We have been getting many question regarding communication system to know what NFC is and how it’s different than Bluetooth. Keeping that in mind we will try to explain the differences between NFC and Bluetooth starting with a brief history then moving onto their current status and future. We will also mention their Advantage and Disadvantage and try to make it as understandable as possible.
NFC (Near Field Communication):
Radio frequency identification (RFID) was the base upon which Near Field Communication (NFC) started back in the 80’s. This technology permitted the user to direct radio information to a receiver where it was recognized. The initial form of this technology was used for tracking and security purposes at retail locations. As time progressed so did this technology, and the two strong companies NXP semiconductors and Sony came to invent NFC or “Near Field Communication” in 2002. In 2010 this technology evolved and got incorporated in Android smartphones.
Basically NFC is a data transfer technology that works at a short distance or another way to put it is that it’s a sort of extremely short range wireless-communication. By a process called inductive coupling two compatible devices can transfer the data in the form of beam. For NFC to work both devices should be at distance of no more than 4 centimeters for data transfer to effectively take place.
In fact in one of Samsung’s ads for their Galaxy S 4 smartphone they showed this as a very neat and nifty function where pictures and video were transferred by simply touching two Galaxy S 4’s together.
