Everything You Should Know About RFID Tags

Take a look at the label on the bottle of alcohol you buy, intended to discourage theft, or the small sticker on the car's windshield that permits fine-free toll roads; these both include RFID tags. While the majority of RFID tags are used to identify products or track packages, they are also utilized to identify the health of patients or pets in hospitals.

What are RFID tags, and what are they used for?

RFID tags can be described as a form of tracking system that makes use of radio waves to find, track, and even communicate with objects and individuals. In essence, RFID tags are smart tags that are able to contain a variety of information, from serial numbers to brief descriptions and even entire pages of information. Certain RFID tags come with security features, such as cryptographic encryption, for the highest level of verification and security. RFID tags are typically recognized by their radio frequency, which includes low frequency (LF) as well as high frequency (HF) or ultra-high frequency (UHF).

The frequency range of LF systems is 30 to 300 kHz, with a read range of up to 10 centimeters. These systems are typically employed in applications such as access control and monitoring livestock.

The HF systems operate between 3 and 30 MHz and have a read range of 10 centimeters to one millimeter (3 feet). These systems are often employed for electronic ticketing and payments as well as for the user experience.

UHF systems can operate between 300 MHz and 3 GHz and read ranges that extend to 12 meters (39 feet). They are the ones typically employed in the fields of retail inventory tracking, garages for parking, door access, and asset administration.

Passive vs. Active RFID Tags

There are two kinds of RFID tags: active and passive. Passive RFID tags tend to be more popular as they don't require an immediate line of sight to the reader; however, they do offer a significantly shorter reading range and are lighter and smaller in size. Passive RFID tags are perfect for:

Uses of RFID tags

1. Management of inventory and supply chain

2. Personnel and asset tracking

3. Logistics

4. Manufacturing and Industrial

5. Protection of brands and counterfeiting

6. Real-time location systems (RTLS) using 3D orientation-insensitive design

7. Access control for gates and perimeters

8. Healthcare and pharmaceutical

9. Travel and entertainment

10. Retail and apparel

 Active RFID tags are not as common as they require their power source and transmitter source. They are typically larger, tougher, and more durable, and they cost more. A beacon that can be used to monitor RTLS continuous medical monitoring or theme park admission is an example of an active RFID tag.

What is NFC technology? HF RFID

As part of HF RFID, near-field communication (NFC) technology can be used to connect to the Internet of Things (IoT) and allow for more secure and complex interactions. The communication between the NFC tag and the object may go in both directions, making everyday objects more intelligent and more secure. NFC is limited to high-frequency and close proximity, as well as the use of only one NFC tag at a time.NFC is extremely easy to use, and as most mobile phones are NFC-equipped, it usually doesn't require additional infrastructure in order to utilize the technology.


There are several benefits of RFID tags, like RFID tags let businesses effectively run their operations with minimal cost and positive outcomes. There are a variety of options available, such as physical cards for access as well as inlay labels, tags, or touchless solutions.
