How To Identify RFID Card Frequency?

---

How to identify RFID card frequency is a question that many people who use or deal with RFID cards may have. RFID stands for radio frequency identification, which is a technology that uses electromagnetic fields to identify and track objects that have RFID tags attached to them. RFID cards are a type of RFID tag that can store information and communicate with RFID readers. RFID cards are widely used in various applications, such as access control, payment, identification, transportation, etc. However, not all RFID cards are the same. They can operate at different frequencies, which affect their performance, range, and compatibility. Therefore, it is important to know how to identify the frequency of an RFID card before using it or buying a suitable reader for it. In this blog post, I will introduce three methods to identify the frequency of an RFID card, and recommend some products that can help you with this task.

1. The first method is to use a smartphone app that can scan and read RFID cards. There are many apps available for both Android and iOS devices that can do this, such as NFC Tools, NFC TagInfo, NFC Reader, etc. These apps can use the NFC (near field communication) function of your smartphone to scan and read RFID cards that operate at 13.56 MHz, which is the most common frequency for NFC cards. However, these apps cannot read RFID cards that operate at other frequencies, such as 125 kHz or 860-960 MHz. Therefore, this method is only suitable for identifying NFC cards or high frequency (HF) cards. To use this method, you need to download and install one of the apps on your smartphone, then open the app and follow the instructions to scan your RFID card. The app will display the information of your card, such as the type, serial number, memory size, etc. It will also show you the frequency of your card, which is usually 13.56 MHz for NFC cards.

If you want to use this method, I recommend you to try the following products:

• NFC Tools: This is a free app that can read and write NFC tags and cards. It can also perform various tasks based on the information of your card, such as opening a URL, sending a text message, launching an app, etc.

• NFC TagInfo: This is another free app that can read NFC tags and cards. It can also show you detailed information about your card, such as the manufacturer, standards, features, security status, etc.

• NFC Reader: This is a simple and easy-to-use app that can read NFC tags and cards. It can also copy the data of your card to another NFC tag or card.

2. The second method is to use a dedicated RFID card reader that can detect and display the frequency of your card. There are many types of RFID card readers available in the market that can support different frequencies and standards of RFID cards. Some of them can also read multiple frequencies at once, which is very convenient for identifying the frequency of your card. To use this method, you need to buy an RFID card reader that matches your needs and budget, then connect it to your computer or smartphone via USB or Bluetooth. Then you need to install the software or app that comes with your reader or download it from the official website. After that, you need to launch the software or app and follow the instructions to scan your RFID card. The software or app will show you the information of your card, including the frequency.

If you want to use this method, I recommend you to try the following products:

• RFID Card Reader: This is a versatile and affordable reader that can support 125 kHz and 13.56 MHz RFID cards. It can also read ISO14443A/B and ISO15693 standards. It has a USB interface and comes with a software CD.

• RFID/NFC Reader Writer: This is a powerful and multifunctional reader that can support 125 kHz, 134 kHz,
