Abstract: Use of wireless technology to enable Point of Sale (POS) vending for Multi-Function Devices (MFDs) is disclosed. A user can enable the MFD through the Internet by calling or accessing a centralized server,. The user can access a previously existing account or establish a new account. Also, one time use of the MFD can be enabled by entering credit or debit card information. Previously existing accounts can be recognized by the caller's phone number or other mechanism. Individual MFDs can be recognized by Global Positioning System (GPS), an access number, or by entering the MFD identification number. The server can transfer billing information, MFD or account restrictions, and available balance to the user. The MFD prevents users from overdrawing their account or from running prohibited jobs. Charges incurred are transmitted back to the server for account maintenance.

Abstract: An extended Foreign Device Interface (FDI) to external devices provides point of sale accounting for use of a Multi-Function Device (MFD). Simple Network Management Protocol (SNMP) can be used, in addition to the very limited page oriented interface used on copiers, to access much more detailed information about a job, permitting accurate billing by feature use, including for scan only jobs that are not currently supported. The interface also permits the external device to control job status, allowing approval of a job only after a complete cost has been computed.
