Finding the right card is time-consuming and inefficient. Cards get lost or expire. Validity is not monitored in an analogue system. GMS offers a quick and adequate solution for this. Cards are accessible and easy to find thanks to digitization.
However, digitization will not achieve efficiency benefits without good indexing. Indexing on registration characteristics such as name, date, place of residence etc. ensures fast searchability. This makes it easy to find the cards you are looking for.
