RFID technology is a non-contact radio frequency identification technology that uses a reader to read the code on the tag attached to the object. The code on each tag is unique, so it can effectively identify the object in the environment. RFID Gradually replacing the barcode (barcode) technology must be moved and read, and has become the mainstream in the field of identification technology. Today, it has been widely used in many different fields such as supply chain management, healthcare, access control and monitoring. Near Field Communication (NFC) is a new mobile computing technology that integrates RFID and wireless network interconnection technology. Through the non-contact reading of NFC, users can easily read the tag data that needs to be recognized, which is more convenient than traditional barcodes. The forum is an industry group composed of leading smartphone manufacturers Nokia, Sony, Philips and other companies, aiming to popularize NFC applications. M.urden proposed the following five NFC applications: Touchand Go: commonly used in logistics management, access control management, ticket inspection, etc. When the NFC device passes through the boarding gate equipped with a reader, it will be read. Touch and payment: Electronic money packaging is an application transaction task that brings the NFC device close to the reader to complete the transaction. Touch and connect: Two NFC communication devices can transmit and exchange data with each other. Touch and explore: Users can get relevant information by bringing the NFC device close to the marked file or billboard. Load and touch: Users can download the digital authentication wireless network as a check in the following ways and apply it to access control management and identity verification.
