This driver may be used to create a log file of transactions as they happen. The file format is configurable with selectable separators, and delimiters. This allows various types of comma separated and tab delimited files to be created with a variety of fields present for import into another application, or simply to archive the transactions. This may be used to later process transactions manually offline, or to record the activity from another online service.
This and the other offline drivers may be used to record transactions which happen during periods when there are problems processing real time transactions with the primary gateway in use, in order not to turn away a sale.
