1. A contactless electronic system configured for contactless communications with a reader over an electromagnetic field and comprising a power supply, a current monitor, a processing system comprising a hardware processor configured for performing operations, a dynamic extra current loader and a clock generator, wherein:
said current monitor is configured for determining the maximal current, Imax, that can be provided by the power supply to the processing system from the electromagnetic field,
said current monitor is configured for comparing, during an execution phase of said hardware processor, said determined maximal current (Imax) and a current drawn by the processing system, Iplatform, and
said dynamic extra current loader is configured for loading an extra current, I extra, equal to Imax minus Iplatform when the current drawn by the processing system, Iplatform, is lower than the determined maximal current, Imax.
