NFC vs. RFID: What’s the Difference?

nfc or rfid the answer depends on your needs [Music] rfid and nfc are two technologies used for wireless data transmission rfid or radio frequency identification is a wireless method by which items can be uniquely identified using radio waves an rfid system consists of a scanning antenna a tag and a reader nfc or near field communication is a subset within rfid technology that allows devices to wirelessly share data using high frequency short range radio waves nfc enhances rfid and contactless capabilities by allowing devices like smartphones to perform more dynamically to take advantage of the billions of rfid tags and terminals already deployed all modern phones now accept nfc chips and applications such as apple pay and google pay as with any technology there are also risks to using touchless data exchange which you can read about in the link above or in the description below while rfid and nfc are similar there are some major differences between the two technologies rfid can be used over long distances while nfc is limited to close range proximity this makes rfid perfect for location tracking while nfc works well for secure communications like contactless payments nfc is capable of two-way communication such as peer-to-peer mode between two devices rfid communicates in one direction from the tag to the reader rfid can only carry simple id information while nfc has a larger storage space and can hold and transmit several types of data rfid is generally used for identification because its scanning capabilities can reach hundreds of feet rfid is able to scan and read many tags at the same time which is great for inventory tracking and supply chain management nfc is geared more towards communication often requiring close contact user interaction and handling of the device such as scanning a qr code for information or data sharing in the end the answer for which technology is better depends on how they're used how do you use rfid or nfc in your daily life leave your thoughts in the comments below and be sure to hit that like button too you
