摘要

Abstract invention patent: "communication system, method for determining the location of devices, a method to generate a list of neighboring devices, method for determining the location of a plurality of devices, method of communication via link alternative.Method to choose the form of communication between a device and one of a accrediting and a service provider and method for updating applications in POS devices. A communication system comprising at least two devices (POS 1, 10a, 10b, 11) communicating by means of at least one communication protocol.In another form, the system comprises at least two fixed bases (15) communicating by means of at least one communication protocol. It proposes methods to solve problems through communication system is proposed.Such methods are: method to generate a list of neighboring devices; the method for determining the location of a plurality of devices (1) 10a, 10b, 11, 4a, 4b, 4C, 15); the method to choose the form of communication between a device (1) 10a, 10b, 11, 4a, 4b. 4C, 15) and between a C Redenciador (12a) or a service provider (12b); a method for updating applications in devices (POS 1,10A, 10b, 11); and a communication method via alternative link.
