Mobile Radio Frequency Identification (RFID) is a newly emerging technology which uses the mobile phone as an RFID reader with a wireless technology and provides new valuable services to the user by integrating RFID and ubiquitous sensor network infrastructure with mobile communication and wireless internet. The mobile RFID enables business to provide new services to mobile customers by securing services and transactions from the end-user to a company's existing e-commerce and IT systems. In this paper, we will discuss mobile RFID technology. We begin with a discussion of the details of a mobile RFID system anatomy, followed by a discussion of the components that make up a typical mobile RFID system framework and the underlying sub-systems that make them work. ). Currently, RFID technologies consider the environment in which RFID tags are mobile and RFID readers are stationary. However, in the future, RFID technologies could consider an environment in which RFID tags are stationary and RFID readers are mobile. RFID based on mobile telecommunications services could be the best example of this kind of usage. RFID-based mobile telecommunications services could be defined as services which provide information access through the telecommunication network by reading RFID tags on certain objects using an RFID reader in mobile terminals such as cell phones. RFID tags play an important role as a bridge between offline objects and online information. The RFID-enabled cell phone was introduced by Nokia in 2004 (Nokia, 2004;Park and Lee, 2004;Chae and Oh, 2005;Yoo, 2005).Furthermore, the RFID tags of the future will evolve as active tags which have networking capabilities, becoming a key component of the ubiquitous network environment rather than the current passive RFID tags. In this stage, RFID tags will need network addresses for communications. For the ubiquitous network, current RFID-related technologies need to be modified to reflect the features of mobile telecommunications services; and additional technologies for RFID-based mobile telecommunications services should be established to provide harmonised operation of such services. In this paper, we will discuss the mobile RFID technology. We begin with a discussion of the details of a mobile RFID system anatomy, followed by detailed discussion of the components that make up a typical mobile RFID system framework and the underlying technologies that make them work.
BackgroundIn this section, we introduce the overview and basic service models of mobile RFID technology. And, we will discuss the mobile RFID technology's wireless specification and difference of EPC RFID network case.
UHF mobile RFID technologyThe main philosophy of the networked RFID is that it tries to remove data from the tag and manipulates the data on the network (Sarma et al., 2002). Therefore, it makes the code which tag holds as small as possible. The size of the code, which is defined by EPCglobal, is 96 bits or 128 bits. This small code size makes the cost of RFID tag cheap and resolving operation...
