NFC and RFID Radio Frequency Identification (RFID) is a wireless use of electromagnetic fields to transfer data, aiming to automatically identifying and tracking tags attached to objects. Near Field Communication (NFC) is one specific type of RFID, and shares many physical properties with it. The differences between NFC and RFID is that many extra properties were developed for NFC to enable secure mobile payments. 1.1. Radio Frequency Identification (RFID) RFID was first patented in 1983 and is the precursor to NFC. The physical theoretical fundamental for RFID is the inductive coupling principle between transmitting and receiving devices. It enables a one way wireless communication between two objects, one is a RFID tag and the other is a RFID reader. RFID tags are attached to the objects to be identified and store information for them. They can work actively by transmitting signals frequently, or passively by waiting for the RFID reader to illuminate them. Tags can either be read-only, with a factory-assigned serial number which is used as a key into a database, or may be read/write, where object-specific data can be written into the tag by users. Field programmable tags may be written once while read multiple times. “Blank” tags can be written with an electronic product code multiple times by the user and be read as much times as people like after written successful. RFID Tags is made up with at least two parts: an integrated circuit for storing information…

INTRODUCTORY SUMMARY The internet of things is a global infrastructure for technology, enabling services by connecting things based on existing and evolving information and communication (Brown, 2015). After checking useful websites and reviewing books and articles, I recommend M-Global should include a new department for internet of things. The department will conveniently manage our technological connections as well as improve communication with other companies and government agency’s…
