The Swiss post/telegraph/telephone company includes a department that runs a financial payments system. Customers hold interest-bearing accounts, and transactions on these accounts are made in a similar fashion to 'normal' banks. In practice, these accounts form the major means of non-cash payments (also to and from banking accounts) in Switzerland.

This system has been realized and Version 2 is now in operation. As this article is being written, approximately 1/2 of the data records have been brought on-line and more are coming every weekend. Work is proceeding on Versions 3 and 4 (added functionality).
Ada has been in use in Paranor since 1985 and there has never been a suggestion that we use anything else. All active programmers are agreed that a switch to another language would mean a marked reduction in programming comfort and ultimately an inferior product.
