logistics processes [12], in an adequate way and of

complete transparency [11]. At the end of each

description, solutions of treating the jeopardizing

points are emphasized. Working with RFID

protocols involves more stages: (a) stages of

installation: the system’s database and the RFID

transponders are established and initialized;

(b) stages of communication: the system’s database

and the RFID transponders communicate and

interact; (c) stages of searching: the RFID system

searches in its database the identifiers of

transponders.

Some threatening parts against the RFID

technology can be brought into mind: relay attack

and impersonation, leakage of information or

anticipation of traceability. The privacy issues

cannot be handled by using only the classical

theoretical methods, but rather by including the

privacy issues within communication methods as an

entire, starting with the physical level up to the

application level. Radiofrequency identification

brings into analysis, as any other technologies in

progress, some security issues. In many

applications, the high cost of RFID technology will

be balanced out by reaching the best solutions and

results.
