Abstract: The invention relates to a method for monitoring the wear of a pair of hand pliers with which crimping elements can be pressed onto a workpiece and a particular degree of crimping mp, to be obtained by actuating the pliers, set using a presetting device. An arrangement is described for carrying out this method, as is a pair of hand pliers implementing the method. The method includes: counting each actuation of the hand pliers and linking to the degree of crimping mp that has been set; reading out a wear prognosis value Vt, from a memory, for the degree of crimping that has been set; determining a total wear value V by adding up the wear prognosis value Vt for each actuation; verifying whether the total wear value reaches or exceeds a defined threshold value VG, and issuing a calibration request if necessary.

Abstract: Method for carrying out a transaction on a system that includes at least one central processing platform, at least issuer server and at least one acquirer server, wherein the central processing platform includes a routing engine coupled by a communication connection to the issuer server and the acquirer server, and the method includes the steps of receiving a transaction inquiry at the acquirer server or the issuer server, routing of the inquiry from the acquirer server or from the issuer server to the central processor platform, and operating the central processor platform, in order to implement the transaction.
