The method includes: starting a business query by the client application based on geolocalization of the client user equipment; inserting a business query by a customer through the client application; sending the business query criteria to a central server to establish a query result including suppliers meeting the business query criteria; sending the query result to the client application; selecting a supplier by the customer through the client application; sending business transaction data to the central server which pushes the business transaction data to the business application; and receiving an immediate reply from the business application toward the central server which pushes the reply to the client application, to allow the business transactions to be immediately confirmed, denied or changed.

Abstract: Method for exchanging information among digital units in a distributed system, with digital units being defined by at least a master node and slave nodes, involves transferring information references from a master node to slave nodes, the information references being sampled with sampling time corresponding to a cycle time period defined by a clock value of the master node. The method also involves estimating the number of the information references sampled arrived to the slave node from the master nodes during a periodic reference time interval, and using the number to recalculate the master clock value, so that the slave nodes are able to reconstruct master node information references during a following reference time interval.
