NFC mifare ultralight chip is installed on a mobile phone, mobile phone can realize small electronic payment and read other NFC devices or label information. NFC short interaction greatly simplify the whole certification identification process, make to visit each other between the electronic equipment is more direct, more safety and more clearly. Through the NFC, computers, digital cameras, mobile phones, pdas, and other equipment can be very convenient for the wireless connection between achieving data exchange and service.
