The brand new mobile devices are capable to access data networks and they are also able to execute complex applications. Furthermore, these devices implement location systems like GPS. The combination of both capabilities can be useful to build new ubiquitous applications based on user location. These applications provide to service customers valuable information related to their location. We present a new scheme to access Location-Based Services (LBS) which joins both the anonymity of its users and the privacy of their data with the capacity of providers to charge them. The protocol we describe here is based on micropayment schemes and it also adds for the first time a fair exchange between the service provider and the user, which is a micropayment for a location-based service.
