Near Field Communication (NFC) technology has become increasingly popular in recent years, particularly for payment transactions and data sharing between devices. However, as the technology continues to evolve, it is becoming apparent that NFC antennas have other practical uses beyond just these applications. From healthcare to retail and beyond, NFC antennas are set to revolutionize the way we interact with everyday objects and systems. In this article, we explore some of the innovative uses of NFC antennas and their potential impact on various industries.
The NFC chips are becoming more prevalent, as are the antennas required for their operations. Due to the fact that many NFC-enabled objects are disposable, [Brother-live] is exploring the possibility of repurposing the antennas. He has been able to extract the antennas from used metro cards and conduct experiments using them. These antennas are flexible PCBs with tracks forming a coil around the outside, which can be cleaned and soldered to for connection purposes. In the video below, [Brother-live] demonstrates the rather limited functionality of the antennas, including their usage in a low-quality heating pad, as a power harvesting antenna from NFC readers, and as the coil of a moving-coil speaker, which may have some promise with further development. If you are interested in learning more about NFC cards, this subject has been previously covered.
In conclusion, NFC antennas are versatile and can be used in a variety of applications beyond mobile payments. From access control to inventory tracking, these antennas have become a critical component of many industries. With the rise of the Internet of Things, the use cases for NFC technology will only continue to expand. As consumers and companies alike continue to embrace the convenience and benefits of NFC technology, the possibilities for NFC antennas are endless. So, if you’re looking to streamline your business processes or simply enhance your daily life, consider the power of NFC antennas.
