A method of obtaining payer authorization for a purchase instrument transaction with a customer includes using a wireless device of a merchant to contact a virtual terminal service to process the transaction, entering transaction information into the wireless device, which transaction information includes an account identifier relating to the purchase instrument of the customer, forwarding the transaction information from the wireless device to the virtual terminal service, receiving at the wireless device a request from the virtual terminal service to receive payer authorization information from the customer, receiving the payer authorization directly from the customer into the wireless device of the merchant, forwarding the payer authorization from the wireless device to the virtual terminal service, and receiving an approval message from the virtual terminal service at the wireless device of the merchant.

A storage object such as a virtual disk drive or a raw logical volume is contained in a UNIX compatible file so that the file containing the storage object can be exported using the NFS or CIFS protocol and shared among UNIX and MS Windows clients or servers. The storage object can be replicated and backed up using conventional file replication and backup facilities without disruption of client access to the storage object. For client access to data of the storage object, a software driver accesses the file containing the storage object. For example, a software driver called a virtual SCSI termination is used to access a file containing a virtual SCSI disk drive. Standard storage services use the SCSI over IP protocol to access the virtual SCSI termination. An IP replication or snapshot copy facility may access the file containing the virtual SCSI disk drive using a higher-level protocol.

The invention discloses an intelligent substation simulation system based on a panoramic replace mode and an integration testing method for the intelligent substation simulation system. The intelligent substation simulation system is characterized in that the panoramic data simulation system comprising special third-party devices or PCs (personal computers) replaces actual secondary equipment of a substation, all interactive data of information of the total substation are simulated by SCD (substation configuration description) files imported into the total substation, information interaction between the intelligent substation simulation system and tested equipment is carried out, and the correctness of configuration of the tested equipment and even the integral system, the correctness of virtual terminals and the correctness of special properties are verified. The intelligent substation simulation system and the integration testing method have the advantages that the fixed simulation devices replace large quantities of actual engineering equipment in the integration testing method in the intelligent substation panoramic replace mode, troublesome operation for panel transportation, system construction, network connection and the like in an integration testing procedure is omitted, adverse effects due to errors when large quantities of engineering devices are manually configured can be avoided, an integration testing process is simplified, a large quantity of testing time is saved, the integration testing efficiency is improved, integration tests can be carried out in a large scale advantageously, and requirements of large-scale construction for intelligent substations are met.
