RFID Gradually replace Bar Code Technology

RFID technology is a non-contact radio frequency identification technology, which USES a reader to read codes on tags attached to objects.The code on each tag is unique, so it can effectively identify objects in the environment.RFID has gradually replaced barcode (barcode) technology which needs to be touched and read, and become the mainstream of identification technology field. Now it has been widely used in many different fields, such as supply chain management, medical care, access control monitoring and so on.Near Field Communication (NFC) is a new mobile computing technology integrated by RFID and wireless network interconnection technology.Embed NFC function in small mobile devices, such as mobile phone, PDA, digital camera, etc.Through the non-contact reading of RFID, users can easily read the tag data needed to be identified, which is more convenient than the traditional barcode.The NFC forum, an industry group of leading smartphone makers Nokia, Sony, Philips and others, aims to popularize NFC applications.M.urden proposed the following five types of NFC application: Touchand Go: it is often used in logistics management, access control management, ticket inspection, etc., when NFC equipment passes through the gate equipped with reader, it is read.Touchand Pay: the electronic currency package is an application that puts NFC devices close to readers with transaction tasks to complete transactions.Touchand Connect: two NFC communication devices can transmit and exchange data with each other.Touchand Explore: users can get relevant information by approaching NFC devices to tagged files or billboards.Loadand Touch: users can download digital authentication through wireless network as a check and apply it to access control management and authentication.
