Near field communication system to control the electronic home appliances using RF encoder and decoder. 4-bit encoder and decoder are used for wireless 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 identifier 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.
