Abstract	In this article, Very Crucial subject discussed in RFID TAG's stability. RFID Equivalent circuits of a Label can be represent as Parallel circuit of Capacitance (Cpl), Resistance (Rpl), and Inductance (Lpc). We define V(t) as the voltage which developed on the RFID Label and dV(t)/dt is the voltage time derivative. Due to electromagnetic interferences there are different time delays respect to RFID Label voltage and voltage time derivative. We define V1(t) as V(t) and V2(t) as dV(t)/dt. The delayed voltage and voltage derivative are V1(t-τ1) and V2(t-τ2) respectively (τ1≠τ2). The RFID equivalent circuit can be represent as a delayed differential equation which depending on variable parameters and delays. The investigation of RFID's differential equation based on bifurcation theory [1], the study of possible changes in the structure of the orbits of a delayed differential equation depending on variable parameters. The article first illustrate certain observations and analyze local bifurcations of an appropriate arbitrary scalar delayed differential equation [2]. RFID Label stability analysis is done under different time delays respect to Label voltage and voltage derivative. Additional analyze the bifurcations of a RFID's delayed differential equation on the circle. Bifurcation behavior of specific delayed differential equations can be encapsulated in certain pictures called bifurcation diagrams. All of that for optimization of RFID TAG's dimensional parameters analysis under electromagnetic interferences to get the best performance.
