RFID technology is being widely applied in most large-scale enterprises and factories at home and abroad. The foundation of the RFID system’s success lies in the RFID card. So what are the criteria for choosing the right RFID card? The following article by IT Nam Viet will help you answer this question in detail.
The Importance of Choosing the Right RFID Tag for Your Needs
In fact, RFID is a technology that uses electromagnetic fields to automatically identify and track tags attached to objects. It is a fact that businesses that are just starting to deploy RFID often focus on card readers and management software, but ignore how to choose the right RFID tag.
With more than 10+ years of experience in providing comprehensive RFID technology, IT Nam Viet feels that choosing the wrong RFID card and not suitable for the business can lead to the following serious consequences:
- RFID tags that are not suitable for the environment or materials to be tagged will reduce the success rate of reading, cause interference or slow down the reading speed.
- Choosing low-quality RFID cards or choosing RFID cards that are too expensive compared to the requirements will increase the initial RFID cost, which causes difficulties for businesses, especially small-scale units.
Choosing the right RFID card for the business’s needs will help the system to be easily upgraded later, optimizing time and cost effectively. If you need advice on RFID cards of all kinds, please contact IT Nam Viet via Hotline (+84) 962 888 179, we are ready to serve you 24/7.
Criteria for Choosing the Right RFID Card That Everyone Needs to Know
RFID cards come in many varieties, including low-frequency RFID cards, high-frequency RFID cards, ultra-high-frequency RFID cards, passive RFID cards, active RFID cards, semi-active RFID cards, etc. Although RFID cards are manufactured according to international standards, not all cards are of the best quality.

Below are the criteria for choosing the right RFID card for each business that you should refer to:
Understanding the Basics of RFID Tags
Understanding RFID tag materials is important for choosing an RFID tag. An RFID tag consists of an RFID chip, an antenna, and a substrate. Depending on the type of tag, the chip can be passive (no battery, receiving power from high-frequency radio waves emitted by an RFID reader) or active (with a self-powered battery to transmit data).
One of the factors that greatly affects the performance of RFID tags is the RFID frequency range. Accordingly, there are 3 RFID frequency bands commonly used in most fields, which are:
- Low Frequency RFID (LF): 125 kHz – 134 kHz
- High Frequency RFID (HF): 13.56 MHz
- Ultra High Frequency RFID UHF 856 MHz – 960 MHz
To better understand these frequency bands, please visit our following article: “Overview of RFID Frequency – How to Choose the Right RFID Frequency for Your Business“.
Consider the operating environment of the RFID system
Before deciding to choose an RFID tag for the operation of a business, factory, organization, agency, etc., you need to determine the operating environment, which means you must know where the RFID label is used, what the location is, what the temperature and humidity conditions are, etc. This information will be the basis for you to make the appropriate choice, meeting the usage requirements and optimal durability for the system.
Note on the tagged object
Which tracking object will the RFID tag be attached to? This is a very important question to help you find the right tag. In fact, UHF RFID tags are usually not recommended for use in metal or liquid environments, because the tag will be interfered with, hindering the reading and identification of the object. Instead, in this environment, LF RFID tags will be preferred.
Of course, not only in terms of operating environment, RFID tags may not be read for many other reasons. To know more about this, you can refer to the following article of IT Nam Viet: “Summary of Reasons Why Readers Cannot Read RFID Chips“.
Based on the factors of read/write distance
Each type of RFID card will meet different requirements for read/write distance. Therefore, you need to clearly define the minimum and maximum read/write distance you want, moreover, you also need to determine the location of the RFID reader installation, using a fixed RFID reader or a handheld RFID scanner,…
On the other hand, what data requirements do you need, what information needs to be stored on the card, how much memory capacity, is the card read-only or includes read-write features, how often does data write, etc. Answering all these questions will help you consider and choose the type of RFID card that suits your needs.
In fact, if you are a new business unit, without much experience in deploying RFID systems, it is best to seek advice from a reputable RFID card and technology supplier, they will be the ones to give you the most optimal solution.
Choose RFID tags with suitable shapes and sizes
Depending on the characteristics of each object tagged with RFID and the way of tagging, you should consider and choose tags with corresponding shapes and sizes, ensuring the most optimal reading performance. Accordingly, some of the most popular RFID tag shapes include RFID labels, hard tags, hang tags, RFID keychains, RFID bracelets, etc.
Based on investment budget
Depending on the scale of the project, you need to survey and carefully calculate the number of RFID cards, investment budget, etc. to choose the appropriate cards as well as readers, RFID software, etc., ensuring functionality and optimizing costs.
Research and choose a reputable RFID card supplier
This is one of the key factors for the success of the project. You need to research and choose a reputable RFID card supplier to get thoughtful sales, return and after-sales policies. An RFID card processing unit with many years of experience and trust from customers will be worthy of your “trust”, peace of mind when using the system.
