Import and verification of restaurant passes

To smoothly import large amounts of restaurant passes, a file-system-based processing queue is set up, which is queried at the start of the program for all existing passes and regularly queried thereafter for newly incoming passes. Each pass is subjected to tests programmed in C# .Net 2.0. The tests differ depending on a functional type standardization of the contents (pass type). If the validation is successful, the pass contents are loaded into an Access database of the customer as incoming payments and can be examined and processed in the Access front end of this database. Faulty passes are given a technical or functional error status in the database and put into an error queue. From there, they can be manually checked and transferred back into the processing queue.
