The systems of low frequency correspond to equipments acting between 100 KHz and 140KHz. Generally the most used frequencies are 125KHz and 134KHz.
The choice of Texas Instrument is of 134KHz, Impro of 125 KHz.
Advantage: the low frequencies undergo less the effects of materials in base of metal or liquids. Reason for which some peach departments or automobile’s opted for this type of materials.
Inconvenience: : one single tag in reading at the same time. Tags generally are more expensive and stronger than HF tags but has lower capacity in memory.
