Current issues of concern, limitations

Although many RFID implementation cases have been reported, the widespread diffusion of the technology and the maximum exploitation of its potential still requires technical, process and secu-rity issues to be solved ahead of time. Today’s limitations of the technology are foreseen to be overcome and specialists are already working on several of these issues.
Standardization
Though the characteristics of the application and the environment of use determine the appropriate tag, the sparse standards still leave much freedom in the choice of communication protocols and the format and amount of information stored in the tag. Companies transcending a closed-loop so-lution and wishing to share their application with others may encounter conflicts as cooperating partners need to agree in standards concerning communication protocols, signal modulation types, data transmission rates, data encoding and frames, and collision handling algorithms. Currently, two major groups of standards are competing worldwide: one is EPC created by the Auto-ID Cen-ter and receiving the support of UCC (Uniform Code Council) and EAN (European Article Number-ing), the other is the ISO-specified (International Standards Organization) set of standards.
