

Not limited to a specific point, the handheld can be carried anywhere making it ideal for field inspections or audits.

2. Fast reading without line of sight

Unlike barcode scanners that must be aligned with the label, handheld RFID can read tags without direct visual contact.

3. Ability to read multiple tags

In a single scan, handheld RFID can read tens to hundreds of tags at once, speeding up stocktaking compared to barcodes.

4. More flexible than fixed antenna

Fixed antennas only read tags at certain points, while handhelds can follow the operator to reach areas not covered by the antenna.

Disadvantages of Handheld RFID

Despite its advantages, handheld RFID also has limitations when compared to barcode scanners or fixed antennas:

1. Price is more expensive than barcode scanner

The initial investment of handheld RFID is relatively high, especially for small businesses.

2. Limited range compared to fixed antenna

While fixed antennas can monitor a wide area automatically, handhelds still require an operator to carry the device.

3. Operator dependency

The effectiveness of handhelds depends on the discipline of staff in using them, in contrast to fixed antennas which work automatically.

4. Battery power

Because they are mobile, handheld RFIDs require periodic charging to ensure uninterrupted operation.

Handheld RFID Applications in Various Industries

Handheld RFID is used in various vertical industries with specific roles:

1. Retail

Helping with stocktaking, checking the availability of goods on shelves, and tracking products to reduce shrinkage.

2. Logistics & Warehousing

Facilitates the inbound and outbound process of goods with fast verification, and helps with regular cycle counts.

3. Manufacturing

Supports component recording on production lines and inspection of assets that are not reachable by fixed antennas.

4. Healthcare

Used to track medical devices, medicines and verify pharmaceutical stocks quickly.

5. Transportation

Handheld RFID makes it easier to check passenger baggage and even monitor logistics at ports or airports.

Conclusion

Handheld RFID is a portable device that facilitates the rapid and accurate identification and tracking of goods without direct visual contact. Its versatility makes it highly useful in warehouses, manufacturing, and public services.

Compared to barcode scanners or fixed antennas, handheld RFID offers advantages in mobility and the ability to read multiple tags simultaneously. However, shorter range, implementation costs, and operator dependence still need to be considered.
