What Is The Size Of The RFID Card In Inches?

RFID (Radio Frequency Identification) cards are becoming increasingly popular in various industries due to their ability to store and transmit data wirelessly. These cards come in different shapes and sizes, but what is the standard size of an RFID card in inches?

The most common size for an RFID card is 3.375 inches by 2.125 inches, which is the same size as a standard credit card. This size is known as CR80, and it has become the industry standard for most applications.

However, there are other sizes available for RFID cards depending on their intended use. For example, some RFID cards used for access control may be smaller than the standard CR80 size, while others used for inventory management may be larger.

It's important to note that the size of an RFID card is not the only factor that determines its functionality. The frequency range, antenna design, and memory capacity are also crucial components that affect its performance.

In conclusion, the standard size for an RFID card is 3.375 inches by 2.125 inches (CR80), but there are other sizes available depending on their intended use. When choosing an RFID card, it's important to consider not only its size but also its other features to ensure it meets your specific needs.
