What is a hard RFID tag?

Introduction to RFID technology

RFID (Radio Frequency Identification) is a technology that identifies objects using radio waves and is part of the automatic identification and data capture (AIDC) family. This technology allows businesses to quickly and efficiently identify, track, and manage assets, goods, or people.

An RFID system consists of three main components:

RFID tag: contains a microchip and antenna to store data and transmit signals.
RFID reader: receives the signals from the tag and converts them into usable data.
RFID antenna: transmits and receives radio signals between the tag and the reader.

RFID technology operates at various frequency bands, with the most common being:

Low Frequency (LF): 125 kHz
High Frequency (HF): 13.56 MHz
Ultra High Frequency (UHF): 860–960 MHz

Each frequency band is suited for different applications and reading distances.

What is a hard RFID tag?

A hard RFID tag is an RFID tag encased in a durable plastic shell, designed to withstand impacts, high temperatures, moisture, and chemicals—ideal for use in harsh industrial environments.

Basic structure

A standard RFID tag includes:

RFID inlay (consisting of a microchip and antenna)
Protective casing made of ABS plastic or similar durable materials
Mounting options: adhesive, screws, welding, or cable ties depending on the application

Classification by power source

Active RFID tag: contains an internal battery, capable of transmitting signals up to 100 meters. Often used to track high-value assets or vehicles.
Passive RFID tag: no internal power source, transmits signals through electromagnetic induction when near a reader (typically 1–12 meters). Commonly used for inventory and warehouse management.

Classification by mounting surface

On-metal tags: designed to be mounted on metal surfaces
Off-metal tags: for non-metallic surfaces

Key advantages of hard RFID tags

Superior durability: Performs reliably in extreme environments, including exposure to dust, water, high temperatures, or industrial chemicals.
Contactless readability: Unlike barcodes, RFID tags don’t require direct line-of-sight for scanning, allowing faster workflows.
Automation of processes: Reduces human error and increases operational efficiency by integrating into automated systems.
Long-term cost savings: While initial investment is higher than barcodes, RFID minimizes product loss, theft, and labor costs over time.
High customizability: Available in various shapes, sizes, and materials to meet specific industry requirements.

Real-world applications of hard RFID tags

Automotive manufacturing

Tags are attached to components and vehicles on the assembly line to track assembly progress in real time.

Construction sites

Tags are affixed to tools and equipment to manage check-in/check-out processes, prevent loss, and monitor usage.

Access control

Used in parking facilities and gated entry systems to track vehicle entry and exit or employee access within production areas.

Logistics and supply chain management

Tags are mounted on pallets, boxes, or containers to monitor location, transportation, and product conditions.

Healthcare and medical services

Used to manage medical equipment, track consumables, secure patient records, and enhance safety in hospitals.

Frequently asked questions about hard RFID tags

Question 1: What are RFID tags used for?

They are used to identify, track, and manage assets, control access, support supply chains, and monitor operations in modern systems.

Question 2: How many types of RFID tags are there?

By power source: active and passive tags
By frequency: LF, HF, UHF
By environment: metal-mount, waterproof, heat-resistant tags

Question 3: What is the lifespan of an RFID tag?

Passive tags can last 10–15 years if not physically damaged.
Active tags have a battery life of 3–7 years, depending on usage.

Question 4: Can RFID tags be counterfeited?

It’s extremely difficult, as each tag contains a unique identifier, especially when combined with secure software authentication.

Considerations when choosing a hard RFID tag

Operating environment: temperature, humidity, impact exposure
Mounting surface: metal vs. non-metal
Reading range: short or long distance
Compatible reader type: fixed or handheld reader

Selecting the right hard RFID tag maximizes your investment and operational efficiency.
