Abstract
A method and a system for updating a counter of an electronic component in which are stored recordings, each containing at least one individual value and at least one sorting value, including: transferring into a memory of a reader an initial count of the counter and said recordings; calculating on the reader side an intermediary count equal to the minimum of the initial count and of the sum of the individual values of the recordings, the sorting value of which is within a range known by the reader; and transferring into the counter of the electronic component a number which is a function of the intermediary count.
