Abstract
A disconnected transaction system for pervasive computing devices includes a service provider server; a pervasive computing device; a communication network; and a service contract downloadable from the service provider server to the pervasive computing device over the communication network during a connected mode, the service contract specifying rules of interaction with a service application associated with the service contract and providing a service provider with a mechanism for validating, upon reconnection to the service provider server, at least one transaction of the service application performed by a user of the pervasive computing device during a disconnected mode.
