Near field communication (NFC) is a short-range wireless protocol that allows users to connect devices and access content and services by simply holding enabled devices near each other. Many of the existing applications (ticketing, purchasing, device configuration, etc.) use NFC as a method to transfer unique identifiers which then inform a larger system. An innovative method of designing a multipurpose near field communication system using RF encoder and decoder. 4-bit encoder and decoder are used for wireless communication so that we are going to use 434 mhz rf receiver and transmitter chip .It will control multiple devices at a time. By using RF encoder we can store data without encoder we can’t send data
