IntroductionNear Field Communication (NFC), also known as short-distance wireless communication, is a type of high-frequency short-distance wireless communication technology. Provides non-contact peer-to-peer data transmission between electronic equipment within 10cm. It is widely used in our life, such as HOP card, Fly buy VISA card and mobile phone. Even for our company, which is a small company with just 10 employees, it is useful. It can be used in our login to monitor employee attendance. And we can use it in our VIP card for our members. NFC technology also has a great influence on modern marketing. Our customers can simply use the mobile phone's NFC command on NFC posters and advertisements and immediately get information about our products or services. Near Field Communication (NFC) is a technology suitable for access control, standard wireless communication equipment exchanges data several centimeters away. NFC is also fully consistent with the ISO standard management of contactless smart cards; these are the significant characteristics of the ideal platform. http://zh.wikipedia.org/wiki/%E8%BF%91%E5%A0%B4%E9%80%9A%E8%A8%8A http://android.265g.com/huati/2683. html NFC TechnologyWhat is Near Field Communication (NFC) Technology Near Field Communication (NFC) technology is a type of short-distance wireless communication technology. It was created by Philips and Sony Corp in 2003. And it is based on RFID and interconnection technology. NFC technology was initially used primarily to provide communication between phones and other portable devices. The NFC chip has functions of mutual communication, data exchange and computing ability. Therefore, NFC technology is believed to have wide applications... in the middle of paper... and services are the same way. So the company and customers can get to know each other. And this helps them to have good communication. http://rapidnfc.com/blog/74/the_benefits_of_nfc_what_can_they_offer_you Problems of Near Field Communication (NFC) Technology So far, people haven't opened the perfect thing. NFC is no exception. There are some problems in NFC technology. Initially, the short distance is a problem. NFC provides only 10cm for the longest transmission distance. It means that people would have to put together the equipment to carry out the transmission. http://electronics.howstuffworks.com/near-field-communication5.htm Because another problem involves theft. NFC equipment is easy to carry. And they are also easy to steal. Thanks to the simple way, the data in NFC equipment can be easily used by others. Once the NFC equipment is lost, the data will be easily obtained or used by others.
