Are All RFID Cards The Same?

RFID technology has revolutionized the way we track items and exchange information. But are all RFID cards the same? The answer is no. These RFID cards can be classified into different types according to their frequencies, such as 125KHz RFID cards, 13.56MHz RFID cards, and UHF RFID cards, we can also according to the unique features and uses.  Let’s take a closer look at some of them.

• RFID Plastic Card

The RFID Plastic Card is a common type of RFID card that you might come across in everyday life. These cards are made of durable plastic and contain an embedded RFID chip that can store and transmit information. They are divided into 13.56MHz RFID Card, 125MHz RFID Card, 860~960MHz UHF RFID Card. They are often used for access control, identification, traceability and payment applications.

• Dual RFID Card

A Dual RFID Card is a special type of RFID card that contains two RFID chips, each operating at a different frequency. This allows the card to be compatible with multiple systems, increasing its versatility. For example, one chip could be used for building access control, while the other could be used for public transportation.

• Passive RFID Card

The Passive RFID Card is another common type of RFID card. Unlike active RFID cards, which have their own power source, passive cards are powered by the reader’s electromagnetic field. This makes them cheaper and smaller than active cards, but also limits their range.

• Active RFID Card

On the other hand, an Active RFID Card has its own power source in the form of a battery. This allows it to broadcast its signal over a much larger range than passive cards, making it ideal for tracking assets over large areas.

In conclusion, while all RFID cards use similar technology to store and transmit information, they are not all the same. Each type of card has its unique features and uses, making them suitable for different applications.
