Intrinsically safe and Energy efficient

All the focus of the Active-Tag is on the energy efficiency : performing a lot with very few. The very long reading distance, typically over 100m in free space, is achieved with a very minimum output radiated power. The SAR (Specific Absorption Rate) is a measurement of how much electromagnetic radiation is absorbed by body tissue while using a mobile phone. The higher the SAR the more radiation is absorbed. In Europe, the European Union Council has adopted the recommendations made by the International Commission on Non-Ionising Radiation Protection (ICNIRP Guidelines 1998). These recommendations set a SAR limit of 2.0 W/kg in 10g of tissue. The Active-Tag limits its radiation to below 0.000009 W/kg, way below any mobile phone.
