How To Determine What Kind Of RFID Card You Have?

We begin with a pretty basic method: turn on the flashlight on your phone, place it on the back of the card, and examine the chip’s design. As illustrated in the diagram below, the shape and frequency of the chip correspond one-to-one.

Furthermore, if the card is a high-frequency chip card, you can usually scan it with the taginfo APP to acquire the precise chip model, however this APP is only available for Android phones with NFC capability.

It is a fact that radio frequency identification (RFID) technology is everywhere wherever you go. You can find its use in your everyday lives, from hotel access control systems, and car parking systems to logistics maintenance. However, with regular updates and advancements in technologies, it is becoming difficult to determine what kind of RFID Card you have in your industry until you didn’t get into the RFID technology.

There are a host of options and technologies available that provide secure access. However, the seemingly endless option can leave you scratching your head. To avoid this confusion, you need to gain an in-depth understanding of the different types of RFID technology, specifications, and features and then make the best use of it

Steps To Determine The Type Of Technology You’re Using

There are a couple of steps that will help you determine the type of technology. These steps include:

  • You need to scan the card through your android phone. If it scans, then it is an NFC (Near-Field Communication) contactless card that enables short-range communication between compatible devices. This technology evolved from RFID and is based on the RFID protocol standards. It is more valuable in making contactless payments via mobile wallets. NFC provides a quick and safe way for consumers to pay while saving them from the rush and cash payment hassle.
  • The next way to determine the type of card is by checking the UID number which is printed on the card. If the UID number starts with three or four zeros, then it is an RFID Card that uses electromagnetic fields to automatically identify and track the RFID tags.

Frequency Of RFID 

Advanced technology embedded RFID smart card works on a certain frequency level to communicate the data. Based on the frequency, RFID technology is divided into three broad categories. 


  • Low Frequency (LF) – RFID tags of low frequency generally operate in the range of 30 kHz to 300 kHz (usually at a frequency of 125 kHz). Such a tag has a read scope of 10 cm which is shorter than other frequencies. As it has a slower data reading frequency, LF RFID cards can operate better in the presence of metals and consist of features like the ease and safe access control.
  • High Frequency (HF) –It covers the range from 3 MHz to 30 MHz, with most applications working at 13.56 MHz. It has a reading scope of between 10 cm and 1 m. HF embedded RFID is ideal for electronic ticketing, smart card payment, data transfers, and access security systems.
  • Ultra-High Frequency (UHF)– As the name sounds, the frequency range of UHF RFID tags is between 860 MHz and 960 MHz, which is higher than any other RFID frequency tag. It is known for its extreme capabilities for faster data transfer rates with a reading range of 12 m. 

Now you may have a basic understanding of RFID technologies and their different frequency range, it will become easier for you to identify the RFID card and the frequency it holds. With RFID technology continuing to expand, it’s high time that you must make the best use of this ever-growing smart technology.
