Government service improvement?

When we are looking for a place to live we need to get this debt register. And the government offices or neighborhood offices provide this service for 18chf in person or 21chf by post, but they can't send the document digitally.
The post office doe provide a service of checking you identity and providing the document by email I less than 2h and even in times while the government offices are closed, which means they have an automation and access to do so and charge 10chf for this automation.
Why doesn't the government offer the same service? Wouldn't it even ease the workload in the offices? And clearly it already exists and they know which data they are sharing.
