CUWS provides a standard for data exchange

The purpose of Common Use Web Services (CUWS) is to standardize data exchange between Common Use self-service bag drop and Departure Control Systems using web service technology. This standardized interface between parties can be reused by both the service provider and the end user consumer (i.e. the airport/airline) and therefore makes its use cost efficient. It entails not only low initial costs but also low overall operation costs. High service availability and stability is achieved through redundant production systems and traffic is distributed using load balancing. Load balancers also allow services simply being switched off when not needed or switched on and upscaled when the demand increases.

Implementing an IPS CUWS solution allows airports and airlines to operate not only Materna IPS self bag drop but also bag drop clients of other vendors, which often require a CUWS interface for their operation. 

IPS Connect also creates a remarkable independence from Departure Control System providers because smaller changes to the service usually do not require the involvement of the DCS providers. It enables a quick service setup, since no or only a few additional hardware interfaces are required.
