RFID transponders, also known simply as RFID tags, are devices that can be attached to an item in order to track its movement and location. They generally contain a small RFID chip with an antenna and are used in a variety of applications, such as product inventory tracking and asset management. The PCF7939MA/LABC08SP is one such RFID transponder. It is a smart card compliant with ISO/IEC 14443 type A. This article will discuss the application field and working principle of this RFID transponder.

The PCF7939MA/LABC08SP is well suited for a variety of applications. It is particularly well-suited for applications in the transportation industry, such as ticketing and fare collection systems, toll systems, and vehicle identification systems. Additionally, it is used in access control systems, inventory tracking systems, and other applications requiring contactless authentication and identification. It is perfect for applications where a long range is required, as it has a reliable read range of up to 10cm.

In terms of functionality, the PCF7939MA/LABC08SP is capable of transmitting and receiving data. It features an EEPROM with 64 bytes, which can be used to store data. Additionally, it supports authentication and privacy features, allowing it to be used for secure applications. It also features a unique ID number that can be used to identify a tag.

The PCF7939MA/LABC08SP works by receiving an electromagnetic signal from an RFID reader. The reader sends out an energy signal that transmits encoded information to the antenna of the RFID tag. The tag then interprets this signal and sends it back to the reader in the form of a digital response. This allows the tag to identify itself and communicate with the reader. The tag can then send data back to the reader, such as its unique ID number.

In addition to its RFID capabilities, the PCF7939MA/LABC08SP also has a contactless payment system built-in. This allows it to be used for contactless payments, such as using a mobile phone to pay for goods and services. It supports all major payment protocols, such as MasterCard Mobile, Visa Ready, and Apple Pay.

The PCF7939MA/LABC08SP is a versatile radio frequency identification tag that can be used in a variety of applications. Its long range and secure authentication features make it ideal for a wide range of applications. From contactless payments to access control, this tag is a great choice for many different RFID applications.
