Registration Processor (Regproc) is a backend processing engine to enable the ID Lifecycle management. The diagram below shows the Registration Processor along with the other modules that contribute in issuing a Unique Identification Number(UIN) for an individual. Internally, Regproc follows the SEDA architecture where data flows via multiple stages till the UIN is issued.
