The fiskaltrust.Middleware is an integrated set of highly configurable software components for POS systems to abstract the complexity of national fiscalization laws.
National fiscalization laws highly differ between most countries, and are often very complex to understand and implement. The fiskaltrust.Middleware abstracts this complexity behind a common international interface, so that creators of POS software can focus on their core business and features.
The Middleware itself is free, and part of a bigger ecosystem and platform that includes features for automated rollouts and maintenance, user onboarding, and much more. On top of this, the Middleware can be used with fiskaltrust's optional add-on products for revision-safe storage and 3rd party integrations.
If you're a PosCreator (i.e. a software developer who's creating POS software and wants to implement the Middleware), please have a look into our getting started guide for PosCreators first.
If you're a PosDealer - and thus interested in rolling out the Middleware to your end customers -, please check our getting started guide for PosDealers.
The Middleware is highly configurable by combining different packages into a CashBox configuration container. These packages are then either hosted on-prem by the platform-independent fiskaltrust.Launcher application, or in the cloud (either by yourself or by fiskaltrust).
There are three categories of packages:
Documentation and release notes are maintained on GitHub (look for the -doc
postfix in our repositories), and available on docs.fiskaltrust.cloud.
In general, we welcome all kinds of contributions and feedback, e.g. via issues or pull requests, and want to thank every future contributors in advance!
Please check out the contribution guidelines for more detailed information about how to proceed.
For development purposes the queue/fiskaltrust.Middleware.sln
solution and SCU market solutions (e.g. scu-it/fiskaltrust.Middleware.SCU.IT.sln
) contain TestLauncher projects (queue/test/Manual/fiskaltrust.Middleware.Queue.Test.Launcher/Program.cs
, scu-it/test/TestLauncher/Program.cs
).
To run a queue or scu using the test launcher you need to configure a sandbox cashbox and set the cashboxId and accessToken (and localization for a queue) in the Program.cs
file of the TestLauncher.
You can start a debugging session from VisualStudio or VisualStudio Code and debug the launcher there.
Or you can then start the TestLauncher on the commandline like so: dotnet run --project queue\test\Manual\fiskaltrust.Middleware.Queue.Test.Launcher\fiskaltrust.Middleware.Queue.Test.Launcher.csproj
.
Note: You may need to start the TestLauncher as an administrator or windows does not allow the ports to be bound. For that you need to start VisualStudio as an administrator.
The fiskaltrust Middleware is released under the EUPL 1.2.
As a Compliance-as-a-Service provider, the security and authenticity of the products installed on our users' endpoints is essential to us. To ensure that only peer-reviewed binaries are distributed by maintainers, fiskaltrust explicitly reserves the sole right to use the brand name "fiskaltrust Middleware" (and the brand names of related products and services) for the software provided here as open source - regardless of the spelling or abbreviation, as long as conclusions can be drawn about the original product name.
The fiskaltrust Middleware (and related products and services) as contained in these repositories may therefore only be used in the form of binaries signed by fiskaltrust.
