It is the UPU's mission to help build a worldwide electronic postal payment network (WEPPN). It does this through its Postal Technology Centre's International Financial System (IFS) software suite. This suite of software tools allows postal operators to offer electronic postal payment services, providing state-of-the-art guarantees to secure payments between designated operators and protecting the interests of consumers, senders and beneficiaries alike.
The WEPPN is complemented with the UPU trademark “PostTransfer”, the automated clearing and settlement system (PPS*Clearing) and a set of additional tools for business and quality support.
