IntroductionNear field communication (NFC), also known as short-range wireless communication, is a kind of high-frequency short-distance wireless communication technology. It enables contactless peer-to-peer data transmission between electronic equipment within a 10 cm radius. It is widely used in our life, such as HOP card, Fly buy VISA card and mobile phone. For our company, as a small company with around ten employees, it is also useful. It can be used during our login to track 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 customer can simply use the NFC mobile phone film on NFC posters and advertisements and can immediately get information about our products or services. Near field communication (NFC) is an appropriate access control system technology, standard wireless communication equipment data exchange between several centimeters of distance. NFC is also fully compatible with the management of the ISO standard for contactless smart cards; these are the important 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 kind 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. In the beginning, NFC technology was primarily used to enable communication between phones and other portable devices. The NFC chip has the function of mutual communication, data exchange and computing capability. Therefore, NFC technology is considered to have many applications...... middle of paper ... and services are the same. This way, 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 with Near Field Communication (NFC) TechnologySo far, people have not discovered the perfect thing. NFC is no exception. There are some problems in the NFC tchonoloy. At first, the short distance is a problem. NFC only provides 10cm for the longest transmission distance. This means that people must gather equipment to make the transmission. http://electronics.howstuffworks.com/near-field-communication5.htm Another problem is theft. NFC equipment is easy to carry. And they are also easy to steal. Thanks to their simplicity, the data contained in NFC equipment is easily used by others. NFC equipment once lost whose data will be easily obtained or used by others.
