Abstract
In an embodiment a method for dynamic power control of a power level transmitted by an antenna of a contactless reader is disclosed. The method may include supplying a power to the antenna and performing at least one power adjusting cycle for adjusting a power level during a contactless transaction with a transponder, each power adjusting cycle including modifying the power supplied to the antenna to a predetermined level of power, performing a first measuring of a loading effect on the antenna at the predetermined level of power and adjusting the power level according to the measured loading effect.
