NEAR FIELD COMMUNICATION       Near-Field communication(NFC) is sending data over radio waves. a communication between two electronic devices over a distance of 10 cm or less.                                                                                                                                                                                 NFC technology was initially inspired by  Radio frequency identification( RFID). NFC is implemented to make the connection faster nowadays NFC is used in many smartphones and credit cards to make faster payments.         In NFC we can send and receive communication  messages but in RFID we can send but we cannot receive any message.            Nowadays   mostly we are using share it, google files,xender, etc.these apps are based on wifi direct. with this NFC we can make the data transfer as much faster.                                                  NFC Tags:         NFC tags are passive devices, which means that they operate without a
