    Abstract: This post-paid process and system for disconnected terminals solves the problem of a disconnected terminal being able to perform post-paid operations securely, using an electronic device of the user to communicate with a central server which creates a token with a temporal validity that serves to activate a compound of the disconnected terminal and, optionally, additional hardware. All operations performed in the terminal are locked to make it impossible to alter the data and signed with a cryptographic key before using the client device as transportation for the operations block to be processed in the central server and charged.
