sending, to the user device, a confirmation message indicating that the single session is established;

receiving, by the one or more processors, digital data from the user device via the wireless communications;

receiving, by the one or more processors via the wireless communications, at least one action to be performed during the single session;

determining that the at least one action is permitted based on a set of approved actions associated with the account;

performing the at least one action, by the one or more processors, using the digital data;

sending, by the one or more processors and to the user device, a status associated with performing the at least one action; and

modifying, by the one or more processors and based at least in part on the at least one action and the digital data, the amount of credit in the account to create an updated credit amount.

9. The method of claim 8 , wherein:

the service device comprises a printer; and

performing the at least one action based at least in part on the digital data comprises:

determining that the digital data comprises a document and printing parameters;

determining that the at least one action comprises printing the document;
